cpuset is 1024 rather than 256 since FreeBSD version 1400090
The sanitizer libraries in llvm-devel fail to build on CURRENT because of the
recent change to the size of cpuset. See LLVM bug
https://github.com/llvm/llvm-project/issues/63485
The build error looks like
/wrkdirs/usr/ports/devel/llvm-devel/work-default/llvm-project-9d1bcb70ec8830ad85c0756a03022d3811537284/compiler-rt/lib/sanitizer_common/sanitizer_platform_limits_freebsd.cpp:569:1:
error: static assertion failed due to requirement
'sizeof(__sanitizer::__sanitizer_cpuset) >= sizeof(_cpuset)':
COMPILER_CHECK(sizeof(__sanitizer_cpuset_t) >= sizeof(cpuset_t));
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I attached a fix to make it build. I have not tested the sanitizer libraries
built with this patch.
In the context of the llvm sanitizer libraries it does not seem to be possible
to include the correct header files to get the cpuset size definition. The
sanitizer libraries wrap library calls and the wrappers definitions conflict.
