From 9ed2e15ff4c9ff27c09103fa13a051e3605cbe5f Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 9 May 2018 19:45:47 +0000 Subject: Move math_opt_barrier, math_force_eval to separate math-barriers.h. This patch continues cleaning up math_private.h by moving the math_opt_barrier and math_force_eval macros to a separate header math-barriers.h. At present, those macros are inside a "#ifndef math_opt_barrier" in math_private.h to allow architectures to override them and then use a separate math-barriers.h header, no such #ifndef or #include_next is needed; architectures just have their own alternative version of math-barriers.h when providing their own optimized versions that avoid going through memory unnecessarily. The generic math-barriers.h has a comment added to document these two macros. In this patch, math_private.h is made to #include , so files using these macros do not need updating yet. That is because of uses of math_force_eval in math_check_force_underflow and math_check_force_underflow_nonneg, which are still defined in math_private.h. Once those are moved out to a separate header, that separate header can be made to include , as can the other files directly using these barrier macros, and then the include of from math_private.h can be removed. Tested for x86_64 and x86. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/math-barriers.h: New file. * sysdeps/generic/math_private.h [!math_opt_barrier] (math_opt_barrier): Move to math-barriers.h.
