--- Comment #1 from Uroš Bizjak <ubizjak at gmail dot com> ---
The relevant pattern is present in sse.md:
(define_insn "fix_truncv4dfv4si2<mask_name>"
[(set (match_operand:V4SI 0 "register_operand" "=v")
(fix:V4SI (match_operand:V4DF 1 "nonimmediate_operand" "vm")))]
"TARGET_AVX || (TARGET_AVX512VL && TARGET_AVX512F)"
"vcvttpd2dq{y}\t{%1, %0<mask_operand2>|%0<mask_operand2>, %1}"
but for some reason not exercised by target-independent part of the compiler.
Confirmed as a tree optimization problem.
