Handle const0_operand for *avx2_pcmp<mode>3_1.
*<avx512>_eq<mode>3<mask_scalar_merge_name>_1 supports
nonimm_or_0_operand for op1 and op2, pass_combine would fail to lower
avx512 comparision back to avx2 one when op1/op2 is const0_rtx. It's
because the splitter only support nonimmediate_operand.
Failed to match this instruction:
(set (reg/i:V16QI 20 xmm0)
(vec_merge:V16QI (const_vector:V16QI [
(const_int -1 [0xffffffffffffffff]) repeated x16
])
(const_vector:V16QI [
(const_int 0 [0]) repeated x16
])
(unspec:HI [
(reg:V16QI 105 [ a ])
(const_vector:V16QI [
(const_int 0 [0]) repeated x16
])
(const_int 0 [0])
] UNSPEC_PCMP)))
The patch extend predicates of the splitter to handles that.
gcc/ChangeLog:
PR target/115517
* config/i386/sse.md (*avx2_pcmp<mode>3_1): Change predicate
of operands[1] and operands[2] from nonimmdiate_operand to
nonimm_or_0_operand.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr115517.c: New test.
