Lu <address@hidden>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=dd22218cf26fa5d8beade7266de391a28e63527b commit dd22218cf26fa5d8beade7266de391a28e63527b Author: H.J. Lu <address@hidden> Date: Sun Mar 17 07:25:08 2019 +0800 x86: Correctly optimize EVEX to 128-bit VEX/EVEX We can optimize 512-bit EVEX to 128-bit EVEX encoding for upper 16 vector registers only when AVX512VL is enabled. We can't optimize EVEX to 128-bit VEX encoding when AVX isn't enabled.
