--- Comment #1 from Hongtao.liu <crazylht at gmail dot com> ---
It looks like a regression since GCC9
typedef float v1sf __attribute__((vector_size(4)));
v1sf
foo43 (v1sf a, v1sf b, v1sf c)
{
return a * b + c;
}
gcc9 also don't generate vfmaddXXXss.
pushq %rbp
movq %rdi, %rax
movq %rsp, %rbp
andq $-32, %rsp
vmovss 24(%rbp), %xmm0
vmulss 16(%rbp), %xmm0, %xmm0
vaddss 32(%rbp), %xmm0, %xmm0
vmovss %xmm0, -64(%rsp)
movl -64(%rsp), %edx
movl %edx, (%rdi)
leave
ret
