libgfortran: Provide some further math library fallbacks [PR94694]
The following patch provides some further math library fallbacks. fmaf can be implemented using fma if available, fma and fmal can use x * y + z as fallback, it is not perfect, but e.g. glibc on various arches has been using that as fallback for many years, and copysign/copysignl/fabs/fabsl can be implemented using corresponding __builtin_* if we make sure that gcc expands it inline instead of using a library call (these days it is expanded inline on most targets). 2020-04-22 Jakub Jelinek <jakub@redhat.com> PR libfortran/94694 PR libfortran/94586 * configure.ac: Add math func checks for fmaf, fma and fmal. Add HAVE_INLINE_BUILTIN_COPYSIGN check. * c99_protos.h (copysign, fmaf, fma, fmal): Provide fallback prototypes. (HAVE_COPYSIGN, HAVE_FMAF, HAVE_FMA, HAVE_FMAL): Define if not defined and fallback version is provided. * intrinsics/c99_functions.c (copysign, fmaf, fma, fmal): Provide fallback implementations if possible * configure: Regenerated. * config.h.in: Regenerated. * math.m4 (GCC_CHECK_MATH_INLINE_BUILTIN_FALLBACK1, GCC_CHECK_MATH_INLINE_BUILTIN_FALLBACK2): New.
