Tue Jul 1 11:53:27 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.5.6
* enhancement: the compiler now recognizes when local functions (both named
and anonymous) are used only as downward funargs in many situations and
can stack allocate such closures even without explicit dynamic extent
declarations. See the updated manual entry on stack allocation for more
information and how user-code can declare funargs as downward.
* minor incompatible change: optimization notes for a variable declared to
be of type LIST will not be emitted for various transforms which are
defined to operate on (OR NULL VECTOR).
* minor incompatible change: some forms, including a THE form with an
invalid type specifier, or a CASE form with bad entries, no longer produce
a runtime error. (They continue to provide a full warning at
compile-time).
* platform support
** on arm64, breakpoint-based stepping is now thread-safe.
** on arm64, backtraces after interrupts should be more correct.
** on x86-64 with the immobile-space feature, calling from assembly
routines to lisp routines is more efficient.
** if arenas are enabled, users can define a lisp function to act as a
handler to customize behaviour on arena exhaustion.
* bug fix: address several bugs related to dynamic-extent declarations,
inference, and stack allocation.
* bug fix: the stack return page protection is temporarily disabled during
GC, so that GC can complete even if it needs to write in the return page.
* bug fix: the compiler generates code to the right entry point for specialized
functions. (lp#2111876, reported by Matt Kaufmann)
* bug fix: the compiler's constraint derivation would sometimes not terminate.
(lp#2113747)
* bug fix: when the runtime structure representing a thread is re-used, the
stack guard pages are restored.
* bug fix: type checks for &OPTIONAL arguments are done only once.
* bug fix: CEILING's docstring was wrong. (reported by Dave Tenny)
* bug fix: APPLY could be called with too many arguments when parsing MEMBER
type specifications. (reported by Zach Beane)
* bug fix: the compiler could allow constant values of bad types to trigger
optimizations. (lp#2113977)
* bug fix: internal compiler error when attempting to write out a type check
for a value already proved to never exist (i.e. be of type NIL).
(lp#2112475)
* optimization: better division for signed-word dividends and unsigned-word
divisors on arm64 and x86-64.
* optimization: improvements to subtraction involving bignums and words on
x86-64.
* optimization: perfect-hash-based transformations are applied to sequence
functions with keys including fixnums and characters as well as symbols.
-------------------------------------------------------------------
Tue Jun 3 08:49:52 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.5.5
* minor incompatible change: the output from TRACE is now prefixed by a
FRESH-LINE on *TRACE-OUTPUT*.
* platform support:
** On Linux, the system is better at negotiating with the kernel to find
locations for Lisp memory spaces, succeeding more often than
previously.
* bug fix: resolve signed/unsigned char mismatch in RUN-PROGRAM on Windows.
(lp#2110525, reported by awlygj)
* bug fix: compiler confusion given sufficiently complex derived type
constraints. (lp#2109902)
* bug fix: compiler inconsistency in low-level representation leading to
inconsistent transformations. (lp#2109837)
* bug fix: return NIL from calls to DOCUMENTATION on illegal function names.
* bug fix: calls to APPLY or VALUES-LIST on some combinations of constant
arguments could lose the constant nature after transformation. (thanks to
Hayley Patton)
* optimization: some micro-improvements to bignum operations, particularly
on x86-64 and arm64
* optimization: allow the result of MAKE-STRING to be allocated on the stack
when :element-type is unknown.
* optimization: the compiler will recognize the use of ZEROP on the results
of LENGTH and REM (on suitable operands) to avoid full computation of the
intermediate result.

-------------------------------------------------------------------
Tue Apr 29 07:56:09 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.5.4
* enhancement: :FUN-END breakpoints now support the known values return
convention when DEBUG > 0. This means that tracing local functions works
in more situations.
* platform support:
** on x86-64, relocation of static space is always enabled.
** save-lisp-and-die with :callable-exports can be used for sbcl.dll on
Windows.
** Building with UCRT64 on Windows is now fully supported.

processor to their uses. (lp#2106358, reported by Vasily Postnicov)
* bug fix: fix compilation error from CHECK-TYPE when the value checked is a
keyword argument and the type specifier argument is not a valid type
specifier. (lp#2104089)
* bug fix: generate stack-manipulation code in the presence of non-local
exits and dynamic-extent declarations even more carefully. (lp#2043242)
* optimization: (LOGIOR A (- (MASK-FIELD (BYTE 1 constantN) A))), or its
equivalent (LOGIOR A (- (LOGAND (ASH 1 constantN) A))), is recognized as
an idiom for sign-extending the N+1-bit field in A, and can be used for
signed modular arithmetic.
* optimization: ROUND is faster for floats.
* optimization: TRUNCATE/FLOOR/etc. are faster on ratios.
* optimization: MAKE-SEQUENCE does not invoke the full type algebra when the
provided type specifier is simple.
* optimization: don't attempt to align branch targets if the SPACE
optimization quality is greater than 1.
* optimization: circularity detection for printing now places its temporary
data structures on the stack.
* optimization: faster GCD on fixnums, especially when the difference in
magnitude is large.
* optimization: the implementation of ISQRT has been replaced with the
(faster) algorithm currently implemented in CPython.
-------------------------------------------------------------------
Sun Mar 30 21:28:01 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.5.3
* enhancement: breakpoint debugger commands have been added. Included is a
stepper based on breakpoints requiring no extra instrumentation. However,
it still has less functionality than the existing single stepper. See the
new debugger manual section titled "Breakpoint Commands" for more
information on the new commands.
* minor incompatible change: the behaviour of :save-runtime-options has been
restored to match the documentation. (lp#2096995, reported by Zach Beane)
* minor incompatible change: invoking CHANGE-CLASS from user code no longer
grabs the CLOS world lock. Callers must take responsibility for ordering
execution of CHANGE-CLASS and any changes to the class hierarchy.
* platform support:
** (CAS SAP) is implemented on ARM v8.1 directly with CAS instructions.
** on x86-64, list constructors emit more compact code sequences,
particularly in the presence of multiple references to the same object.
** on x86 and x86-64, fix the stack overflow check to use signed
comparisons.
** on Darwin/arm64 and Linux/x86-64, provide a restart to disable
floating-point exceptions of the type signalled, and another to disable
all floating-point exceptions.
* bug fix: cycle detection in class precedence lists happens before adding
classes to the direct subclasses of the parent.
* bug fix: stack-allocated unaligned cons cells no longer cause errors in
the debugger.
* bug fix: local function type declarations no longer inhibit tail calls in
(SAFETY 0) code. (lp#2039301)
* bug fix: bad or unknown type specifiers in CHECK-TYPE do not crash or slow
down the compiler. (lp#2102644, lp#2102653, lp#2102714, lp#2104048)
* bug fix: numerous bug fixes relating to the type system's handling of
arrays make SUBTYPEP more reliable and less likely to express a
contradiction. (lp#1996980, lp#2100563, lp#2100728, lp#2100779,
lp#2100784, lp#2100812, lp#2100825, lp#2101192, lp#2101215, lp#2101803,
lp#2102684)

(lp#2102759)
* bug fix: startup tuning for particular microarchitectures no longer
accidentally disables one of the optimizations.
* optimization: ROW-MAJOR-AREF is transformed to use the same array
machinery as one-dimensional array references. (Thanks to Scott Burson
for the suggestion)
* optimization: list constructors emit shorter code sequences on x86-64,
particularly in the presence of multiple references to the same object.
* optimization: FLOOR and CEILING on ratios do not unnecessarily cons.
* optimization: provide specialized CALL-NEXT-METHOD functions for the
no-argument and full-argument cases.
-------------------------------------------------------------------
Sat Mar 1 21:47:13 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.5.2
* minor incompatible change: in some instances when the compiler cannot
prove that a NIL-valued branch is unreachable, where NIL is not compatible
with the expected type, a type warning will no longer be issued.
* minor incompatible change: the compiler will more strictly treat type
declarations for &OPTIONAL and &KEY arguments in FTYPE declarations, no
longer effectively adding an implicit (OR ... <default>) type when the
function itself has a default value not matching the declared type for
that argument.
* enhancement: type errors in structure constructors are now restartable,
with a USE-VALUE restart provided.
* enhancement: CHECK-TYPE warns about type conflicts at compile-time.
* enhancement: FTYPE declarations for functions which set their parameters
are checked.
* enhancement: new print control variable SB-EXT:*PRINT-CIRCLE-NOT-SHARED*,
when used in conjunction with *PRINT-CIRCLE*, prints #1# only for
circularities and not simple sharing.
* platform support
** on Windows, make sure to commit memory after zeroing during
save-lisp-and-die. (lp#2097197, reported by _3b)

single-float registers.
** on arm64, improve type checking for (AND SYMBOL (NOT NULL)).
* bug fix: using structure read macros with shared structure markers no
longer signals type errors when the shared structure is in a slot with a
type. (lp#308936)
* bug fix: non-conforming user macros which modify their source no longer
trigger internal errors. (lp#1371719, reported by _3b)

- Drop strip-arm-CFLAGS.patch, fixed upstream
-------------------------------------------------------------------
Wed Jan 8 15:39:17 UTC 2025 - Jan Engelhardt <jengelh@inai.de>
- Remove old specfile constructs
- Replace xargs by more direct find -exec.
- Trim redundancies from description (already present
in License: field)
- Split /usr/bin/sbcl to a separate package (sbcl-bin.rpm).
Because SBCL-using programs ship a static copy of the standard
library anyway, they need not pull in the standard library
(sbcl.rpm:/usr/lib/sbcl/sbcl.core) itself any longer.

expanded from macros that copy their input forms.
* bug fix: the method-combination generic function caches were missing some
of the generic functions constructed during the PCL build itself.
(reported by Didier Verna)
* bug fix: SXHASH on equal PATHNAME objects could return different values in
different cores. (reported by Luís Borges de Oliveira)
* bug fix: spurious compiler warnings on SORT in some circumstances.
(lp#2065609, reported by William G Lederer)

SB-THREAD package. (lp#2063385, thanks to Benjamin Lee)
* bug fix: compare-and-swap works as expected on SLOT-VALUE of
FUNCALLABLE-STANDARD-OBJECT instances. (reported by qhong)
* bug fix: on arm64, and x86-64 with some non-default build options, integer
rounding functions treat minus zero more consistently.

(reported by bohonghuang)
* bug fix: don't leak memory when decompressing a compressed core.

sometimes smaller.
* optimization: on arm64 and x86-64, list accumulation is done with less

- Update to version 2.4.3
* enhancement: when dumping debug information to fasl files, the system
respects the SOURCE_DATE_EPOCH environment variable (if set) as the latest
timestamp to be used.

* bug fix: erroneous transform of EQUALP on characters (lp#2055425)
* bug fix: float rounders (FTRUNCATE and related functions) handle minus
zero more consistently, returning minus zero as the primary value when
rounding to zero from a negative value.
* bug fix: type checks for (VECTOR T) were giving the wrong answer for
vectors displayed to simple multi-dimensional arrays. (reported by
_death)
* bug fix: do not transform away division by BIT when the BIT might still
include 0. (lp#2056184, reported by xizang)

not lose precision through a single-float intermediate argument.
* bug fix: LOG to the base 2 of integer powers of 2 are more likely to get
the mathematically precise answer.
* bug fix: LOG on ratios very near 1 with numerator or denominator being
near a power of 2 will use log1p and so will lose less precision.
* bug fix: the utf-8 external format with Unix line-endings updates its
character size information when taking the fast path for a buffer of ascii
characters. (lp#2054169, reported by John Carroll)

* optimization: the compiler runs a jump-to-jump elimination pass on x86-64.
* system integrity: compiling the system itself on x86-64/linux now produces
bitwise-identical cross-compiled fasls whether the build host is cmucl,
ccl, clisp or sbcl itself.
- Replace deprecated %patchN with %patch -PN for compatibility with RPM 4.20
-------------------------------------------------------------------
Thu Feb 1 09:26:07 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>

- Use existing sbcl package by default to build sbcl
-------------------------------------------------------------------
Mon Jan 1 18:15:01 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.4.0
* minor incompatible change: *COMPILE-VERBOSE* and *LOAD-VERBOSE* are bound
to NIL when the system is started with the --script command-line argument.
(reported by Hraban Luyat, thanks to Nicolas Martyanoff)
* minor incompatible change: when looking for its core file, the system
checks the validity of whatever is pointed to by /proc/self/exe, and
assesses argv[0] if /proc/self/exe is invalid. (thanks to Philipp Marek)
* minor incompatible change: the system no longer provides type names on the

-------------------------------------------------------------------
Wed Dec 6 12:10:25 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.11
* minor incompatible change: streams with an external-format specified with
:REPLACEMENT will use their replacement data once per stream unit that
causes a decoding error (rather than, in some cases, once for a sequence
of bytes none of which is a valid character start position for that
external-format).
* minor incompatible change: external-format designators with unsupported or
unrecognized options now signal an error when used.
* enhancement: During generic function dispatch, for a generic function
using standard- or short-method-combination, if there are no applicable
primary methods the system will call the generic function
SB-PCL:NO-PRIMARY-METHOD, whose default behaviour is to signal an error.
Users may define methods on this generic function.
* enhancement: external formats for unibyte encodings and utf-8 now support
newline variants.
* enhancement: character decoding and encoding errors signalled by stream or
octet functions now provide a USE-VALUE restart for handlers to provide
replacement input or output.
* enhancement: READ-SEQUENCE and WRITE-SEQUENCE support user-defined
sequences; the default implementation proceeds element-by-element, reading
or writing single bytes or characters to or from the stream as
appropriate.
* bug fix: OCTETS-TO-STRING using unibyte external formats with unallocated
codepoints (e.g. iso-8859-3) correctly signal or use replacements rather
than taking bits from the address of NIL and converting those bits to
a character.
* bug fix: FILE-STRING-LENGTH now returns NIL if the input datum is not
encodable in the stream's external format.
* bug fix: table-based multibyte external formats (EUC-JP, Shift-JIS, GBK)
now honour a replacement character (in the external format or through
restarts) when encoding to octets.
* bug fix: converting from octets using the UCS-2, UCS-4 and UTF-32 external
formats no longer reads past the end of an octet array with a non-integral
number of two- or four-byte units.
* bug fix: converting from octets using the UCS-2, UCS-4, UTF-16 or UTF-32
external formats now returns a simple string, as required by the type
declaration of OCTETS-TO-STRING.
* bug fix: providing an invalid external format argument to OPEN or
WITH-OPEN-FILE (or the internal MAKE-FD-STREAM) no longer leaks a file
descriptor.
* bug fix: SB-ROTATE-BYTE recognizes out-of-relevant-range BYTE
specifications for integers before attempting to cons up enormous bignums
for masking and shifting. (lp#2042937)
* bug fix: fix type derivation on compiling SB-ROTATE-BYTE forms with
non-zero POSITION in the byte specifier. (lp#2042775)
* bug fix: fix multiple assembler errors when compiling MAKE-ARRAY,
MAKE-STRING and similar with a large constant size. (lp#2037347, lp#2038744)
* bug fix: fix internal error when compiling (SETF SBIT) with a large
constant index. (lp#2037415)
* bug fix: fix internal compiler error on invalid lambda list parameters in
LABELS. (lp#2040334)
* bug fix: fix internal compiler error when compiling some
infinitely-recursive LABELS forms. (lp#2042704)
* bug fix: fix internal compiler error when attempting to inline a jump to a
label that has been deleted. (lp#2043262)
* bug fix: FILL-POINTER should never be made to go negative. (lp#2042452)
* optimization: external formats with :REPLACEMENT no longer bind handlers
for coding errors around conversion functions, and so should cons less and
be faster.
* optimization: when the :EXTERNAL-FORMAT argument to STRING-TO-OCTETS or
OCTETS-TO-STRING is a compile-time constant, the external format is
resolved at load time rather than on each call.
* optimization: the compiler is able to constrain the types of inputs to
some functions given a derived or asserted type of the function's return
value.
* optimization: the compiler performs fewer redundant type checks in ASSOC,
GETF and similar functions.
-------------------------------------------------------------------
Thu Nov 2 10:45:12 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.10
* enhancement: The compiler now allows stack allocating vectors of any size
on all safety levels, not just those which it can prove are of sub-page
sizes. It can do this because it now inserts code to check for stack
overflow explicitly on higher safety levels.
* enhancements to the disassembler:
** on arm64, x86-64, DISASSEMBLE annotates references to static symbols.
* bug fix: calls to generic functions now detect erroneous keywords (in the
sense of CLHS 7.6.5) passed as arguments even when auxiliary methods are
applicable.
* bug fix: the standard method on SB-MOP:COMPUTE-EFFECTIVE-METHOD no longer
inserts calls to implementation-defined local macros. (reported by Daniel
Kochmański)

its displacement target. (lp#2038233, reported by James Kalenius)
* bug fix: compiler error in LOGBITP type derivation. (lp#2038241)
* bug fix: compiler error in AREF type derivation. (lp#2038659)
* bug fix: compiler internal consistency failure in overflow type checks.
(lp#2038736)
* bug fix: work around an infinite loop in type simplification by not
providing such types from the compiler. (lp#2038980, reported by Richard
Holcombe)
* bug fix: spurious run-time argument count errors from generic function
calls on arm64. (lp#2039006, reported by fiddlerwoaroof)
* bug fix: errors in SCALE-FLOAT on floating-point infinities. (lp#2039613)
* bug fix: ROOM is slightly more robust to incompletely-initialized
instances at the point of running ROOM. (Reported by Andreas Franke)
* bug fix: finalizers saved through SAVE-LISP-AND-DIE and subsequently
executed do not trigger memory faults. (Reported by Bohong Huang)
* optimization: improvements to type derivation for ISQRT, INTEGER-LENGTH,
LOGCOUNT, LOG, DENOMINATOR.
-------------------------------------------------------------------
Tue Oct 3 12:08:02 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.9
* enhancement: stack allocation via DYNAMIC-EXTENT now applies to all values
that a variable can take on (for example via SETQ), not just the initial
binding. This permits for example building complex or recursive structures
on the stack more easily via iteration. See the updated manual entry for
more details.
* minor incompatible change: some interfaces in the SB-POSIX contrib module
adhere to the spec that a NULL result from the C library is an error if
and only if errno was altered by the call. SYSCALL-ERROR will be signaled
if so.
* enhancement: the SB-POSIX contrib module provides DO-PASSWDS and DO-GROUPS
to allow users to iterate over password and group databases safely.
* platform support:
** support for Darwin on x86 and PowerPC has been restored. (lp#2033287,
thanks to Kirill A. Korinsky, Sergey Fedorov and barracuda156)
* bug fix: miscompilation due to erroneous type derivation in the presence
of multiplication of fixnums by ratios. (lp#2033695, reported by Patrick
Dussud)
* bug fix: compiler error when compiling signed- and unsigned 64-bit type
checks in some cases. (lp#2033997, reported by Eric Smith)
* bug fix: compiler error when the :INITIAL-CONTENTS argument to MAKE-ARRAY
is a constant non-sequence. (lp#2037328)
* bug fix: compiler error when constant-folding sequence functions with
:TEST or :KEY functions erroring on the given sequence. (lp#2037341)
* bug fix: compiler error when arguments to array or sequence functions
imply a very large sequence size. (lp#2037443, lp#2037348)
* bug fix: compiler error when the return value of ADJUST-ARRAY is not used.
(lp#2037450)
* optimization: function types derived by the compiler can in some cases be
propagated backwards through the intermediate representation.
* optimization: better type derivations for LDB, LOGBITP, RATIO.
* optimization: eliminate bound checks in more cases involving transitive
comparisons.
-------------------------------------------------------------------

build-time option; it can be enabled by adding
`--without-gencgc --with-mark-region-gc`
to the build command line. (Thanks to Hayley Patton)
* enhancement: Stack allocation via DYNAMIC-EXTENT is now possible for
conditionals even when not all branches are stack-allocatable. Previously
all branches needed to be stack-allocatable for the otherwise-inaccessible
subparts to get stack allocated.
* platform support:
** on Mac OS X Sonoma, loading the memory image no longer fails.
(lp#2029430, reported by cladur)
** on Darwin, we no longer reimplement nanosleep().
** on PPC64, undefined function errors now work.
** on ARM64/OpenBSD, enable the GCC TLS feature. (thanks to Sébastien
Marie)
** when building the system, only display a reasonable amount of timing
precision. (thanks to Philipp Marek)
* bug fix: handling of inlining functions compiled to return unboxed values
no longer crashes the compiler. (lp#2029020, reported by Pascal
J. Bourguignon)
* bug fix: the source location for code executed within a top-level
(EVAL-WHEN (:COMPILE-TOPLEVEL) ...) form is now more useful.
* bug fix: address a race between user threads cancelling finalizers and the
finalizer thread executing them. (lp#2029306)
* bug fix: complex division returns the same value when evaluated inline and
out-of-line. (lp#2030097)
* bug fix: the pretty-printer no longer deletes syntactically-significant
whitespace immediately preceding a newline. (lp#1985814, reported by Mark
David)
* optimization: the compiler is more aware of the result type of the
NUMERATOR function.
* optimization: EQUAL and EQUALP compile to more efficient code when the two
arguments are known to be of the same nullable type.
* optimization: converting bignums to floats uses no intermediate memory.
-------------------------------------------------------------------
Tue Aug 1 02:11:55 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.7
* minor incompatible change: MACROLET macro functions are now compiled with
(SPEED 1), leading to fewer efficiency notes being emitted when compiled
in otherwise high-SPEED environments.
* minor incompatible change: when coalescing list data, the file compiler
respects substructure equality more accurately, with the side-effect of
coalescing along CDR chains as well as CARs. (lp#2025086)
* minor incompatible change: FUNCTION type declarations for local variables
generate assertions around their use when called.
* platform support
** on OpenBSD, the regression test suite expectations have been updated.
(lp#2026809, thanks to Sebastien Marie)
** on OpenBSD, the data limit is now 1GB. (lp#2027536, thanks to
Sebastien Marie)
** on Darwin with the SB-FUTEX feature, do not use unpaired
mach_thread_self() syscalls, avoiding resource leaks when creating
threads.
** on 64-bit RISCV, add support for some REM-by-multiplication
optimizations.
** on Windows, work around a C compiler bug relating to SYSV_ABI.
* bug fix: FILE-POSITION on string output streams no longer crashes or
causes arbitrary memory overwrites. (lp#1839040)
* bug fix: the compiler no longer constant-folds POSITION to NIL if the
START or END arguments are not valid.
* optimization: the compiler derives types of &KEY arguments in local calls.
(lp#655562)
* optimization: type tests of values of known union type can be faster if
the type being tested for has a non-trivial intersection with the known
type.
* optimization: the low-level implementation of NUMBERP, REALP and RATIONALP
has been improved on x86-64 and arm64.
* optimization: the compiler removes known-NIL arguments from calls to
APPEND and NCONC, and empty sequences from calls to CONCATENATE.

- Update to version 2.3.3
* enhancement: LET-bound anonymous closures declared dynamic extent can now

event that the host emits STYLE-WARNINGs while compiling the
cross-compiler. (lp#2009493, reported by Kirill)
* bug fix: restore compilation on ARM64 with OpenBSD. (lp#2009585, reported
by okflo)

-------------------------------------------------------------------
Tue Feb 28 12:43:04 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.2
* incompatible change: the :ORDER long-form-option in
DEFINE-METHOD-COMBINATION accepts NIL as well as :MOST-SPECIFIC-FIRST and
:MOST-SPECIFIC-LAST. A value of NIL implies no particular ordering of the
methods, and so disables checks of multiple methods with the same
specializers in that group.
* bug fix: evaluate the :ORDER long-form-option in DEFINE-METHOD-COMBINATION
properly, avoiding an infinite loop in DEFINE-METHOD-COMBINATION if the
:ORDER argument leads to a cycle of compile-time constants.
* bug fix: better compile time on chains of conditionals which have gaps in
integer ranges. (lp#1992349, reported by Mykola Matvyeyev)
* bug fix: type derivation of VECTOR-LENGTH leading to wrong type handling
for MEMBER types involving vectors. (lp#2004094)
* bug fix: equality constraint propagation in the presence of constants
could cause code to be not deleted when it should have been. (lp#2006487)
* bug fix: better compile time when the compiler needs to perform checks to
see if fixnum or word computations result in overflow. (lp#2007741)
* bug fix: miscompilation on ARM64. (lp#2007758, reported by Stephen
Westfold)
* optimization: on x86-64, use SIMD instructions for UTF-8 buffer decoding;
* various type-driven optimizations:
** comparisons of rationals with constant ratios or floats;
** comparisons of unsigned-bytes with fixnums;
** comparisons of fixnums with constant powers of two;
** equality of numbers with integers too large to be exactly represented
as floats;
** arithmetic operations on a mixture of signed and unsigned word-sized
quantities;
-------------------------------------------------------------------
Mon Jan 30 09:58:31 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.1
* sb-graph has been removed. To visualize IR1 in sbcl, it is recommended to

the feature :sb-devel is enabled at build time).
* platform support:
** implement some peephole optimizations on arm64;
** support float traps on arm64;
* bug fix: package-manipulation operations within fasls work as expected in
the absence of explicit block compilation requests. (lp#2000004, reported
by Shubhamkar Ayare)
* bug fix: incorrect type simplification of certain CONS types.
(lp#1999352, reported by Paul Dietz)
* bug fix: method combination group selection interprets the symbol * as
a wildcard element within proper qualifier-pattern lists. (reported by
Maciej Katafiasz and by Daniel Kochmański)
* bug fix: &WHOLE can be used without error in define-method-combination
arguments lambda lists. (reported by Daniel Kochmański)
* bug fix: bogus debug variables generated for closure variables whose value
cell had not yet been allocated could cause segfaults and gc crashes
(reported by _death on #sbcl)
* bug fix: handling of float NaNs in two-arg numeric comparison functions is
more consistent with the required semantics in IEEE 754 when comparing
with rationals.
* bug fix: ensure that the hide-packages test passes even when the system
retains internal cross-reference metadata. (lp#2002896, reported by 3b)
* bug fix: don't trip an internal assertion in weak hash tables with
finalizers. (lp#1998064)
* optimization: load-time only code is no longer retained at runtime when
functions close over top level bindings.
* optimization: GO and RETURN-FROM now elide out-of-extent tag checks when
the compiler can prove it's safe even on high safety.
* optimization: addition of a fixnum to a bignum generates less garbage.
* optimization: in many cases, type inference and code generation is
improved for and around numerical comparison functions.
-------------------------------------------------------------------
Tue Jan 3 09:13:33 UTC 2023 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.0

reported by Andrew Patterson)
* enhancement: improvements to constraint propagation around comparison
functions.
* optimization: conditional move VOPs can work on boxed values and
produce less consing.
* optimization: NUNION and UNION are generally faster.
* bug fix: slot-makunbound-using-class can be redefined without
redefining the other slot methods. (#1956621, reported by Michał Herda)
* bug fix: GETHASH on a table created without ":synchronized t" when run
concurrently in multiple threads could have returned incorrect results.

was a string. (lp#1803727)
* bug fix: compiler consistency failure in modular arithmetic widening.
(lp#1990715)

upstream git commit [lp#1983218].
-------------------------------------------------------------------
Wed Aug 10 11:42:43 UTC 2022 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.7
* minor incompatible change: the compiler emits full WARNINGs for undefined
references to variables in TYPE and DYNAMIC-EXTENT declarations, and for
SETQ of an undefined variable. (This was the historic behaviour for
everything except the DYNAMIC-EXTENT case, which used to emit a
STYLE-WARNING, but these diagnostics got lost in a refactoring since
sbcl-2.2.2)
* minor incompatible change: literal objects (strings, in particular)
in compiled code may at the discretion of the runtime be placed in
read-only memory. Violations of CLHS 3.7.1 could produce memory faults.
If ":PURIFY NIL" is given to SAVE-LISP-AND-DIE then no read-only memory
will be used.
* enhancement: Unicode support has been updated to support version 10.0.0 of

Fri Jun 17 06:52:22 UTC 2022 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.5
* minor incompatible change: SB-EXT:*DERIVE-FUNCTION-TYPES* being NIL now
means that function calls will strictly only use type information from
proclaimed ftypes. The previous behavior (still the default) of using
derived type information from the same file is specified with :SAME-FILE.
(lp#1393302)
* minor incompatible change: RENAME-FILE now overwrites the target file on
Windows too, making its behaviour consistent with other platforms.
* minor incompatible change: inlining of local function is inhibited if
policy DEBUG = 3.
* platform support:
** single-stepping is now supported on 64-bit PowerPC platforms. (thanks
to Thomas Fitzsimmons)
** the :SB-LINKABLE-RUNTIME feature is now supported on 32-bit and 64-bit

compilation.
* bug fix: block compilation of top-level closures now work. (lp#1931730,
reported by Sean Maher)
* bug fix: streams opened from RUN-PROGRAM but left unclosed because of a
non-local exit no longer cause unrelated streams to be closed later.
-------------------------------------------------------------------
Wed May 25 09:07:09 UTC 2022 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.4
* enhancement: better constraint propagation in the compiler. Specifically,
the compiler can now derive the type of X in control flow join situations
such as
(LAMBDA (X) (ECASE (1 ...) (2 ...)) X)
or
(LAMBDA (X) (ETYPECASE (INTEGER ...) (SYMBOL ...)) X)
instead of forgetting all information about X after the E(TYPE)CASE.
* optimization: inlined functions enclosed in local macro definitions no
longer save their entire lexical environment, reducing unnecessary
memory retention.

result is not known to fit into a word (ARM64 and x86-64).
* bug fix: EQness of constants is now always preserved when block compiling.

provably-erroneous code involving sequence functions on specialized
arrays.
* platform support:
** support getting thread IDs on FreeBSD. (thanks to Felix Lange)

if more than one closure closes over the same environment. (lp#1956870,
reported by Michał phoe Herda)
* bug fix: RUN-PROGRAM with :IF-EXISTS :APPEND no longer signals an error if
the output does not exist. (lp#1958569, thanks to Ingo Krabbe)

- Update to version 2.1.11
* minor incompatible change: *COMPILE-PRINT* now defaults to NIL. T gives
the old behavior of echoing top level forms. Users who want to see a
report of the phases of compilation can use *COMPILE-PROGRESS* and the
corresponding COMPILE-FILE :PROGRESS argument.
* optimization: The compiler assignment-converts functions much more
aggressively; local or non-entry block-compiled functions
which always return to the same place are automatically converted into the
equivalent loop or goto control structures.
* enhancement: on x86-64 and ppc64 platforms, the system uses inline
instructions rather than page protection to implement a store barrier for
the garbage collector.
* enhancement: improved reporting of code deletion notes.
* platform support:
** unbound-variable restarts for amd64 are now supported.
** bug fix: single-floats to foreign functions on 32-bit ARMel.

Mon Jun 1 09:48:21 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.5
* platform support:
** experimental support for ARM32 and ARM64 on OpenBSD
** better musl libc support. (lp#1768368, thanks to Eric Timmons)
** more correct use of futexes on 64-bit Linux. (lp#1876825, reported by
Ilya Perminov)
** restore building on current Solaris. (lp#1881393, thanks to Shawn
Ellis)
* enhancement: CMUCL-style START-BLOCK and END-BLOCK declarations are now
supported for block compiling forms at a sub-file granularity.
* enhancement: IPv6 support in sb-bsd-sockets is enabled on Windows.
* minor change: *compile-print* now makes it more clear what block
compilation is actually doing. The default output is now slightly more
verbose as a result.
* bug fix: number keys in EQUALP hash tables are correctly hashed.
(lp#1878653, reported by Syll)
* bug fix: EQness is better preserved given partial sharing of list contents
in the file compiler. (lp#1583753, reported by Denis Budyak)
* bug fix: the peephole pass neglected to preserve jump table labels.
(lp#1876485)
* bug fix: fix compiler crash in block compilation merging of toplevel
lambdas. (lp#1865336, reported by il71)
* bug fix: sb-introspect's function-lambda-arglist is better at extracting
default values of nested macro arguments. (lp#1876194)
* bug fix: RESTART-BIND's body is an implicit progn, and so does not accept
declarations. (lp#1876303, reported by Michal Herda)
* optimization: EQUAL hash tables with keys involving structure-objects will
have fewer systematic collisions.
- Fix architecture mapping for riscv64 in spec file
-------------------------------------------------------------------
Tue Apr 28 07:25:18 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.4
* platform support:
** 32-bit RISC-V is now fully supported. Unlike other ports, its backend
is entirely shared with 64-bit RISC-V.
** native threads are now supported on RISC-V.
** fix and add some x86-64 vector instructions. (reported by Shubhamkar
Ayare)
** improve pointer representation on ppc64 for low-level performance
improvement.
** threads are more stable on big-endian ppc64
* enhancement: forward-referenced type tests can now be open-coded by using
block compilation. The result is that mutually referential defstructs are
now efficiently compiled in block compilation mode, superseding a lighter
mechanism that worked in fewer contexts. However, that lighter mechanism
has been removed, so for now, users who want to efficiently compile
mutually referential defstructs must explicitly opt-in using block
compilation.
* bug fix: defstructs with empty initforms in the sbcl source are now
explicitly intiialized with NIL, as that is undefined behavior under
ANSI. This helps cross compilation hosts which do not implicitly
initialize empty initform slots to NIL. (Thanks to Karsten Poeck)
* bug fix: backtracing through assembly routines now works properly on
RISC-V.
* bug fix: ASH no longer gets miscompiled in certain edge cases on RISC-V.
* bug fix: &MORE args have been slightly optimized and are more correct on
RISC-V.
* bug fix: unused local functions with &REST/&KEY/&OPTIONAL now also issue a
deletion note.
* bug fix: APPLY on a large list ("large" being in excess of 2k to 16k items
depending on the platform) can no longer crash the gencgc collector.
* bug fix: sb-concurrency FRLOCK algorithm has been corrected. (lp#1087955)
* bug fix: block compilation now respects inlining declarations better (like
CMUCL).
* optimization: hashing of structures with raw slots for EQUALP hash tables
has been improved.
-------------------------------------------------------------------
Sun Mar 29 13:19:41 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.3
* incompatible change: the external format now defaults to UTF-8 and is not
affected by LANG. sb-ext:*default-external-format* is now the only way to
change it.
* minor incompatible change: the undocumented :EPHEMERAL argument to
MAKE-THREAD has been removed.
* minor incompatible change: DECLARE type testing of structure types when
the SAFETY optimization quality is less than SPEED (but greater than 0) is
precise, rather than merely testing that an object is a (general)
STRUCTURE-OBJECT.
* platform support
** respect sunos platform assembler flag handling
** riscv architecture can be detected during the build
** enabled the sb-dynamic-core feature on riscv, sparc, and made it
unconditional everywhere
** cheneygc is an option for arm and arm64
* enhancement: the installed sbcl executable tree can be renamed or moved
without risk of incorrectly referencing a '.core' file from an obsolete
path. (lp#666086)
* optimization: transform (values-list (list one-item)) to (values one-item)
as multiple items were already recognized.
- Drop patches merged upstream
+ ppc-ppc64le-fix-LINKFLAGS.patch
- Enable bootstrapping sbcl with clisp on ppc64 and riscv64
-------------------------------------------------------------------
Fri Mar 13 21:16:28 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.2
* new feature: CMUCL-style block compilation support has been added,
allowing whole program optimization. It has been documented in a new
section of the manual entitled "Advanced Compiler Use and Efficiency
Hints". In particular, users of block compilation will find a large
speedup for numerical code, as functions which call or return floating
point values will keep everything unboxed.
* bug fix: in CHANGE-CLASS, handle non-standard slot-value-using-class for
:INSTANCE and :CLASS slots better. (reported by Shinmera on #sbcl)
* bug fix: REMHASH in an EQUAL or EQUALP hash-table works correctly on a
key for which EQUAL (respectively EQUALP) is reduced to EQ. (lp#1865094)
* bug fix: do not emit a warning for DEFCLASS slots with mismatched :TYPE
and :INITFORM when the class has a non-standard metaclass.
* bug fix: DISASSEMBLE on SPARC is less likely to spuriously annotate code
sequences as error traps.
- Add patch to add missing linker flags to LINKFLAGS on ppc and ppc64el
+ ppc-ppc64le-fix-LINKFLAGS.patch
- Refresh patches for new version
+ strip-arm-CFLAGS.patch
-------------------------------------------------------------------
Sun Feb 2 15:39:58 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.1
* minor incompatible change: some symbols have been removed from *FEATURES*
based on a determination of which should be impermissible to examine
via #+ and #- reader macros in user-written code.
* optimization: DEFSTRUCT copiers including COPY-STRUCTURE are able to
stack-allocate the result when declared dynamic-extent.
* bug fix: loop analysis code more robust. In particular, loop nesting depth
is computed more accurately, improving the register allocation around
loops.
- Refresh patches for new version
+ fix-tests.patch
-------------------------------------------------------------------
Wed Jan 1 14:45:09 UTC 2020 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.0
* minor incompatible change: heap relocation now works on Windows. Since
this feature now works on all platforms, it is enabled unconditionally and
the :RELOCATABLE-HEAP symbol no longer appears on *FEATURES* in any
builds. (Thanks to Luís Borges de Oliveira)
* enhancement: malformed type specifiers and occurrences of deprecated types
in :TYPE initargs of DEFCLASS and DEFINE-CONDITION slot specifications
are detected and result in compile-time errors and warnings respectively.
* enhancement: parallel contrib building, controlled by SBCL_MAKE_JOBS=-jX
the same as for the C runtime.
* bug fix: add a walker template for WITH-SOURCE-FORM.
* bug fix: start the summary of a compilation unit on a fresh line. (Thanks
to Zach Beane)
* bug fix: on Windows, PARSE-NATIVE-NAMESTRING produces an absolute
directory when parsing a bare drive name and :AS-DIRECTORY is specified.
(Thanks to Luís Borges de Oliveira)
* bug fix: on RISCV, the runtime is linked with libz if the core compression
feature is requested. (Thanks to Andreas Schwab)
* bug fix: ADJOIN using an EQL test and a KEY function only transforms into
an EQ test if the key function returns values for which EQ and EQL are
guaranteed to be the same.
* optimizations:
** the instruction sequence for multiple-value calls is more
efficient on x86-64.
** the direction flag is now unused on x86 and x86-64 when handling
an unknown number of return values. (Thanks to Fanael Linithien)
** the x86-64 backend is better able to use memory operands for arithmetic
operations.
** compilation of TYPECASE to a jump table is enabled when all the types
being tested are frozen.
** compilation of CASE and ECASE into a jump table has been implemented on
32- and 64-bit powerpc platforms.
** the implementation of Unicode normalization has been sped up.
** pretty-printing dispatch on conses is faster, particularly with the
standard pretty-print dispatch table. Deeply-nested forms should also
pretty-print faster.
-------------------------------------------------------------------
Sat Dec 14 22:26:24 UTC 2019 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 1.5.9
* platform support:
** a message intended to be more helpful will be displayed for an mmap
failure on OpenBSD.
** the soft-float ABI on ARM32 is better supported, in particular in
returning double floats from calls into C.
* optimizations:
** CASE and ECASE with symbols as keys may be optimized into a vector
lookup if all result forms are quoted or self-evaluating objects.
** CASE and ECASE can be optimized into a jump table on the x86[-64]
backends with arbitrary result forms provided that the clause keys
are either all fixnums, all characters, or all symbols.
** a number of forms are converted to use CASE in circumstances where that
makes sense, including calls to POSITION, MEMQ and MEMBER, and TYPECASE
where the types are MEMBER/EQL types.
** POSITION of a variable symbol in a constant sequence of symbols is
converted to CASE and thence to a jump table.
** TYPECASE of a variable where the clauses are member types is converted
to CASE and thence to a jump table.
** a number of slow instructions are no longer used on x86 and x86-64
machines. (Thanks to Fanael Linithien)
** the compiler is better at tracking the implications of branches after
EQ and EQL tests.
** parsing &KEY lists is slightly less register-intensive.
** a pattern-based peephole optimizer pass has been added, running some
simple transformations on the x86-64 backend.
* enhancements: more thorough compile-time type checking of various
initforms (defclass, &key, defstruct).
* bug fix: unions of complicated CONS types are less likely to cause an
infinite loop. (lp#1799719)
* bug fix: DESCRIBE on functions not named by extended function designators
no longer signals a type error. (lp#1850531, reported by Michal Herda)
- Changes in 1.5.8
* platform support:
** support for Mac OS X Catalina
** improvements in interoperability with C code compiled with memory
sanitization options
** libsbcl.so links to zlib when sb-core-compression is enabled.
(lp#1845763, thanks to Juan M. Bello-Rivas)
** workarounds for BSD issues around mmap() and pthread_attr_setstack().
(lp#1845936)
** support SSE for bzero if available on OpenBSD
* optimizations:
** improved type understanding and translations for division operators
(including TRUNCATE, GCD, LCM).
** sequential comparisons and branches can elide intermediate comparisons.
(lp#1847284)
** convert EQUAL and EQUALP to EQL if either of the arguments is a type
for which the structural equality predicate is identical to the simpler
equality check. (lp#1848583)
** internal operators implementing string comparisons produce
simpler-to-consume values. (lp#1848776)
* bug fix: inspecting adjustable arrays and vectors with fill pointers works
better. (lp#1846191, reported by Yves Pagani)
- Changes in 1.5.7
* platform support:
** many bug fixes to the experimental 64-bit PowerPC/Linux port, to the
extent that the little-endian variant passes all applicable tests in
the regression test suite; the big-endian variant currently has some
failures
** experimental support for sb-threads on 64-bit PowerPC/Linux
** support threads on x86-64 Sun OS (lp#1841280)
** handle PAX restrictions on mprotect() on NetBSD
** experimental support for HaikuOS
** the runtime is built as a position-independent executable by default on
x86-64 Linux and x86-64 Darwin
* fixes and enhancements related to Unicode:
** update of the data files to Unicode 8.0
** fix a bug in the implementation of the Unicode line breaking algorithm
regarding hebrew letters and hyphens
* enhancement: add a restart to OPEN with :IF-EXISTS :ERROR to allow
re-opening with :APPEND. (lp#806398, reported by Tobias Rittweiler)
* bug fix: compiler optimizations on SEARCH with :FROM-END T didn't account
for the empty sequence. (lp#1844821)
* bug fix: handle SETF of nested empty VALUES correctly. (lp#1806478)
* optimization: FLOOR and CEILING on rationals are simpler, and the
compiler's understanding of them is better.
- Changes in 1.5.6
* platform support:
- experimental support for 64-bit PowerPC running Linux (extending Brian
Bokser's work from 2018), on both the v1 and v2 ABIs
* new feature: SB-EXT:SEARCH-ROOTS discovers paths from live objects to the
roots keeping them alive.
* enhancement: string output streams created with :ELEMENT-TYPE 'BASE-CHAR
use internal buffers of BASE-STRING instead of UCS-4 strings restricted
to the ASCII range, yielding a theoretical 4:1 space reduction.
* optimization: improved make-array type derivation for multi-dimensional
arrays. (lp#1838442)
* bug fix: compliant redefinition of classes whose previous definition
caused argument mismatch errors does not generate errors any more.
(lp#1840595, reported by 3b on #sbcl)
* bug fixes for issues caught by the random tester:
- never derive the type of TRUNCATE on arbitrary numbers as the empty
type. (lp#1838267)
- provide out-of-line definitions for internal machinery related to
FLOAT-SIGN. (lp#1838337)
- include COMPLEX in the derived type of SIGNUM when appropriate.
(lp#1838333)
- more correct internal type testing for function types. (lp#1838808,
lp#1838888, lp#1838986)
- don't assume that all objects of type (NOT SIMPLE-ARRAY) have an array
header. (lp#1838827)
- recognize that PHASE on non-positive numbers can return 0 as well as PI.
(lp#1838892)
- Changes in version 1.5.5
* platform support:
- SunOS: bug reports and patches from Richard Lowe in sb-posix tests
(lp#1837495), sb-concurrency tests (lp#1837817), unencapsulated tracing
(lp#1837307), float registers in interrupt contexts (lp#1837168)
* bug fix: do not generate version.lisp-expr from git describe if the git
repository is not sbcl's own. (lp#1836663, thanks to Richard Lowe)
* bug fix: compiler crash related to VALUES-LIST on a &REST argument in some
contexts. (lp#1836096, reported by Samuel Jimenez)
* bug fix: compiler hang related to constraint propagation. (lp#1835599,
reported by Mark Cox)
* bug fix: the inspector showed the wrong array element type. (lp#1835934,
reported by Richard M Kreuter)
* optimization: numerous improvements to hash table access and rehashing

Tue Jul 16 12:25:02 UTC 2019 - Jonathan Brielmaier <jbrielmaier@suse.de>
- Update to version 1.5.4
for changes since version 1.4.7 have a look at the NEWS file
- refresh patches:
* fix-tests.patch: remove second part of patch as the grent.2 test
in contrib/sb-posix/posix-tests.lisp doesn't use "hardcoded"
group id anymore
- remove patches:
* 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* dont-split-doc.patch
* sbcl-1.1.13-personality.patch: code was heavily refactored
- smaller spec clean ups
-------------------------------------------------------------------
Tue May 1 16:39:06 UTC 2018 - kasimir_@outlook.de
- Patch modified
* 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* dont-split-doc.patch
- Update to version 1.4.7
* enhancement: better handling of unknown keyword arguments (#1750466)
* enhancement: namestrings can now be computed for certain pathnames
that previously did not have namestrings because of #\. characters
in their name and/or type components.
* bug fix: compiling a SLEEP call with a float positive infinity
argument no longer causes an internal error (#1754081)
* bug fix: keyword arguments provided to a generic function with
EQL-specialized methods are checked more correctly (reported by Syll, #1760987)
- Changes in version 1.4.6
* enhancement: DISASSEMBLE on a symbol naming a macro will disassemble
the expander, not the code that traps attempted FUNCALL of the macro.
* enhancement: The sb-sprof contrib now provides an experimental
interface for accessing collected profiler data.
* enhancement: The instruction-level profiling of the sb-prof contrib
annotates the disassembler output more efficiently.
* optimization: improved dynamic-extent handling of nested variables.
- Changes in version 1.4.5
* minor incompatible change: building with/without the :sb-package-locks
feature is no longer an option. Package locks are always compiled in,
and removing :sb-package-locks from *features* will have no effect.
* enhancement: FIND-PACKAGE does not acquire a mutex
* enhancement: cheneygc can perform heap relocation on startup
* enhancement: in threaded builds, finalizers execute in a system-internal
thread so that a user thread which invokes GC is unblocked from performing
work as soon it returns from GC and invokes any post-GC hooks. As such,
it is more important than before to avoid assumptions about special
variable bindings in finalizers, even in single-threaded code.
* optimization: faster (funcall (or function symbol)) on x86-64.
- Changes in version 1.4.4
* bug fix: pathname accessors such as PATHNAME-DIRECTORY work on SYNONYM-STREAMs.
* bug fix: (pathname-{device,directory,name,type} ... :case :common) works
as expected. In particular MAKE-PATHNAME composed with the accessors
roundtrips properly when both use the same :case. (#1739906)
* bug fix: DIRECTORY no longer gets confused when the value
of *DEFAULT-PATHNAME-DEFAULTS* has a name or type component. (#1740563)
* bug fix: pattern pieces in pathname components are correctly escaped during unparsing.
* bug fix: DELETE-DIRECTORY no longer signals an error when the
directory is supplied as a pathname with name and/or type components
containing escaped characters. (#1740624)
* bug fix: weak hash-tables no longer cause GC time to scale
superlinearly (#1241771)
* bug fix: CANCEL-FINALIZATION operates in approximately constant
time per operation (#1587983)
* bug fix: big-endian MIPS systems now (mostly) work again (broken since 1.3.14.x).
* bug fix: backtrace from arg-count errors on systems other than
x86, x86-64, ARM, and ARM64 now works again.
* bug fix: backtrace from asynchronous interrupts on non-x86,
non-x86-64 systems should now be more reliable.
* enhancement: warnings and errors referring to bindings established
by LET, LET*, FLET and LABELS point to the offending form more accurately.
* enhancement: backtrace for invalid argument count produces the exact
supplied arguments including the extra ones on all platforms
(no longer just x86, x86-64, ARM, and ARM64).
- Changes in version 1.4.3
* enhancement: SLEEP respects deadlines established by SB-SYS:WITH-DEADLINE.
* bug fix: DECODE-TIMEOUT and operators accepting a timeout no longer signal
an error when called with an argument that is of type (real 0) but not (unsigned-byte 62) (#1727789)
* bug fix: fixed heap exhaustion bug when consing millions of small objects
* bug fix: sb-safepoint builds are now a lot less prone to deadlocks and
odd crashes (#1424031, #1268710)
* bug fix: argumentless CALL-NEXT-METHOD where specialized-to-T or
unspecialized parameters are mutated now uses the original (non-mutated)
parameter values (#1734771)
* bug fix: memory faults from lisp no longer use (thread-and-interrupt unsafe)
global storage for fault addresses (everywhere), and now have cleaner
backtraces (on x86 and x86-64). (#309068)
* bug fix: pathnames with a directory component of the form
(:absolute {:up,:wild,:wild-inferiors}) no longer fail to unparse. (#1738775)
* bug fix: more reliable signal handling on macOS.
- Changes in version 1.4.2
* minor incompatible change: SB-EXT:QUIT is no longer marked as deprecated
and behaves like SB-EXT:EXIT.
* enhancement: ASDF updated to 3.3.1. The ASDF release is dedicated to the
late Elias Pipping who put enormous amounts of work into it despite his
terminal illness. Thank you and rest in peace. (#1681201)
* enhancement: alien routines compiled with '-fsanitize=thread' and/or
'-fsanitize=memory' cause fewer false positives in error reporting.
* optimization: fewer instances of consing float constants at runtime.
* bug fix: a number of compiler bugs detected by Paul F. Dietz' randomized
tester. (#1731503, #1730699, #1723993, #1730434, #1661911, #1729639,
#1729471, #1728692)
* bug fix: better errors from NAMESTRING and friends on pathnames with
no namestrings. (#792154)
* bug fix: EQUAL and EQUALP compiler transforms were too confident in
deriving a result. (#1732277, #1732225)
* bug fix: FILL sometimes returned the underlying data vector rather
than the given array. (#1732553)
* bug fix: SEARCH returned the wrong answer in some cases. (#1732952)
* bug fix: the type (COMPLEX INTEGER) behaves more as specified by
Function TYPEP, which has stronger constraints than System Class
COMPLEX. (Reported by Eric Marsden, #1733400)
-------------------------------------------------------------------
Thu Nov 9 14:49:52 UTC 2017 - sweet_f_a@gmx.de
- Update to version 1.4.1
* optimization: faster foreign callbacks.
* enhancement: complex arrays can be stack allocated.
* enhancement: PROCESS-KILL now exists on win32 and PROCESS-PID
actually returns the PID.
* optimization: the register allocation method used by the
compiler when optimizing for speed is now faster for functions
with large bodies.
* bug fix: SB-INTROSPECT:ALLOCATION-INFORMATION works on
big-endian CPUs (fixes #490490 for real rather than by
disabling a test)
* bug fix: code objects and bignums of large enough size to be
placed on GC pages without any other object no longer cause
accidental copying during garbage collection. (gencgc only)
* bug fix: sb-fasteval failure with 0-argument lambdas (#1722715)
* bug fix: RUN-PROGRAM doesn't leak handles on win32 and
PROCESS-CLOSE doesn't crash. (#1724472)
- Changes in version 1.4.0
* minor incompatible change: DESTRUCTURING-BIND treats non-toplevel
() as nested empty pattern. This seems to be what the standard
mandates, so conforming code should not be affected.
* ehancement: (GC :GEN 7) with gencgc will zero-fill dead
pseudo-static objects so that they do not spuriously cause
reachability of objects that would have been otherwise dead.
* enhancement: PROCESS-STATUS now tracks stopped and continued
processes properly (also fixes #1624941, based on patch by Elias
Pipping).
* bug fix: INSPECT handles errors signaled while printing slot
values. (#454682)
* bug fix: DESCRIBE works on classes like it used to.
* bug fix: *LOAD-PATHNAME* and *LOAD-TRUENAME* are bound to
pathnames when processing a sysinit or userinit file
* bug fix: save-lisp-and-die is able to collect more garbage on
non-x86oid gencgc targets.
* bug fix: fixed out-of-bounds array read in optimized POSITION
on bit-vectors
* bug fix: signal emulation respects the 128-byte stack red zone
on x86-64 macOS.
-------------------------------------------------------------------
Fri Aug 11 10:21:35 UTC 2017 - sweet_f_a@gmx.de
- Update to version 1.3.20
* minor incompatible change: DEF{GENERIC,METHOD} no longer accept
some illegal lambda lists such as (defgeneric bar (foo &key
foo)) or (defgeneric baz (t)) that were accepted before.
* optimization: a valueless &AUX binding in a BOA constructor
does not force all slots reads in safe code to perform a full
type check.
* optimization: ATOMIC-PUSH and ATOMIC-POP generate better code
* bug fix: the low-level debugger would erroneously print - or
not print as the case may be - "(bad-address)" for some objects
depending whether the --dynamic-space-size argument was used at
Lisp startup
* bug fix: a DEFCONSTANT with a non non-eql-comparable object as
the value could cause miscompilation if that constant appeared
as the default expression for an &OPTIONAL binding
* bug fix: generic function lambda lists are now checked for
repeated and otherwise illegal entries. (#1704114)
* bug fix: setting gencgc_verbose = 1 could cause deadlock in
fprintf() depending on the platform's stdio implementation. The
relevant code has been changed to use snprintf() and write()
instead.
-------------------------------------------------------------------
Tue Jul 11 15:28:55 UTC 2017 - sweet_f_a@gmx.de
- Update to version 1.3.19
* enhancement: specialized arrays can be printed readably without using
*read-eval*
* enhancement: SB-DEBUG:PRINT-BACKTRACE truncates huge string arguments.
The full string remains available for inspection via (SB-DEBUG:ARG).
* bug fix: backtracing from several threads at once could fail
* bug fix: floating-point infinities could not be used as keys
in EQUALP hash tables. (lp#1696274)
* bug fix: random sb-fasteval failures. (lp#1642708)
* bug fix: align the stack in callback wrappers to defend against C
compiler over-aggressive use of SIMD. (lp#1697528)
* bug fix: don't try to find the class when reporting that a class does
not exist for a primitive type. (lp#1697226)
- Changes in version 1.3.18
* minor incompatible change: existing values of CFLAGS, ASFLAGS,
CPPFLAGS, and LINKFLAGS will be incorporated into C compiler
invocations when building from source.
* minor incompatible change: the result of WRITE-TO-STRING may be
a BASE-STRING if all characters written are of type BASE-CHAR.
* minor incompatible change: the broadcast stream with no output
streams is a singleton object. That object satisfies OPEN-STREAM-P
regardless of how many times CLOSE is invoked on it.
* enhancement: x86[-64] backends contain an experimental feature
which aids in demonstrating reachability of any object starting
from a tenured object or a thread stack by producing a proof
as a sequence of pointers to follow.
The file "tests/traceroot.test.sh" contains an example usage.
* enhancement: if the alien symbol "gc_coalesce_string_literals" is
set to 1 prior to SAVE-LISP-AND-DIE, then similar string constants
loaded from different fasl files may be collapsed to one object.
If the variable is set to 2, then additionally strings which are
STRING= in code resulting from COMPILE can be coalesced.
For instance, two functions returning the literal string "HI"
might return EQ strings after collapsing, which may be undesired
in a particular use. The flag pertains to gencgc only.
* enhancement: SXHASH values on pathnames are better distributed
* bug fix: MAKE-PATHNAME removes empty strings as components of a
directory, as is permitted: "Whenever a pathname is constructed
the components may be canonicalized if appropriate."
* optimization: various printer and FORMAT performance enhancements.
* bug fix: GET-FOREGROUND no longer fails in case all other interactive
threads exit (lp#1682671, reported by Syll)
* bug fix: RELEASE-FOREGROUND always removes the current thread from the
list of interactive threads. (lp#1682867, reported by Syll)
- Changes in version 1.3.17
* enhancement: memory overhead from the garbage collector's metadata
is reduced on 64-bit architectures; no change for 32-bit.
* enhancement: further garbage collector speedups affecting
pinned objects on conservative backends, and simple-vectors.
* enhancement: on Linux a custom handler for SIGSEGV can be called
for page faults outside of dynamic space by changing the C symbol
"sbcl_fallback_sigsegv_handler".
* bug fix: sb-cover does not lose source positions for AND/OR/COND.
* bug fix: random disassembler failures. (lp#1527931)
* The bundled sb-md5 contrib has been updated to release 2.0.4

- Update to version 1.3.16
* optimization: various small tweaks give around 5% faster garbage
collection
* bug fix: better detection of when an impossible code path does
not need a warning. (lp#1668619)
* bug fix: stronger attempts to disable position-independent
executable building. (lp#1668986, patch from Mark Wright)
* bug fix: OPEN :IF-EXISTS NIL signalled a condition on Windows.
(lp#1674437, reported by Jan Idzikowski)
- Changes in version 1.3.15
* minor incompatible change: the reader will when feasible create
new symbols using a BASE-STRING for the print name. Additionally,
string literals can favor the base-string type if desired, though
the default is to always return UTF-32 strings for compatibility.
A preference for base-string does not disable reading Unicode.
The choice is controlled via (SETF READTABLE-BASE-CHAR-PREFERENCE).
If Unicode was disabled at build time, this setting does nothing.
* enhancement: SBCL generates more debug information by default.
* enhancement: type errors provide context information, such as which
variable is being bound, which slot of which structure is being set.
* enhancement: if #+immobile-symbols is in build-time *FEATURES* (not
enabled by default), then symbols will never be moved in memory
except by SAVE-LISP-AND-DIE. Immobility has helpful implications for
code generation as well as interaction with foreign routines.
This feature can only be enabled if #+immobile-space is enabled.
* enhancement: undefined function errors can be restarted on x86-64, to
either retry calling the function again or call a user supplied function.
* enhancement: sb-ext:restrict-compiler-policy accepts an upper bound in
addition to a lower bound.
* enhancement: #+immobile-code improves the speed of function calling.
Some delay may be noticed when redefining an existing function
from a saved core file however.
* defaults change: sb-ext:*disassemble-annotate* default to NIL, due to its
poor reliability.
* new feature: SB-LINKABLE-RUNTIME, allowing linking with extra object
files to help with delivery of executables. (Thanks to François-René
Rideau)
* bug fix: data race in GENTEMP fixed - it can no longer return the
same interned symbol to multiple threads if called concurrently
* bug fix: interrupting LOADing of FASLs does not leave functions without
source locations. (lp#540276)
* bug fix: DYNAMIC-EXTENT-declared results of NOTINLINE local functions were
treated as if they were actually stack allocated (lp#1659964)
* bug fix: correctly handle the case of a non-local exit within a function
terminating the extent of dynamic-extent, dynamic-bound variables in the
presence of multiple-values (lp#1655011)
* bug fix: handling of SB-SYS:WITH-PINNED-OBJECTS in the interpreters (both
sb-eval and sb-fasteval) now actually pins objects on gencgc.
* bug fix: AVX registers are preserved during exceptions on x86-64 macOS.
* bug fix: (directory "SOMETHING/*/**/MORE") is no longer equivalent to
(directory "SOMETHING/**/MORE")
* bug fix: better console IO on Windows (lp#1660906)

-------------------------------------------------------------------
Wed Feb 22 10:56:25 UTC 2017 - sweet_f_a@gmx.de
- Update to version 1.3.14
* minor incompatible change: the SB-PCL walker no longer recognizes
macros expanding into a DECLARE expression. This is not a language change,
since ANSI forbids such usage (X3J13 issue DECLARE-MACROS:FLUSH).
* enhancement: for several macros such as MULTIPLE-VALUE-{BIND,SETQ}, COND,
DO{,*,LIST}, {RESTART,HANDLER}-{BIND,CASE}, *CASE, conditions signaled
during macroexpansion point to the form that caused the problem more
accurately.
* enhancement: the "--noinform" command-line option inhibits output from
save-lisp-and-die in addition to removing the startup banner.
* bug fix: PROCESS-KILL failed to return errno if the system call failed
* optimization: slightly more comprehensive treatment of the keyword
arguments to MAKE-ARRAY in compiler transformations.
- Changes in version 1.3.13
* enhancement: SET triggers package locks on undefined variables.
(lp#1645152)
* enhancement: new Windows specific option to run-program, :escape-arguments
(lp#1503496)
* enhancement: recompiling a MAKE-INSTANCE form with an initarg :INITARG
CONSTANT where CONSTANT names a constant variable picks up the new value
of CONSTANT in case it has been redefined. (lp#1644944)
* optimization: faster TYPEP on undefined at compile-time types and upcoming
class definitions. (lp#1082967)
* optimization: memory consumption of each STANDARD-OBJECT instance is
reduced by 2 words if the compact-instance-header feature is enabled.
* optimization: CONDITION instances are quicker to allocate.
* optimization: unoptimized calls to FILL on specialized vectors are now
just as fast as T vectors.
* bug fix: get-timezone returns corret DST on 64-bit Windows. (lp#1641058)
* bug fix: cross reference information in fasls is no longer incompatible
between different cores (lp#1648186)
- Changes in version 1.3.13
* enhancement: on x86-64, compiled functions loaded from fasl files
can not be moved, but can be freed, by GC. Additionally, COMPILE will
produce immobile code if SB-C::*COMPILE-TO-MEMORY-SPACE* is set to
:IMMOBILE. (Caution: the flag is experimental and subject to change.)
The benefits are better physical separation of code from data,
and potentially easier examination of live images by external tools.
* enhancement: the docstring for SAVE-LISP-AND-DIE has been amended to
say that the :ROOT-STRUCTURES parameter is not meaningless on gencgc,
depending on the platform.
* bug fix: calling a named function (e.g. a DEFUN) concurrently with
redefining that same function could lead to execution of random bytes.
* bug fix: yes-or-no-p accepts formatter functions (lp#1639490)
* bug fix: better handling of exceptions on macOS.
- rebase 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
- remove sbcl-cast.patch (it's upstream now)
-------------------------------------------------------------------
Thu Nov 3 11:56:02 UTC 2016 - sweet_f_a@gmx.de
- Update to version 1.3.11
* minor incompatible change: SB-EXT:*INTEXP-MAXIMUM-EXPONENT* is
removed.
* enhancement: TRACE ... :REPORT {TRACE,NIL} now work as
advertised in the documentation string (based on patch by
Patrick Stein)
* enhancement: support unboxed signed-word structure slots on
x86, x86-64 and ARM64. (lp#377616)
* optimization: faster logical bit-array operations on
multidimensional arrays.
* optimization: better GC performance in the presence of many
threads. (patch by Ilya Perminov, lp#1339924)
* optimization: multiple-value-call is optimized with multiple
argument forms, not just one. (lp#753803)
* bug fix: MAKE-ALIEN-STRING returns the number of allocated
bytes as a second value as advertised (reported by Johann
'Myrkraverk' Oskarsson)
* bug fix: when TO-READTABLE is supplied to COPY-READTABLE, it
will contain only the macros in FROM-READTABLE and no others.
(lp#1631506)
* enhancement: gencgc has been modified for x86-64 on Linux and
macOS to a support mark-and-sweep as well as the traditional
copying strategy. It is conceivable that some applications
might be adversely affected. Please see ':immobile-space' in
'base-target-features.lisp-expr' for further details, and
possible reasons to disable this feature.
* enhancement: x86-64 supports shrinking the fixed overhead in a
structure from 2 words to 1 word, reducing memory consumption
in applications which create many small structures.
- Changes in version 1.3.10
* enhancement: more compact low-level error signaling code
* enhancement: more compact encoding of cross-reference
information
* optimization: faster out of line fixnum-float comparisons.
* optimization: filling a known simple-vector with a constant
value is about as fast in unoptimized code as in code compiled
with (SPEED 3), and the x86-64 implementation is able to use
SSE instructions.
* bug fix: correctly handle the case of a non-local exit within a
function terminating the extent of dynamic-extent functions and
variables in the presence of multiple-values (lp#1563127)
* bug fix: restore builds on the latest OSX with the latest
Xcode (lp#1470996)
- Changes in version 1.3.9
* minor incompatible change: NAMESTRING prefers to return a
BASE-STRING instead of (ARRAY CHARACTER (*)) when possible.
* enhancement: cached make-instance/allocate-instance
constructors can now get garbage collected.
* optimization: better performance for some unoptimized
operations on complex numbers.
* bug fix: using the options :LOCAL-NICKNAMES and :LOCK in the
same DEFPACKAGE form no longer signals a bogus error
- Changes in version 1.3.8
* minor incompatible change: the system now understands that the
CONDITION type is disjoint with many other system types.
* minor incompatible change: argument types in condition report
functions are now declared (in combination with the above
change, this can result in early detection of erroneous code).
* enhancement: simple arrays of any rank can be stack-allocated
on platforms supporting stack allocation of vectors.
* optimization: improved type derivation for FIND, POSITION,
COUNT, SEARCH, MISMATCH and other array and sequence functions.
* optimization: ALLOCATE-INSTANCE is now as fast as
MAKE-INSTANCE.
* optimization: more efficient CHANGE-CLASS.
* bug fix: versions of getresuid() and getresgid() in SB-POSIX no
longer cause memory faults, and should work properly
(lp#1603806, reported by Kieran Grant)
* bug fix: handle ENOENT from getprotobyname() (lp#1596043,
reported by Stephen Hassard)
- remove upstream patches:
* 0001-Handle-ENOENT-from-getprotobyname.patch
* 0002-sb-posix-Fix-getresuid-and-getresgid.patch

Wed Sep 30 10:32:41 UTC 2015 - kgronlund@suse.com
- Update to version 1.2.15
+ new feature: DEPRECATION declaration for functions, variables
and types causes {EARLY,LATE,FINAL}-DEPRECATION-WARNING to be
signaled when subject of the declaration is used. Integrated
with DESCRIBE, DOCUMENTATION and
SB-CLTL2:{VARIABLE,FUNCTION}-INFORMATION. Documented in the
"Deprecation" section of the manual.
+ enhancement: ASDF updated to 3.1.5. (#1476867)
+ enhancement: definitions within PROGN get proper source
locations when compiled (needs latest Slime to take advantage
of this). (#1473147)
+ enhancement: source locations for DEFCLASS slots now point
directly to the slot definitions, not the whole DEFCLASS form.
+ bug fix: better source location in the presence of quoted
forms. (#1370561)
+ bug fix: better source locations inside backqoute. (#1361502)
+ bug fix: HANDLER-BIND requires that the handler-function be a
function designator at the time of binding establishment.
(#1480679)
+ bug fix: inlined functions surrounded by nested macrolets are
properly inlined. (#309123)
- Changes in version 1.2.14
+ minor incompatible change: The name of a compiled anonymous
lambda as returned by the third value of
FUNCTION-LAMBDA-EXPRESSION can have a lambda-list-like list
following the introductory LAMBDA that is not in general a
syntactically valid lambda list. Specifically, it won't retain
default values, supplied-p variables, or &KEY or &AUX bindings.
+ enhancement: DESTRUCTURING-BIND has been totally reimplemented
from scratch to address a handful of performance and correctness
issues. Some minor behavioral differences exist regarding order of
evaluation of default forms for unsupplied &OPTIONAL and &KEY
arguments when nested destructuring patterns are involved.
(#707556, #707573, #707578, #708051)
+ enhancement: DEFCONSTANT and DEFSTRUCT respect package locks.
(#1186238, #1036716)
+ enhancement: sb-unicode:normalize-string has a new optional
argument, FILTER, a callback which controls which decomposed
characters are collected. Useful for stripping away diacritics
more efficiently.
+ bug fix: (TYPE-OF ARRAY) for a non-simple array is subject to
change after a call of ADJUST-ARRAY. (#1333731)
+ bug fix: Dynamic-extent allocation with a loop between
allocating a value and the start of its environment no longer
discards the allocated data when the loop is taken. (#1472785)
+ bug fix: Variable-reference elimination no longer generates
incorrect code under certain circumstances. (#1446891)
+ bug fix: variables with EQL types are no longer treated as
constants by VOPs, which caused problems with closures being
allocated for such variables, but they remained unused. (#1390149)
+ bug fix: Windows installer generates registry key name
correctly. (#1476447)
-------------------------------------------------------------------
Tue Jul 14 09:58:58 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.13
* Incompatible change:
+ on success, TRY-SEMAPHORE and WAIT-ON-SEMAPHORE return the new
count
* Enhancement:
+ WAIT-ON-SEMAPHORE accepts a decrement parameter
+ JOIN-THREAD allows distinguishing timeout vs.
abort in all situations
+ On Windows DBG_PRINTEXCEPTION_C is handled and its
message is printed. (#1437947)
* Bug-fix:
+ TRUENAME works properly on broken symlinks presented
as directories. (#1458164)
+ Inlined DPB and DEPOSIT-FIELD don't interfere with
left-to-right order of argument evaluation. (#1458190)
+ (SETF (LDB (BYTE 1 2 JUNK) X) 0) is rightly rejected.
+ DEFSETF lambda lists should not permit argument
destructuring.
+ calls to (SETF SLOT-VALUE) on a missing slot would in
certain situations incorrectly return the result of a
SLOT-MISSING method instead of always returning the new
value. (#1460381)
+ a DEFMACRO occurring not at toplevel and capturing
parts of its lexical environment (thus being a closure)
caused expressions involving the macro name to cause corruption
in the pretty-printer due to faulty introspection of the lambda
list of a closure.
+ out of line MAP/MAP-INTO check that the results produced by the
function are of the matching sequence type. (#1459581)
+ pretty-printing of '(LET `((,X ,Y)) :B) is handled correctly.
-------------------------------------------------------------------
Wed Jun 17 06:58:19 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.12
* Minor incompatible change:
+ the SB-C::*POLICY* variable is no longer a list. Code which
manipulated it as such (including but not limited to non-bundled
releases of ASDF) will need to be revised.
* Enhancement:
+ The input stream for COMPILE-FILE implements STREAM-LINE-COLUMN.
+ EVAL errors that occur by way of LOAD report the starting line
and column number of the erring toplevel form. (#565247)
* Optimization:
+ Better MAP and MAP-INTO on known vector result types.
* Bug fix:
+ Read/modify/write macros accessing a place which is a composition
of CAR+CDR operations, such as (SHIFTF (CADR X) (ELT V 0)), do
not access subforms more than once. (#1450968)
+ Short form of DEFSETF no longer allows trailing junk.
+ DEFINE-MODIFY-MACRO respects the provisions of CLHS 5.1.3
regarding argument evaluation order. (#1452539)
+ POP works as specified in CLHS if the setter for its argument has
a side-effect on the existing CAR value. (#1454021)
+ Reading "#()" with a positive numeric argument signals a reader
error. As specified, reading "#1()" has undefined consequences,
so correct portable code should be indifferent to this.
(#1252100)
+ Malformed reader conditionals such as "(#-no-such-feature)"
and "(#+sbcl)" no longer parse as NIL. (#1454400)
-------------------------------------------------------------------
Sat May 2 22:36:33 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.11
* Enhancement:
+ SET-PPRINT-DISPATCH will warn when given an expression in
which any part is unrecognizable as a legal type-specifier.
The dispatch table will be altered, but the new entry is
disabled. Subsequent type-defining forms will cause
pprint-dispatch tables to re-examine whether any disabled
entries should be enabled. (lp#1429520)
+ Loading code containing calls to a deprecated function will,
under most circumstances, signal warnings similar to compiling
such code. The usual caveat holds about not detecting calls
through a computed name, as in (funcall
(intern "DEPRECATED-FUN" "SB-EXT")).
+ (SB-EXT:COMPILE-FILE-LINE) is a new macro that expands to a
constant (VALUES integer integer) indicating the source
line/column from which it was read, intended for logging Lisp
runtime errors in a style similar to that afforded by the C
preprocessor __LINE__ macro. Similarly
(SB-EXT:COMPILE-FILE-POSITION) returns a position in characters.
+ improved source locations for VOPs, alien types and declarations.
* Bug fix:
+ Functions in :FINAL deprecation have the correct docstring.
No visible change, as no such functions presently exist.
(lp#1439151)
+ (SETF (FDEFINITION this) (FDEFINITION OTHER)) signals an error
if OTHER names either a macro or special-operator. (lp#1439921)
- Rebase all patches.
-------------------------------------------------------------------
Wed Apr 1 10:24:36 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.10
* One thing that is not mentioned in the release notes, but which
has been exercising developers recently, is a warning for the near
future: some interfaces which are currently in "early" deprecation
status (and so are emitting style-warnings at compilation-time)
will in the next release cycle or two start emitting full warnings,
either at compilation time or at load time. Particular interfaces
signalling warnings causing problems to some users include:
SB-EXT:QUIT, and the SB-THREAD:SPINLOCK API. If anyone is using
those, now is the time to update to SB-EXT:EXIT and
SB-THREAD:MUTEX respectively. (See also the "Deprecated Interfaces"
chapter in the manual).
* minor incompatible change:
+ all SOCKINT::WIN32-* functions have been deprecated with
EARLY deprecation state
+ performing introspection via the system-internal SB-INT:INFO
function could expose that :TYPE :TRANSLATOR is not
necessarily a function, as it always was before. (Affects
swank-fancy-inspector)
* enhancement:
+ The value of SXHASH on bit-vectors of length equal to the
word size now depends on the vector's contents instead of
being constant; its value on bit-vectors of length divisible
by the word size now depends also on the contents of the
vector's last word.
* bug-fix:
+ sb-bsd-sockets on win32 uses proper C function declarations.
(lp#1426667)
+ A new dead code elimination phase removes dead code loops
that confuse stack analysis. (lp#1255782, lp#308914)
+ A toplevel form which was simple enough to bypass the main
compiler in COMPILE-FILE, and which contained an empty SETQ or
PROGN would produce an invalid fasl file. (lp#1427050)
+ The compiler no longer signals an internal error when
encountering invalid FUNCTION forms like (function 1)
+ express proper dependencies in the ASDF contrib, to support
systems where make runs in parallel. (lp#1434768; thanks to
Nikhil Benesch)
- Apply disable-localport-bsd-sockets-test.patch for all since
without it random build failures are happening in OBS even though
local builds are just fine without disabling the bsd-socket-tests
-------------------------------------------------------------------
Sat Feb 28 23:05:42 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.9
* Bug Fix:
+ minor incompatible change and bug fix: unboxed numeric
constants on x86oids are arranged in memory differently, and
the disassembler does not show them separately in DISASSEMBLE,
but does if DISASSEMBLE-CODE-COMPONENT is used. (lp#1421987)
+ DEFCLASS handles cyclic {super,meta}class relations better
(lp#1418883)
+ compiler no longer signals an error when compiling certain
function calls. (lp#1416704, lp#404441, lp#1417822, lp#1234919)
+ compiler doesn't stumble on a LOGIOR transform.
(lp#1389433)
+ more robust debugger and backtraces. (lp#1413850,
lp#1099500, lp#1412881, lp#945261, lp#1419205, lp#1409402)
+ files larger than 4GB can now be compiled.
+ x86 truncated results from 64-bit foreign functions to
32 bits.
+ file-position didn't work on large files on win32.
(lp#1271545)
+ callbacks from foreign threads can work without enabling
sb-safepoint.
+ sb-introspect:function-lambda-list works properly on
interpeted macros. (lp#1387404)
+ ADJUST-ARRAY properly handles non-adjustable arrays.
(lp#886418)
+ compiler no longer fails to dump a multidimensional
array constant involving a circular reference to itself
+ conditional and nested DX allocation no longer confuse
the compiler in STACK analysis. (lp#1044465)
+ sb-rotate-byte constant folding bug fixed. (lp#1423682)
* Optimization:
+ The compiler's treatment of type specifiers makes
it slightly faster and more memory-efficient. Portable code
should be indifferent to this change, however, users of
SB-INTROSPECT:FUNCTION-TYPE might notice that (MEMBER T NIL)
and (MEMBER NIL T) are both internally collapsed to the former,
so that the latter can never be obtained as part of an FTYPE.
+ a TYPEP call in which the second argument is not
a QUOTE form but nevertheless recognized as a compile-time
constant might open-code the test. One scenario for this involves
backquote, such as (TYPEP x `(my-type ,some-arg)). Code which relied upon
deferring until runtime should declare (NOTINLINE TYPEP).
[Due to the sematic constraints of DEFTYPE etc in in CLHS
3.2.2.3, code requiring delayed evaluation could be unportable though.]
* Enhancement:
+ unused variables at the top-level are now reported.
(lp#492200)
-------------------------------------------------------------------
Mon Feb 2 08:28:20 UTC 2015 - toganm@opensuse.org
- The release (source) tarball of sbcl-1.2.8 contained an error in
the build script, which in some circumstances (chiefly when /bin/sh is
bash) would lead to the sbcl built from that tarball to have a
lisp-implementation-version of "-dirty".
-------------------------------------------------------------------
Sat Jan 31 20:05:23 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.8
* Enhancement:
+better error and warning messages. (lp#1314767,
lp#736383)
+ backtrace for invalid argument count produces the
exact supplied arguments including the extra ones, on x86,
x86-64 and ARM.
+ STYLE-WARNING is signaled for DEFSTRUCT accessors which
are used before the structure is defined; similarly for the
predicate.
* Optimization
+ FORMAT NIL with only ~a and string arguments is transformed
into CONCATENATE.
+ POSITION and FIND when inlined into code that is compiled
with qualities of safety < 2 and speed > space will no longer
signal an error on circular lists, but will potentially loop
forever if given no :END constraint. As was always the case,
calls that are not inlined are safe regardless of lexical
policy.
* Bug Fix:
+ CLOS methods compiled with (OPTIMIZE (DEBUG 0))no longer
cause debugger failure when printing a backtrace
+ more resilience to deleted code. (lp#1308328, lp#1390544)
+ the CLHS example of MAKE-LOAD-FORM involving TREE-WITH-PARENT
did not work, and now it does.
-------------------------------------------------------------------
Thu Jan 8 11:59:20 UTC 2015 - toganm@opensuse.org
- Update to version 1.2.7
* Optimization:
+ returning constant values refers to preboxed
constants more reliably. (lp#1398785)
* Enhancement:
+ STYLE-WARNING is produced if a compiler-macro is
defined for a function after at least one ordinary (not inlined)
call to that function was compiled, indicating a likely
compilation order problem. Likewise a warning ensues if a call
is compiled to a function that is subsequently proclaimed INLINE.
+ always lose() when something goes wrong while saving a core
(instead of just printing an error on stderr in some situations).
+ frames in the debugger are now restartable by default.
* Bug Fix:
+ restore error handling on Windows x86.
+ MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
at compile-time when possible. (lp#330299)
+ parsing of malformed type specifiers no longer results in a
memory-fault-error.
+ LOOP properly destructures nested lists in WITH.
+ MACROEXPANDing the redefinition of an alien structure type no
longer signals the wrong error.
+ PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).
-------------------------------------------------------------------
Tue Dec 2 11:48:51 UTC 2014 - toganm@opensuse.org
- Update to version 1.2.6
* enhancement:
+ SERVE-EVENTS uses the poll() system call in lieu
of select() if the OS has the former. Previously poll() was
used only if waiting on exactly one file descriptor.
+ efficiency of access to untagged structure slots
is improved on x86-64, and the order of slots in memory is
exactly as specified by defstruct, simplifying use of
structures as arguments to foreign calls.
* bug fix:
+ SB-DEBUG:ARG now works in all TRACE options which
evaluate forms. (lp#1357826)
+ GC memory corruption during internal memory handling.
+ duplicate effective-slot-definition objects as compared
by EQ on name could be present in CLASS-SLOTS of a class whose
metaclass was structure-class or condition-class. (lp#1049423)
+ HANDLER-BIND with empty bindings works again; regression in
1.2.5. (lp#1388707)
+ ATOMIC-INCF works on structure slots in interpreted code.
(lp#1381867)
+ MAKE-ARRAY properly handles character types like (eql
#\a) and (member #\a #\c). (lp#1392068)
+ bug fix: READ sometimes accidentally preserved a whitespace
character after a token when it should not have. (lp#327790)

obsolete patch
-------------------------------------------------------------------
Wed Nov 5 08:17:38 UTC 2014 - toganm@opensuse.org
- Update to version 1.2.5
* Enhancement
+ sb-bsd-sockets now has basic support for IPv6
+ An sb-unicode package has been added, containing
many functions related to handling Unicode text
+ The reader now normalizes symbols to Normalization
Form KC (NFKC). This behavior can be disabled with
SB-EXT:READTABLE-NORMALIZATION
+ enhancement: a style-warning is signaled if OPTIMIZE
declarations multiply specify a quality with differing values.
(lp#310267)
* Bug fix:
+ conservatively pointed to pages wipe out unused dwords
so that they cannot act as false roots in turn.
+ the walker's handling of lexical variable and
symbol-macro bindings is improved (lp#375326, lp#1368305)
+ HANDLER-{BIND,CASE} no longer drop into ldb when a
clause contains an undefined condition type; regression
in 1.1.19( lp#1378939)
+ in interpreted code, inequality predicates did not
type-check arguments that weren't examined, and a 1-argument use
of MIN or MAX accepted a complex number. (lp#1373702)
+ APROPOS and APROPOS-LIST handle inherited symbols correctly.
(lp#1364413, thanks to Zach Beane)
-------------------------------------------------------------------
Sun Aug 31 18:24:15 UTC 2014 - toganm@opensuse.org
- Update to version 1.2.3
* Enhancement:
+ DOCUMENTATION works on instances of FUNCALLABLE-STANDARD-CLASS
+ ASSERT reports arguments of calls to lexical functions in
additional to global functions.
+ ASDF updated to 3.1.3
+ UIOP can be loaded without ASDF.
* Bug Fix:
+ Some methods on CHANGE-CLASS did not finalize the new class
before accessing its class-precedence list.
+ CHANGE-CLASS no longer fails on unbound slots in the source
object.
+ CHANGE-CLASS signals an appropriate error when the destination
class is a FORWARD-REFERENCED-CLASS.
+ CHANGE-CLASS no longer signals bogus TYPE-ERRORs for slots for
which initargs have been supplied.
+ saving cores on ARM was broken since the introduction of GENCGC.
(lp#1349795)

-------------------------------------------------------------------
Mon Jul 28 13:48:15 UTC 2014 - toganm@opensuse.org
- Update to version 1.2.2
* incompatible change: the #\` ("backquote") reader macro was
reimplemented to support robust pretty-printing. Reading a form
involving #\` produces an invocation of the QUASIQUOTE ordinary
macro which may contain subforms that are not lists. Code that
unportably attempts operations on un-evaluated forms resulting
therefrom, e.g. (SUBST a b (read-from-string "`(x (,y))"))
might generate incorrect results and/or errors.
* Enhancement:
+ support for GNU/kFreeBSD x86.
+ ATOMIC-INCF and ATOMIC-DECF can operate on (CAR
x), (CDR x) and DEFGLOBAL variables of type fixnum.
+ enhancement: arithmetic constant reduction is now performed on
defconstant constants too. (lp#1337069).
* Bug Fix:
+ certain ftype proclamations containing &optional t &rest t no
longer cause subsequent definitions to signal bogus
style-warnings.
+ #\Bell and #\Bel now read to different characters. (lp#1319452).
+ CAS SYMBOL-VALUE on locally special variables didn't work.
(lp#1098355)

- Update to version 1.2.1
* Enhancement
+ GENCGC is enabled on ARM.
+ better error reporting for invalid calls to local
functions.
+ support for GNU/kFreeBSD distributions.
(lp#1079954, thanks to Christoph Egger)
+ experimental support for threads on NetBSD/x86-64.
(thanks to Robert Swindells)
+ support for DragonFly BSD. (lp#1292845, thanks to
Vasily Postnicov)
* Bug Fix:
+ TYPE-OF must not return AND/OR/NOT expressions. (lp#1317308)
+ accessing NIL arrays stopped producing errors. (lp#1311421)
+ DISASSEMBLE no longer prints unwanted stuff. (lp#1251861)

+ silence compiler notes from the SEARCH transform.
(lp#1071310)
+ array type intersection handles T and unknown element types
correctly. (lp#1258716)
+ fix a corner case in array type unparsing that would result in
misleading translations from our internal type representation.
+ array-rank now sees through union and intersection types.
(lp#1310574)
+ when DECLARE expressions are in the wrong place, be careful not
to attempt to evaluate the subforms. (lp#573747; thanks to Roman
Marynchak)
+ misplaced and missing declarations in DEFTRANSFORM. (lp#1066451)
+ FBOUNDP returned NIL for a class of incorrect function names
instead of signaling an error. (lp#1095483)
+ fix a compile-time AVER in regalloc: lifetime analysis used to
(rarely) introduce duplicate conflict markers in a single
TN/block pair. (lp#1327008)

* Optimization
+ COERCE is now more effecient for more cases when
the type is known at compile-time. (lp#1309815)
* Bug fix
+ correctly inherit condition initforms. (lp#1300904)
+ properly pprint literal functions inside nested lists.
(lp#1300716)
+ more-correctly handle array-type unity (broken for
ages, causing compilation problems since 1.1.13.x due to
smarter TYPEP type propagation reported by jasom in #lisp).

-------------------------------------------------------------------
Sat Mar 1 18:14:29 UTC 2014 - toganm@opensuse.org
- Update to version 1.1.16
* Enhancement
+ SB-EXT:DEFINE-LOAD-TIME-GLOBAL. (lp#1253688)
+ Loading fasls with symbols from an undefined package includes
the name of the symbol in the error message.
* Bug fix
+ problems when redefining classes and doing TYPEP on classes
concurrently. (lp#1272742)
+ fixes to the x86-64 XCHG instruction:
- it was misencoded when used with RAX, R8-R15 registers.
(reported by Eric Marsden)
- it was misencoded when used to exchange EAX with itself.
- the disassembler wrongly printed XCHG RAX, R8 and the
corresponding 32- and 16-bit variations as NOP.
+ the disassembler outputs source annotations in the right place
and no longer randomly drops some of them. (lp#1249205)
+ fix commutative-arg-swap from introducing undumpable structures
into code, prevent code with errors from being compiled.
(lp#1276282)
+ pathnames with :back in their directory component are
succeffully resolved.

to wrap functions around. (lp#309086)
-------------------------------------------------------------------
Fri Jan 31 07:53:27 UTC 2014 - toganm@opensuse.org
- Update to version 1.1.15
* New feature:
the iterative spilling/coloring register allocator developed
by Alexandra Barchunova during Google Summer of Code 2013 is
now merged in. By default, it only activates for functions that
optimize with (speed 3) and (> speed compilation-speed), but
setting sb-regalloc:*register-allocation-method* to :iterative
forces its execution. The previous behaviour can be obtained by
instead setting that variable to :greedy.
* Optimization:
+ make-array with known element-type and unknown dimensions is
much faster.
+ make-array with unknown element-type is faster as well.
(lp#1004501)
* Enhancement:
+ reduced conservativism on GENCGC platforms: conservative roots
must be valid-looking tagged pointers or point within a code
object, not merely point to within the allocated part of a
page, in order to pin a page.
+ support for "Mac Roman" external format.
+ encapsulation of named generic functions now happens without
altering the identity of the function bound to the name.
* Bug fix:
+ modular arithmetic optimizations do not stumble on dead branches
with bad constants. (reported by Douglas Katzman)
+ CLISP can be used again as a cross-compilation host.
(Thanks to Vasily Postnicov, lp#1261451)
+ run-program crashed with :directory nil. (lp#1265077)
-------------------------------------------------------------------
Sat Nov 30 17:44:30 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.14
* Optimization:
+ complicated TYPEP tests are less opaque to the
type propagation pass. (lp#1229340)
+ [N]BUTLAST perform a single pass over the list.
(lp#1245697)
+ EQUALP on structures with raw slots (double-float/complex)
no longer conses and is faster.
+ RESTART-CASE expands to more compact code.
Thanks to Jan Moringen. (lp#1249055)
* Enhancement:
+ Top-level defmethod without defgeneric no longer
causes undefined-function warnings in subsequent forms.
(lp#503095)
+ run-sbcl.sh is usefully handled by rlwrap. Thanks
to William Cushing. (lp#1249183)
+ new function SB-EXT:ASSERT-VERSION->= accepts a version
specification (multiple integer arguments) and signals a
continuable error if the current SBCL version is lower (older)
than the specification. (lp#674372)
+ better ARRAY-RANK result derivation. (lp#1252108)
* Bug fix:
+ EQUALP now compares correctly structures with raw slots larger
than a single word.
+ OPEN reports a more meaningful error when an existing file is
opened for output with :if-exists :new-version.Thanks to
Philip Munksgaard. (lp#455381)
+ DEFSTRUCTs with NIL as a slot name no longer cause strange
CLOS-related errors. (lp#633911)
-------------------------------------------------------------------
Thu Oct 31 13:50:22 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.13
* Optimization:

values. (lp#309443)
+ other improvements to SXHASH:
- use the whole of the positive-fixnum range for SXHASH of
fixnums
* Enhancement:
+ The error message when calling an undefined alien function
includes the name of the function on x86-64.
+ sb-ext:run-program now supports :environment on Windows.
+ ASDF is no longer required to load contribs at runtime.
(lp#1132254)
+ when called with a symbol, FIND-RESTART no longer calls
COMPUTE-RESTARTS, making it faster and cons less (lp#769615)
+ FIND-RESTART and COMPUTE-RESTARTS handle huge restart
clusters better in some cases
+ SOME/ANY/other quantification higher-order functions no
longer cons. (lp#1070635)
* Bug fix:
+ forward references to classes in fasls can now be loaded.
(lp#746132)
+ don't warn on a interpreted->compiled function redefinition
from the same location. (patch by Douglas Katzman, lp#1042405)
+ Create vectors of proper internal length when reading literal
vectors from FASLs. (Reported by Jan Moringen)
+ COMPILE can now succefully compile setf functions.
(Reported by Douglas Katzman)
+ run-program performs more correct escaping of arguments on
Windows. (lp#1239242)
+ function-lambda-expression on generic functions returns the
actual name.
+ (the [type] [constant]) now warns when [constant] matches
[type] except for the number of values. (Reported by Nathan
Trapuzzano on sbcl-help)
+ signal errors in required cases of slot-definition
initialization protocol. (lp#309072)
+ run-sbcl.sh works better in the presence of symlinks on OS X.
(thanks to Stelian Ionescu, lp#1242643)
+ when given a restart object, FIND-RESTART checks whether the
restart is active and, when a condition is supplied, whether
the restart is associated to a different condition (lp#774410)

Tue Oct 1 09:27:53 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.12
* Enhancement:
+ Add sb-bsd-sockets:socket-shutdown, for calling
shutdown(3). lp#1207483
+ document extensible sequences. lp#994528
* Optimization:
+ EQUAL and EQUALP transforms are smarter. lp#1220084
+ CHAR-EQUAL is faster for constant and base-char arguments.
* Bug fix:
+ probe-file now can access symlinks to pipes and sockets in
/proc/pid/fd on Linux. (reported by Eric Schulte)
+ SBCL can now be built on Solaris x86-64.
+ Floating point exceptions do not persist on Solaris anymore.
+ (setf . a) is pprinted correctly
+ handle compiler-error in LOAD when it's not run from inside EVAL.
lp#1219601
+ SB-GMP:MPZ-POW no longer segfaults given a non-bignum base.
+ space allocation of result bignums in SB-GMP is more accurate.
lp#1206191
+ sb-safepoint can now reliably handle signal interruptions of
foreign code. lp#1133018
+ the compiler-macro for MAKE-INSTANCE when emitting "fallback"
constructors no longer fails to merge actual and default
initargs lp#1179858
+ the compiler-macro for MAKE-INSTANCE when emitting "fallback"
constructors handles non-KEYWORD initialization arguments more
correctly.
+ loading the SB-SIMPLE-STREAMS contributed module no longer
clobbers FILE-NAMESTRING. lp#884603
+ class definitions with CPLs inconsistent with their metaclasses
are less likely to destroy the object system's integrity.
lp#309076
+ restart clause parsing in RESTART-CASE is more in line
with the standard. lp#1203585
+ silence a note from RESTART-CASE under high-SPEED optimization
settings. lp#1023721
+ getting the order of arguments to
SB-MOP:SET-FUNCALLABLE-INSTANCE-FUNCTION wrong produces a
sensible error rather than a failed AVER.
+ Parsing of &optional/&key/&rest arguments now never overwrites
arguments during copying on x86 and x86-64; it may still happen
on other platforms when there are more fixed arguments than
stack slots.
-------------------------------------------------------------------
Wed Aug 28 15:04:18 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.11
* Enhancement:
+ support building the manual under texinfo version 5 lp#1189146
* Bug fix:
+ undefined function errors are now properly reported on
PPC and MIPS. (regression since 1.1.9)
+ (funcall (function X junk)) didn't causes an error
when X had a compiler macro.
+ signal a warning when defining a setf-function when a
setf-expander is already present.
+ improved threading on PPC.
+ Streams were flushed even when there was one byte
still left in the buffer. (lp#910213)
+ OPEN handles correctly when :if-exists and
:if-does-not-exist are either NIL or :ERROR.
-------------------------------------------------------------------
Mon Jul 29 07:11:41 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.10
* Enhancement:
+ ASDF has been updated to 3.0.2.
* Optimization:
+ stack frames are packed more efficiently on
x86oids, which ought to reduce the frequency of Methuselahn
conservative references (it certainly helps with gc.impure.lisp
/ BUG-936304 on x86).
+ on x86 and x86-64, integer negation forms like
(- * x) are now recognized in modular arithmetic contexts, and
compile to native negate, rather than going through bignums only
to keep the low bits.
* Bug fix
+ Compiling potential modularic arithmetic forms does
not cause type errors when some integer types lack lower or upper
bounds. (lp#1199127)
+ Non-trivial modular arithmetic forms are always cut to
the right bitwidth before being used in a non-modular context.
(lp#1199428)
+ Multiple catch/unwind blocks in a single function are now
allocated in the right stack order on win32. (lp#1072739)
-------------------------------------------------------------------
Thu Jul 4 11:18:17 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.9
* New feature:
+ the contrib SB-GMP links with libgmp at runtime to speed up
arithmetic on bignums and ratios. (contributed by Stephan
Frank)
* Enhancement:
+ disassemble now annotates some previously
missing static functions, like LENGTH.
+ SB-EXT:PRINT-SYMBOL-WITH-PREFIX can be used within ~// to
print a symbol with a package prefix.
+ The debugger and backtracing are more robust against buggy
PRINT-OBJECT methods.
* Optimization:
+ calls to static functions on x86-64 use less instructions.
+ compute encode-universal-time at compile time when possible.
+ when referencing internal functions as #'x, don't go through
an indirect fdefn structure.
+ SLEEP doesn't cons on non-immediate floats and on ratios.
+ (mod fixnum) type-checks are performed using one unsigned
comparison, instead of two.
+ enable more modular arithmetic transforms in the presence of
conditionals.
+ bitwise OR forms can now trigger modular arithmetic as well,
when the result is known to be negative.
+ recognize more cases of useless LOGAND/LOGIOR with constants.
+ comparisons between rationals and constant floats or between
integers and constant ratios are now converted to rationals/integers
at compile time.
+ Smaller and faster DOUBLE-FLOAT-LOW-BITS on x86-64.
* Bug Fix:
+ problems with NCONC type derivation (reported by Jerry James).
+ EXPT type derivation no longer constructs bogus floating-point
types. (reported by Vsevolod Dyomkin)
+ sb-bsd-sockets has correct declaration of the canonname field of
addrinfo. (lp#1187041, patch by Jerry James)
+ uninitialized type-error conditions can now be printed.
(lp#1184586)
+ tests for sb-bsd-sockets no longer use a predefined port for
listening, allowing several tests to run in parallel.
+ during disassembly to *COMPILER-TRACE-OUTPUT* instruction
prefixes as used on x86 and x86-64 no longer sometimes print incorrectly.
(lp#1085729)
+ Specialised SIMD-PACK types can be negated.
+ Modular arithmetic is more robust. (incidentally fixes another bug
reported by Eric Marsden)
+ FP return values from foreign calls are always rounded to single
or double float precision on x87.
+ Known-safe vector access on x86oids should not fail spuriously
when the index is of the form (+ x constant-positive-integer).
+ backtrace printer no longer tries to create very large lists when
the arg-count register is clobberred by other code. (lp#1192929)
+ x86 should never signal an FP exception while boxing an FP value,
a situation that lands us into ldb.
-------------------------------------------------------------------
Wed Jun 5 07:07:56 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.8
* Notice:
+ The implementation of MAP-ALLOCATED-OBJECTS (the heart of
ROOM, plus a few SB-INTROSPECT functions) has been completely
rewritten; it may now exhibit different bugs than before.
* New feature:
+ minimal runtime/compiler intrastructure support
for SSE SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64
via the build-time
+ sb-simd-pack. This should enable intrinsics extensions
as libraries, without patching SBCL itself.
* Enhancement:
+ RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
+ boxed vectors (vectors of T or of FIXNUM) can now
be stack-allocated on PPC.
+ "fixed objects" can now be stack-allocated on PPC.
+ WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
+ (sb-introspect:find-definition-sources-by-name x :vop) now
also returns VOPs which do not translate any functions, and
finds defoptimizer types ir2convert and stack-allocate-result.
+ better type derivation for APPEND, NCONC, LIST. (lp#538957)
+ MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the heap
in a manner similar to the GC rather than its previous ad-hoc
scheme, and is therefore no less and possibly more accurate.
+ fixes and enhancements related to Unicode:
- the character database information has been updated to
Unicode 6.2;
- support for canonical and compatibility decomposition of
characters has been added, along with support for primary
composition;
- support for Unicode normalization forms of strings (NFC,
NFKC, NFD and NFKD) has been included;
- querying the character database for code points not defined
by Unicode gives less wrong answers (lp#1178038, reported by
Ken Harris)
+ print intermediate evaluation results for some ASSERTed
expressions. (lp#789497) (patch by Alexandra Barchunova)
+ x86-64 disassemblies are annotated with unboxed constant
values when there are references to (RIP-relative) unboxed
constants.
* Bug fix:
+ type derivation for LOG{AND,IOR,XOR} scales linearly instead
of quadratically with the size of the input in the worst case.
(lp#1096444)
+ handle errors when initializing *default-pathname-defaults*,
sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like
character decoding errors, or directories being deleted.
+ Loading a core with a discontiguous dynamic space now correctly
computes the amount of dynamic space used.
+ disassembler missing ",8" on SHLD
+ backtracing through INTERNAL-ERROR signal handlers on systems
that provide an "invalid" stack frame link for the signal handler
itself now use the saved-fp-and-pc mechanism to pick up from
the stack frame in the interrupt (signal) context. This is
known to affect threaded FreeBSD/x86-64.
+ some LOOP statements couldn't be compiled. (lp#1178989)
+ sb-sequence:dosequence works on literal vectors.
+ errors in generic arithmetic show the assembly routine's caller
on x86 and x86-64. (lp#800343)
+ Compile-time type errors should never result in COMPILE-FILE
failure. (lp#943953)
+ Known bad local calls do not cause strange failures when emitting
or dumping code. (lp#504121)
+ Multiply-inlined structure constructor don't cause IR2-time
codegen errors: type checks are inserted as necessary.
(lp#1177703)
+ Unsigned modular arithmetic is correctly converted into signed
modular arithemtic (mostly to exploit fixnum-width VOPs).
(lp#1026634)
+ a combination of inlined local function with &optional and
recursion no longer causes undescriptive compiler errors.
(lp#1180992)
+ sub-word BOOLEAN alien types now disregard higher order bits
when testing for non-zero-ness.
+ (CONCATENATE 'null ...) no longer fails for generic sequences.
(lp#1162301)
+ Type mismatch for the value of conditional expressions are
correctly reported when detected at compile-time, instead of
complaining about a constant NIL (similar for non-EQ-comparable
catch tags).
+ Referring to INLINE global functions as values should not result
in a compilation failure. (lp#1035721)
* Optimization:
+ faster ISQRT on fixnums and small bignums
+ faster and smaller INTEGER-LENGTH on fixnums on x86-64.
+ On x86-64, the number of multi-byte NOP instructions used
for code alignment is now always minimal.
+ On 64-bit targets, the compiler generates much faster code
for type checks for types known at compile time that are
smaller than (SIGNED-BYTE 64) or (UNSIGNED-BYTE 64) and larger
than FIXNUM, and their COMPLEX variants.
+ On x86 targets, more uses of ALIEN-FUNCALL during cross
compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance.
+ ROOM no longer conses so egregiously on non-x86oid systems.
+ associative bitwise operations reassociate patterns like
(f (f x k1) k2) to expose (f x (f k1 k2)). Same for + and * of
rational values.
+ quasiquote expressions now perform more constant folding,
instead of consing equal lists at runtime. (lp#1026439)
+ local call analysis of inlined higher-order function should
converge more quickly, resulting in better code for complex
functions.
+ On x86-64, medium (word-sized but wider than 32 bits) integer
constants are handled more cleverly, especially when they can
be represented as sign-extended (signed-byte 32). (Based on a
patch by Douglas Katzman)
+ IF/IF conversion should reliably result in sane code when
(some of) the results of the inner IF are always false or
always true.
+ On x86oids, variable right shifts of machine words are
compiled into straight SAR/SHR, instead of going through the
generic VOP. (lp#1066204)

- Update to version 1.1.7
* Enhacements:
+ TRACE :PRINT-ALL handles multiple-valued forms. (#457053)
* Bug Fix:
+ allocation slot option works for condition slots (#1049404)
redefining conditions does not lead to multiple evaluations of
hairy slot initfunctions anymore (#1164969)
+ CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
(#1164970)
+ function constants now work as initforms and default initarg values
of conditions (#539517)
svref/(setf svref) on symbol macros don't crash the compiler
anymore. (Minimal test case provided by James M. Lawrence on
sbcl-devel)
+ no more bogus ## references when pretty printing backquoted forms
with non-trivial structure sharing. (#1161218)
+ Don't signal an error on (setf (documentation nil 'function) "doc").
Signal a style-warning instead when trying to set documentation
of NIL for all other documentation types.)
+ modular arithmetic involving large constants and conditionals
should no longer result in spurious dead code elimination.
+ our mach exception handler can seemingly called very early in
the program execution process on OS X 10.8.0. Try and handle
that case robustly, without potentially leaking mach ports
too much.
* Optimization:
+ LOGBITP and LOGTEST optimizations from x86 portedto x86_64.

Thu Apr 4 10:28:49 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.6
* Enhancements:
+ the continuable error when defknown-ing over extant fndb
entries can be ignored by passing :overwrite-fndb-silently
t as a keyword argument to sb-c:defknown (after attributes).
Useful to allow defknown to be re-loaded. Use with
:allow-other-keys t for backward compatibility.
* Optimization:
+ compiler is much faster in compiling SVREF and
(SETF SVREF) forms.
* Bug fix:
+ Prevent a make-array transform from modifying source
forms causing problems for inlined code. Thanks to Bart Botta.
(regression since 1.0.42.11-bis)
+ clear-output calls the correct gray stream routine,
sb-gray:stream-clear-output. (lp#1153257)
+ an error is signalled for an invalid format modifier:
~<~@>. (lp#1153148)
+ Better error messages for package operations
(lp#1154776)
+ delete-package on a nonexistent package should signal
a cerror. (regression since 1.0.37.44).
+ bug fix: accessing &MORE (stack allocated &REST) arguments
checks bounds. (lp#1154946, lp#1072112)
+ bug fix: compiling make-array no longer signals an error when
the element-type is an uknown type, a warning is issued instead.
Thanks to James Kalenius (lp#1156095)
+ SEARCH on generic (non-VECTOR non-LIST) sequence types
no longer produces wrong results for some inputs.
(Thanks to Jan Moringen.) (lp#1153312)

Wed Feb 27 09:24:08 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.5
* minor incompatible change: SB-SPROF:WITH-PROFILING no longer
loops by default.
* New Features:
+ package local nicknames. See manual for details.
+ SB-EXT:MAP-DIRECTORY provides a powerful interface
for directory traversal: it is the backend used by SBCL for
CL:DIRECTORY.
* Enhancements:
+ easier to use restarts for resolving name-conflicts resulting
from IMPORT, EXPORT, or USE-PACKAGE.
+ variant DEFPACKAGE forms now signal a full error with restarts
provided for resolving the situation. (lp#891351)
+ by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant
DEFPACKAGE forms can now signal a full error with restarts
provided for resolving the situation. (lp#891351)
+ make-random-state now uses CryptGenRandom as a seed on Windows.
(Thanks to Anton Kovalenko.) (lp#1102748)
+ backtrace improvements
** secondary CLOS dispatch functions have better debug names
(lp#503081)
** easier to read method names in backtraces. See
SB-DEBUG:*METHOD-FRAME-STYLE*.
** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are
available as forwards-compatible replacements for
SB-DEBUG:BACKTRACE and SB-DEBUG:BACKTRACE-AS-LIST.
** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as
the same information is available in less intrusive form as
frame annotations.
+ SB-POSIX now provides MAP-ANON.
+ test-suite results are colorized, failures in red,
unexpected success in green. Works on Windows and on terminals with
ANSI escape code support. Can be disabled with --no-color.
* Optimizations:
+ SB-CONCURRENCY:QUEUE implementation is more efficient.
(thanks to James M. Lawrence)
* Bug Fixes:
+ no more unused variable style warnings from RESTART-CASE
macroexpansion (lp#1113859)
+ no more unused variable style warnings when loading
sb-bsd-sockets.asd (lp#1114681)
+ deleting a package removes it from implementation-package lists of
other packages.
+ SB-SPROF:WITH-PROFILING is now usable in the Slime REPL on Darwin.
This does not fix the occasional "interrupt already pending"
issue, though.
+ (setf (documentation 'x 'function)) and (setf (documentation #'x t))
set documentation in different places. (regression since 1.0.43.63)
+ build on newer glibc. (lp#1095036)
- Removed sbcl-glibc217.patch as it is fixed upstream
-------------------------------------------------------------------
Fri Feb 1 16:37:13 UTC 2013 - toganm@opensuse.org
- Update to 1.1.4 version
* Optimization
+ LOOP expressions using "of-type character" have
slightly more efficient expansions.
* Bug Fixes :
+ very long (or infinite) constant lists in DOLIST do
not result in very long compile times or heap exhaustion
anymore. (lp#1095488)
+ `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918)
+ adjust-array ignored :initial-element for simple-vectors.
(lp#1096359)
+ optimizations to MAKE-INSTANCE with literal list
initargs no longer cause infinite loops (on circular data) or
violate eqlity constraints. (lp#1099708)
+ FIRST was not being open coded. (regression from 1.1.0)
- renamed and sbcl-0.9.5-personality.patch to
sbcl-1.1.4-personality.patch and reworked it.
-------------------------------------------------------------------
Tue Jan 8 14:25:42 UTC 2013 - toganm@opensuse.org
- Update to version 1.1.3
* Enhancements:
+ warnings about bad locale settings, LANG, LC_CTYPE,
etc. (#727625)
+ support for C-c to interrupt the foreground thread on
Windows. (Thanks to Anton Kovalenko.)
+ STDCALL alien callbacks. (Thanks to Anton Kovalenko.)
+ Safepoint builds on POSIX platforms can now optionally be
built without pseudo-atomic sequences and their run-time
overhead.
+ Threads created outside of Lisp can enter Lisp through alien
callbacks and appear as Lisp threads for the duration of that
function invocation. On safepoint builds only.
+ Miscellaneous improvements to namestrings and underlying
calls to OS functions for file system access on
Windows. (Thanks to Anton Kovalenko.)
+ The MSI installer support for Windows now uses Windows
Installer XML at least version 3.5 and includes various
usability improvements. (Thanks to Dmitry Kalyanov and Anton
Kovalenko.)
+ The sb-bsd-sockets contrib now supports non-blocking-mode on
Windows. (Thanks to Anton Kovalenko.)
+ The Windows backend now supports the x86-64 platform. (Thanks
to Anton Kovalenko.)
* Bug fixes:
+ fasls are now once again directly executable (on platforms
supporting shebang lines, with a suitably-installed sbcl).
+ make.sh --help no longer runs clean.sh. (#937001)
+ Fix CAS access to slots of direct instances of structure
classes in the presence of subclasses sharing the same
conc-name.
+ Logical pathname namestrings on Windows have been changed to
be lower-case, to minimize differences between POSIX and
Windows.
-------------------------------------------------------------------
Wed Dec 5 08:31:49 UTC 2012 - toganm@opensuse.org
- Update to 1.1.2 version
* Enhancements:
+ frlocks have been added to SB-CONCURRENCY contrib
module.
+ New feature sb-dynamic-core allows the runtime to
be rebuilt or relocated without requiring changes to the core
file on all linkage table platforms. Required on Windows.
(Thanks to Anton Kovalenko.)
+ Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.)
+ Support for the experimental safepoint-based stop-the-world
protocol on the PowerPC platform.
* Windows related bug fixes:
- Use sbcl in buildrequires instead of clisp since the package is
now available in Factory as well
* Added sbclrc.sample and README.openSUSE which explains the usage
of the sample init file usage with sbcl
* Patched install.sh to install the above
(sbcl-1.1.2-install.patch)
* use the customize-target-features.lisp to enable/disable
features
* disable test-frfrlock sb-concurrency by allowing it to fail on
linux see https://bugs.launchpad.net/sbcl/+bug/1087955
(sbcl-disable-frlock-test.patch)
-------------------------------------------------------------------

-------------------------------------------------------------------
Sat Nov 3 12:33:49 UTC 2012 - toganm@opensuse.org
- Update to 1.1.1 version
* Enhancements and optimizations:
+ WITH-COMPILATION-UNIT no longer grabs the world-lock.
(COMPILE and COMPILE-FILE still do.)
+ The SPARC backend now supports the precise generational
(GENCGC) garbage collection. Enabled by default on
Solaris/SPARC and Linux/SPARC. Thanks to Raymond Toy (via
CMUCL).
+ add experimental support for the SB-THREAD feature and the
timer facility on Windows. Thanks to Dmitry Kalyanov and Anton
Kovalenko. Threads are enabled by default, and this version of
SBCL is considered to be the last and final release to
officially support building with threads disabled.
+ The compiler no longer rotates loops in some cases where this
transformation actually lead to worse code being generated.
* Bug Fixes:
+ SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
symbol-macros by lexical bindings.
+ stack allocation was prevented by high DEBUG declaration in
several cases.
+ SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
(thanks to SANO Masatoshi)
+ PARSE-NATIVE-NAMESTRING performed non-native parsing when
:JUNK-ALLOWED was true.
+ type derivation inferred overly conservative types for unions
of array types. (#1050768)

-------------------------------------------------------------------
Tue Oct 2 14:57:01 UTC 2012 - toganm@opensuse.org
- Update to 1.1.0
* Enhancements:
+ New variable, sb-ext:*disassemble-annotate* for controlling source
annotation of DISASSEMBLE output. Defaults to T.
+ TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
WAIT-P argument added to WITH-RECURSIVE-LOCK.
+ SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations on
list heads.
+ Optional features (not enabled by default) allow the use of signals
for inter-thread synchronization to be reduced on certain supported
platforms (currently Linux, Solaris, and FreeBSD on x86 and x86-64).
Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer) to test
these experimental features. Known remaining bugs include minor
thread safety issues, less timely freeing of memory by GC, and certain
(not yet optimally low) runtime overhead. Thanks to Anton Kovalenko.
* optimization:
+ CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
comparisons, particularly on almost-sorted inputs.
* Bug fixes
+ Reading floats with large exponents no longer takes too much time
before reporting that the exponent is too large.
+ SB-BSD-SOCKETS:SOCKET-RECEIVE with a UDP socket now works correctly
when the received datagram is larger than the provided buffer.
(#1023438, thanks to Robert Uhl)
+ SB-EXT:GET-CAS-EXPANSION returned a bogus read-form when given a
SYMBOL-VALUE form with a constant symbol argument.
+ SB-EXT:GET-CAS-EXPANSION signaled an error when a macro expanding
into a DEFCAS defined place was used as the place.
+ FIND and POSITION signaled a type-error when non-bits where looked
for from bit-vectors.
+ a race condition around thread creation could (in SBCL 1.0.57) lead
to internal errors or crashes (#1058799).
* documentation:
+ a section on random number generation has been added to the
manual. (#656839)
- rebased sbcl-1.0.54-optflags.patch
-------------------------------------------------------------------
Tue Aug 7 10:38:52 UTC 2012 - toganm@opensuse.org
- Update to 1.0.58
* enhancement: implicit generic function warnings now specify the
package in which the new generic function is being created.
* enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform
non-destructive updates of CAS-able places (similar to
Clojure's swap!).
* enhancement: run-program no longer decodes and re-encodes
environment when :environment argument is not
provided. (#985904)
* enhancement: errors during compiler-macro expansion no longer
cause runtime errors, only a compile-time warning, otherwise
behaving as if the compiler macro had declined to expand.
* optimization: On x86-64, code alignment of block headers is done
with multi-byte NOPs now instead of repetitions of the
single-byte NOP.
* optimization: MAP-INTO is substantially faster when the target
sequence is of unknown type; mapping into lists is no longer
O(N^2). (thanks to James M. Lawrence)
* optimization: the compiler no longer heap-conses to check exits
in cases where the exit function is dynamic extent, or when it
can prove the exit function cannot escape.
* optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of
unknown element type, and vectors that aren't SIMPLE-ARRAYs.
* optimization: CL:SORT and CL:STABLE-SORT are more efficient in
execution speed (around 1/3 the time in some cases), and a
little better in terms of comparison calls. (Thanks to Takeru
Ohta)
* bug fix: On SPARC, a limitation on the number of code constants
emittable by the compiler has been lifted, allowing certain
long functions to compiled and assembled which had previously
been unsupported; fixes cl-bench on this ISA (#1008996).
* bug fix: potential for infinite recursion during compilation of
CLOS slot typechecks when dependency graph had
loops. (#1001799)
* bug fix: error forms reported with some program-errors were not
escaped properly.
* bug fix: functions from EVAL are now on more equal footing with
functions from COMPILE. (#1000783, #851170, #922408)
* bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method
combination objects as its :METHOD-COMBINATION argument, not
just lists designating method combinations. (#936513)
* bug fix: run-program no longer unconditionally uses /tmp/ for
temporary files. (#968837).
* bug fix: restore build on solaris/sparc. (#1008506) bug fix: an
* issue with LDB in the PowerPC backend has been resolved; this
* fixes an issue found with cl-postgres (thanks to Tomas
* Hlavaty).
* bug fix: compiler-macro lambda-lists specifying non-keyword
symbols as keyword arguments no longer accidentally match
unevaluated symbols against them.
* bug fix: FORMAT used to loop infinitely in some cases when a
COLINC parameter was zero, now it signals an error. (#905817,
fixed since 1.0.56.19)
* bug fix: run-program with :pty t no longer makes the pty as the
process's controling terminal.
-------------------------------------------------------------------
Tue May 22 08:38:41 UTC 2012 - toganm@opensuse.org
- Update to 1.0.57 changes in sbcl-1.0.57 relative to sbcl-1.0.56:
* RANDOM enhancements and bug fixes:
** bug fix: the range and distribution of random integers could be
catastrophically wrong when the compiler derived the type of its
argument as a disjoint set of small integers.
** bug fix: the distribution of random integers is now completely
uniform even when the specified limit is not a power of two.
(Previously some values could be about 0.1 % more probable than
others in the worst case.)
** RANDOM on large integer arguments is generally faster and conses
less than before; this is visible for fixnums above a length of
about 24 bits, but extremely so for bignums: the old implementation
used time and space quadratical in the size of the argument there,
the new one is linear.
* enhancement: redesigned protocol for quitting SBCL. SB-EXT:EXIT is the new
main entry point, SB-EXT:QUIT is deprecated.
* enhancement: additions to the SB-THREAD API: RETURN-FROM-THREAD,
ABORT-THREAD, MAIN-THREAD-P, and MAIN-THREAD.
* enhancement: FASL loading no longer grabs the world-lock.
* enhancement: GENCGC reclaims space more aggressively when objects being
allocated are a large fraction of the total available heap space.
(lp#936304)
* enhancement: backtraces show the correct number of arguments for frames
called with too many arguments.
* enhancement: support for abort(3), exit(3), and _exit(2) has been added to
SB-POSIX.
* enhancement: ASDF has been updated 2.21.
* optimization: fewer uses of full calls to signed modular functions.
(lp#903821)
* optimization: typechecking alien values is typically 5 x faster.
* optimization: FDEFINITION, SYMBOL-FUNCTION, MACRO-FUNCTION, and FBOUNDP
are 20% faster.
* bug fix: file compilation performance issues when dumping subtypes
of CHARACTER (lp#994487)
* bug fix: fixed disassembly of some SSE instructions on x86-64.
* bug fix: SB-SIMPLE-STREAMS signals an error for bogus :CLASS arguments in
OPEN. (lp#969352, thanks to Kambiz Darabi)
* bug fix: CASE normal-clauses do not allow T and OTHERWISE as keys.
(lp#959687)
* bug fix: (SETF (FIND-CLASS X) NIL) removed proper name of the underlying
classoid even if X was not the proper name of the class. (lp#941102)
* bug fix: declaration leakage between lexical environments due to careless
use of NCONC in MAKE-LEXENV. (lp#924276)
* bug fix: ENSURE-DIRECTORIES-EXIST now works when
*default-pathname-defaults* contains NAME or TYPE components.
* bug fix: PPRINT couldn't print improper lists with CARs being some symbols
from CL package, e.g. (loop . 10).
* bug fix: run-program with existent or non-existent files for :output or
:input when :if-output-exists or :if-input-does-not-exist are NIL properly
returns NIL instead of signalling an obscure error.
* bug fix: fix miscompilation of some logand forms with large constant
arguments. (lp#974406)
* bug fix: account for funcallable-instance objects properly in ROOM.
* bug fix: incorrect octets reported for c-string decoding errors.
(lp#985505)
* bug fix: miscompilation of LDB on the PowerPC platform. (thanks to Bruce
O'Neel)
* bug fix: better input error reporting for COMPILE-FILE. (lp#493380)
* bug fix: default size of non-nursery generations has been shrunk on GENCGC,
allowing faster release of memory back to the OS. (lp#991293)
* bug fix: WITH-DEADLINE (:SECONDS NIL :OVERRIDE T) now drops any
existing deadline for the dynamic scope of its body.
* bug fix: compiler-internal interval arithmetic needed to be more
conservative about open intervals when operated on by monotonic but not
strictly-monotonic functions. (lp#975528)
* bug fix: copy-tree caused stack exhaustion on long linear lists, and now
it's also slightly faster. (lp#998926)
* bug fix: better error messages for malformed declarations.
(lp#1000239)
* bug fix: define-condition didn't return the name of the defined condition.
* documentation:
** improved docstrings: REPLACE (lp#965592)
-------------------------------------------------------------------
Thu May 3 09:48:28 UTC 2012 - toganm@opensuse.org

SBCL can now be built using Clang.
ASDF has been updated 2.20.
* bug fix: compiler errors when weakening hairy integer types.
(#913232)

for inlining when the function has never been requested for
inlining. (#963530)
