Hi Richard, Jakub,
Can you take a look at this patch? The last review from Kirill was in
June.
Thanks.

There are many duplicated AVX2/AVX512 vec_dup patterns like:
(define_insn "avx2_vec_dup"
[(set (match_operand:VF1_128_256 0 "register_operand" "=v")
(vec_duplicate:VF1_128_

Remove duplicated AVX2/AVX512 vec_dup patterns and replace them with
subreg. gcc.target/i386/avx2-vbroadcastss_ps256-1.c is changed by
avx2_test:
.cfi_startproc
- vmovaps x(%rip), %xmm1
- vbroadcastss%xmm1, %ymm0
+ vbroadcastssx(%rip), %ymm0
vmovaps %ymm
