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

--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
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.
