* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Add requires-b2 check to top-level build file.
* Bump B2 require to 5.2
* Update copyright dates.
* Move inter-lib dependencies to a project variable and into the build targets.
* Update build deps.
Looks like gcc 5 that is installed in MinGW on AppVeyor CI is not compiled
with C99 standard library enabled, which results in C++11 std::to_string
functions not being available. These functions are required by
Boost.Multiprecision.
Since legacy MinGW is quite outdated and increasingly poorly supported
across Boost libraries, remove it from CI rather than adding yet another
special case for disabling Boost.Multiprecision tests.
- Added gcc-12 and clang-14 through 15 jobs.
- Added C++23 testing for gcc and clang on Linux.
- Updated clang version for UBSAN job.
- Updated Ubuntu version for clang jobs to avoid having to use external APT
repository.
- Updated python package installation for compatibility with Ubuntu 22.04.
This allows to use compiler intrinsics and specialized hardware
instructions to compute log2, which results in better performance.
Also, added tests for the generic implementation using Boost.Multiprecision
integers.
Closes https://github.com/boostorg/integer/issues/31.
Removed unnecessary template specializations, removed workaround for
compilers not supporting partial template specializations. Use unsigned
integers for bit counting, which allows to replace the division with
a shift.
In Ubuntu 20.04 there appeared an updated version of the
software-properties-common package in focal-updates, which ships a newer
apt-add-repository version that doesn't support -P/-S/-U command line arguments.
Since we cannot rely on package version checks to determine apt-add-repository
capabilities, we have to parse its --help output instead.
Also, made source list processing more protected against spaces.
Make Multiprecision tests depend on <type_traits> and BOOST_NO_CXX11_HDR_TYPE_TRAITS.
Use specific Boost.Random headers and not <boost/random.hpp> as the latter pulls in some of Boost.Math which has now moved to C++11.
As of 2021, Boost.Multiprecision does not support C++03 and fails tests
of Boost.Integer. To mitigate, we replicate the preprocessor checks of
Boost.Multiprecision to disable its use in Boost.Integer tests in C++03
mode.
