From 8a6bb1d08686ae921601d00bdbcc76c96e5b92de Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 1 Feb 2018 20:57:22 +0000 Subject: Remove some math_private.h libc_fe* overrides. math_private.h headers for configurations lacking support for floating-point exceptions and rounding modes define various libc_fe* macros to override the default versions with ones that discard any exception or rounding mode arguments. Three of the four macros defined in these headers are no longer needed there: those macros are only used in fma implementations that are not used for such configurations, now all those configurations properly use soft-fp fma implementations instead. (Effectively, those macros were a workaround to allow glibc to build in the absence of a proper fma implementation for this case - now there is such an implementation, there is no need to support building the wrong implementation for those configurations.) Thus, this patch removes the unnecessary macros. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/m68k/coldfire/nofpu/math_private.h (libc_fesetround): Remove macro.
