--- Comment #3 from Uroš Bizjak ---
This PR and PR95211 will be fixed by the for PR95125. Here, the offending
pattern should be renamed to something like
avx512dq_fix_truncv2sfv2di2
and an expander should be added:
(define_expand "fix_truncv2sfv2di2"
[(set (match_operand:V2DI 0 "register_operand")
(any_fix:V2DI
(match_operand:V2SF 1 "nonimmediate_operand")))]
"TARGET_AVX512DQ && TARGET_AVX512VL"
{
if (!MEM_P (operands[1]))
{
operands[1] = simplify_gen_subreg (V4SFmode, operands[1], V2SFmode, 0);
emit_insn (gen_avx512dq_fix_truncv2sfv2di2 (operands[0],
operands[1]));
DONE;
}
})

--- Comment #2 from Uroš Bizjak ---
The patch exposes another case of named pattern with non-conformant operand
mode.
This time, it is:
(define_insn "fix_truncv2sfv2di2"
[(set (match_operand:V2DI 0 "register_operand" "=v")
(any_fix:V2DI
(vec_select:V2SF
(match_operand:V4SF 1 "nonimmediate_operand" "vm")
(parallel [(const_int 0) (const_int 1)]]
"TARGET_AVX512DQ && TARGET_AVX512VL"
"vcvttps2qq\t{%1, %0|%0, %q1}"
[(set_attr "type" "ssecvt")
(set_attr "prefix" "evex")
(set_attr "mode" "TI")])
