- Fix LDXXFLAGS (thank you Stefan Krah for providing the patch)
-------------------------------------------------------------------
Wed May 7 12:09:23 UTC 2025 - Matej Cepl <mcepl@cepl.eu>
- Update to 4.0.1 (bsc#1242704):
- Add Cygwin support.
- Update config.guess and config.sub to the latest versions.
- Fix pkg-config files for custom paths.
- Set LD/LDXX unconditionally to CC/CXX, since LDFLAGS/LDXXFLAGS from ./configure rely on it.
- Update to 4.0.0:
- sync soversion and major_version
- The added number formatting feature requires an ABI change,
hence the increase to SOVERSION=4.
- Packagers outside of the Linux distributions sometimes use
the major version number as the equivalent of SOVERSION on
their platforms and have an incorrect SOVERSION for 2.5.1,
which requires SOVERSION=3.
- While SOVERSION is not required to match the major
version number (example: glibc), mpdecimal will from
now on take the path of least resistance and always use
SOVERSION=MPD_MAJOR_VERSION.
- The jump to 4.0.0 should also remind users that a C++ library
is available.
- Support for out-of-tree build.
- Support for pkg-config.
- Unix: support for Loongson.
- Unix: support for CheriBSD.
- Compilers: support for icx, icpx, ibm-clang_r, ibm-clang++_r,
CompCert, clang-cl and emscripten.
- Windows: support for MSYS2/MinGW.
- MSVC: the build now uses /O2 /DNDEBUG.
- MSVC: new arm64/arm32 cross build scripts.
- AIX: the shared libraries are now installed as versioned
objects, e.g., shr4.o, shr4_64.o.
- New ./configure switches:
- --enable-static: enable/disable the build of the static
libraries (default: enabled).
- --enable-pc: enable/disable the install of the pkgconfig
files (default: enabled).
- --enable-doc: enable/disable the install of the documentation
(default: enabled).
- New man pages direct users to the mpdecimal-doc package or
the online HTML documentation.
- The prebuilt HTML documentation is now in the separate
mpdecimal-doc package, which gives distributions that reject
prebuilt documentation the option to disregard it and use the
new man pages.
- libmpdec:
- Add the “z” format specifier (coerce negative zeros to
positive).
- In extremely rare cases the transcendental functions (exp,
ln, log10) did not set the Subnormal/Underflow flags. The
reason is that in the case of an exponent boundary the Ziv
correction loop for correct rounding requires very few
iterations to arrive at the correctly rounded result, but
may need many more iterations to arrive at the correct
flags.
- In these cases, Subnormal/Underflow is not very
informative, so the status quo was to skip the extra
iterations.
- Version 4.0.0 now specializes exponent boundary cases
and uses up to five additional iterations to set
Subnormal/Underflow. The refactored code has no speed
penalty on average; in fact, in the deccheck tests (random
tests with a bias towards corner cases) it is slightly
faster.
- No cases have been found where more than two additional
iterations are required, but they may exist.
-eability fixes
- mpd_qset_string_exact(), mpd_qset_i64_exact() and
mpd_qset_u64_exact() can now be called with a nonzero
status. Previously, the functions could return
NaN/Invalid_operation in that case.
- This is listed under “reliability fixes” since there is
no possible scenario under which these functions would
legitimately be called with a nonzero status.
- libmpdec++
- Add input validation for Decimal.shiftl(), Decimal.shiftr()
and Decimal::ln10().

- Switch on _multibuild with the separate test step (to minimize
dependencies).
- Add a basic baselibs.conf.
