--- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- Author: aldyh Date: Wed Sep 13 16:35:02 2017 New Revision: 252319 URL: https://gcc.gnu.org/viewcvs?rev=252319&root=gcc&view=rev Log: i386: Set priority to P_AES for Westmere The difference between Nehalem and Westmere is AES. We should set priority to P_AES for Westmere, not P_PROC_SSE4_2 which is for Nehalem. Otherwise, we will pick Nehalem implementation on Westmere. Tested on Westmere. PR target/81743 * config/i386/i386.c (get_builtin_code_for_version): Set priority to P_AES for Westmere. Modified: branches/range-gen2/gcc/ChangeLog branches/range-gen2/gcc/config/i386/i386.c
