Add feholdexcept inline in generic math_private.h

System Internals / glibc - Joseph Myers [codesourcery.com] - 1 February 2018 20:56 EST

Continuing the process of improving and cleaning up the handling of configurations lacking support for floating-point exceptions and rounding modes, this patch adds trivial inline definitions of feholdexcept and __feholdexcept to the set of inlines for such configurations in math_private.h. These inlines were missing from the tile version used as a basis for the previous inlines, despite a few such function calls ending up in libm.so.

Tested with build-many-glibcs.py. As expected, installed stripped shared libraries are unchanged for architectures supporting exceptions and rounding modes, but changed for architectures lacking such support.

- sysdeps/generic/math_private.h [!FE_HAVE_ROUNDING_MODES && FE_ALL_EXCEPT == 0] (feholdexcept): New inline function. [!FE_HAVE_ROUNDING_MODES && FE_ALL_EXCEPT == 0] (__feholdexcept): Likewise.
