Lu <hjl.to...@gmail.com> Date: Wed Nov 17 11:41:12 2021 -0800 x86: Remove "%!" before ret Before MPX was removed, "%!" was mapped to case '!': if (ix86_bnd_prefixed_insn_p (current_output_insn)) fputs ("bnd ", file); return; After CET was added and MPX was removed, "%!" was mapped to case '!': if (ix86_notrack_prefixed_insn_p (current_output_insn)) fputs ("notrack ", file); return; ix86_notrack_prefixed_insn_p always returns false on ret since the notrack prefix is only for indirect branches. Remove the unused "%!" before ret. PR target/103307 * config/i386/i386.c (ix86_code_end): Remove "%!" before ret. (ix86_output_function_return): Likewise. * config/i386/i386.md (simple_return_pop_internal): Likewise.
