float_control pragma applies to clang #183

Closed walbourn closed 5 months ago

walbourn commented 5 months ago

The float_control pragma is supported by clang, so we should enable it there as well as for MSVC. This impacts IsInfinite tests functions and the SSE/SSE2 rounding implementation.

Note that currently the clang/LLVM compiler does not properly respect this pragma for SSE intrinsics code, so the recommendation would be to avoid using /fp:fast with clang/LLVM.
