This target hook would be handy also for x86_64, which passes packed complex
SFmode values to and from function:
Following test:
_Complex float testf (_Complex float a, _Complex float b)
{
return a + b;
}
produces (-O2):
testf:
movq %xmm0, -8(%rsp)
movq %xmm1, -16(%rsp)
movss -4(%rsp), %xmm0
movss -8(%rsp), %xmm1
addss -12(%rsp), %xmm0
addss -16(%rsp), %xmm1
movss %xmm0, -20(%rsp)
movss %xmm1, -24(%rsp)
movq -24(%rsp), %xmm0
ret
Yes, indeed.
