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.
