- 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
