--- Comment #3 from Alan Modra <amodra at gcc dot gnu.org> --- Author: amodra Date: Thu Jan 19 23:19:19 2017 New Revision: 244659 URL: https://gcc.gnu.org/viewcvs?rev=244659&root=gcc&view=rev Log: [RS6000] PR79144, cmpstrnsi optimization breaks glibc glibc compiled with current gcc-7 fails one test due to strcmp and strncmp appearing in the PLT. This is because the inline expansion of those functions falls back to a function call, but doesn't use the asm name for the call. PR target/79144 * config/rs6000/rs6000.c (expand_strn_compare): Get the asm name for strcmp and strncmp from corresponding builtin decl. Modified: trunk/gcc/ChangeLog trunk/gcc/config/rs6000/rs6000.c
