--- Comment #3 from Uroš Bizjak <ubizjak at gmail dot com> ---
Confirmed.
sse.md includes a named pattern defined with non-conforming operands:
(define_expand "float<floatunssuffix>v2div2sf2"
[(set (match_operand:V4SF 0 "register_operand" "=v")
(vec_concat:V4SF
(any_float:V2SF (match_operand:V2DI 1 "nonimmediate_operand" "vm"))
(match_dup 2)))]
"TARGET_AVX512DQ && TARGET_AVX512VL"
"operands[2] = CONST0_RTX (V2SFmode);")
V2SF vectorization now triggers this expander.
