The same problem happens on x86_64:
--cut here--
void foo (void);
float test (float a, float b)
{
foo ();
return b;
}
--cut here--
gcc -O2
test:
.LFB0:
subq $24, %rsp
movss %xmm1, (%rsp)
call foo
A movss (%rsp), %xmm1
addq $24, %rsp
B movaps %xmm1, %xmm0
ret
We could move from stack directly to xmm0
