--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:f7854b908977adce4ff669c4e0332ef868568b7c commit r12-5771-gf7854b908977adce4ff669c4e0332ef868568b7c Author: H.J. Lu <hjl.to...@gmail.com> Date: Sat Jun 19 08:16:45 2021 -0700 Add TARGET_IFUNC_REF_LOCAL_OK 1. On some targets, like PowerPC, reference to ifunc function resolver must be non-local so that compiler will properly emit PLT call. Add TARGET_IFUNC_REF_LOCAL_OK to allow binding indirect function resolver locally for targets which don't require special PLT call sequence. 2. Add ix86_call_use_plt_p to call local ifunc function resolvers via PLT. gcc/ PR target/51469 PR target/83782 * target.def (ifunc_ref_local_ok): Add a target hook. * varasm.c (default_binds_local_p_3): Force indirect function resolver non-local only if targetm.ifunc_ref_local_ok returns false. * config/i386/i386-expand.c (ix86_expand_call): Call ix86_call_use_plt_p to check if PLT should be used. * config/i386/i386-protos.h (ix86_call_use_plt_p): New. * config/i386/i386.c (output_pic_addr_const): Call ix86_call_use_plt_p to check if "@PLT" is needed.
