--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The same issue happens on aarch64 with -mstrict-align though it is not as bad
as mips but the underlying issue is the same:
```
sub sp, sp, #32
.cfi_def_cfa_offset 32
str x0, [sp, 8]
lsr x0, x0, 32
bfi w0, w1, 28, 4
str w0, [sp, 12]
ldr x0, [sp, 8]
add sp, sp, 32
ret
```
Confirmed. there might be other bug reports which are very similar too.
