--- Comment #1 from Oleg Endo <olegendo at gcc dot gnu.org> ---
The same applies to FP loads/stores, as this example shows:
float*
test_func_00 (float* p, float* x)
{
float r = 0;
r += *p++;
r += *p++;
*x = r;
return p;
}
fmov.s @r4+,fr2 ! 7 movsf_ie/6 [length = 4]
fldi0 fr1 ! 8 movsf_ie/3 [length = 2]
mov r4,r0 ! 26 movsi_ie/2 [length = 2]
fadd fr2,fr1 ! 9 addsf3_i [length = 2]
fmov.s @r0+,fr2 ! 10 movsf_ie/6 [length = 4]
fadd fr2,fr1 ! 11 addsf3_i [length = 2]
fmov.s fr1,@r5 ! 12 movsf_ie/7 [length = 4]
rts/n ! 35 *return_i [length = 4]
