The master branch has been updated by H.J. Lu <hjl@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=1848e567343e9c50979453463f34e0a55ba892eb commit 1848e567343e9c50979453463f34e0a55ba892eb Author: H.J. Lu <hjl.tools@gmail.com> Date: Fri May 27 10:05:39 2016 -0700 Update x86 CPU_XXX_FLAGS handling Support defining CPU_XXX_FLAGS with other CPU_XXX_FLAGS. Update CPU_XXX_FLAGS to enable more bits like x87 and SYSCALL. Don't enable MMX when enabling SSE, AVX or AVX512. Don't disable AVX nor AVX512 when disabling SSE. Don't disable AVX512 when disabling AVX. Disable F16C, FMA, FMA4 and XOP when disabling AVX. Add 87, no287, no387, no687, nosse2, nosse3, nossse3, nosse4.1, nosse4.2, nosse4 and noavx2 directives to x86 assembler.
