- 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().

Thu Sep 2 13:07:52 UTC 2021 - Matej Cepl <mcepl@suse.com>
|
|
|
|
- Switch on _multibuild with the separate test step (to minimize
|
|
dependencies).
|
|
- Add a basic baselibs.conf.
