Commit Message

Liu, Hongtao July 11, 2023, 9:13 a.m. UTC 
Similar like we did for CMPXCHG, but extended to all
ix86_comparison_int_operator since CMPCCXADD set EFLAGS exactly same
as CMP.

When operand order in CMP insn is same as that in CMPCCXADD,
CMP insn can be eliminated directly.

When operand order is swapped in CMP insn, only optimize
cmpccxadd + cmpl + jcc/setcc to cmpccxadd + jcc/setcc when FLAGS_REG is dead
after jcc/setcc plus adjusting code for jcc/setcc.

gcc/ChangeLog:

	PR target/110591
	* config/i386/sync.md (cmpccxadd_<mode>): Adjust the pattern
	to explicitly set FLAGS_REG like *cmp<mode>_1, also add extra
	3 define_peephole2 after the pattern.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr110591.c: New test.
	* gcc.target/i386/pr110591-2.c: New test.
