Delete Branch "factory"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
- 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().
