From 515f463f52b8e4f048e6818d0db2dd2ae45e5f36 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 19 Dec 2018 21:48:03 +0000 Subject: Remove x86 mathinline.h sinh, cosh, tanh inlines. Continuing the removal of bits/mathinline.h inlines that would better be done by the compiler, this patch removes x86 inlines for sinh, cosh and tanh functions (inlines only previously present for fast-math, non-SSE 32-bit x86). I've filed for adding such inlines as an optimization in GCC. I believe the only remaining part of the x86 bits/mathinline.h that does anything useful with current compilers after this patch is the __LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to remove the whole header and move that inline to a sysdeps math_private.h header in a subsequent patch. Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline definition. (cosh): Likewise.
