The original patch was submitted 2 years ago, and required manual intervention due to the recent *.c to *.cc rename. Back story: When GCC is configured and built on non-glibc platforms, it seems very little to no effort is made to enumerate the available C99 libm functions. It is all or nothing for C99 libm. The patch introduces a new function, used on only FreeBSD, to inform gcc that it has C99 libm functions (minus a few which clearly GCC does not check nor test). The patch introduces no regression on x86_64-*-freebsd while allowing an additional 31 new passes. === gcc Summary === w/o patch w patch # of expected passes 175405 175434 # of unexpected failures 1081 1051 # of unexpected successes 20 20 # of expected failures 1459 1459 # of unresolved testcases 10 10 # of unsupported tests 3252 3252 === g++ Summary === w/o patch w patch # of expected passes 225338 225341 # of unexpected failures 678 676 # of expected failures 2071 2071 # of unresolved testcases 11 11 # of unsupported tests 10353 10353 === gfortran Summary === w/o patch w patch # of expected passes 65901 65901 # of unexpected failures 12 12 # of expected failures 272 272 # of unsupported tests 100 100 2022-04-15 Steven G.
