--- Comment #3 from Andrew Pinski  ---
The arm code generation was fixed in GCC 5 for the testcase in comment #0.
The x86_64 code generation was fixed in GCC 9 for the testcase in comment #2.

So fixed a long time ago for both.

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)
callfoo
A   movss   (%rsp), %xmm1
addq$24, %rsp
B   movaps  %xmm1, %xmm0
ret

We could move from stack directly to xmm0
