--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I have a fix for aarch64, able to produce now:
```
f:
.LFB0:
.cfi_startproc
stp x0, x1, [sp, -32]!
.cfi_def_cfa_offset 32
.cfi_offset 0, -32
.cfi_offset 1, -24
stp x2, x3, [sp, 16]
.cfi_offset 2, -16
.cfi_offset 3, -8
ldr w0, [x0]
cmp w0, 5
bne .L8
add sp, sp, 32
.cfi_remember_state
.cfi_def_cfa_offset 0
ret
.L8:
.cfi_restore_state
mov x5, x1
ldp x2, x3, [sp, 16]
ldp x0, x1, [sp], 32
.cfi_restore 1
.cfi_restore 0
.cfi_restore 2
.cfi_restore 3
.cfi_def_cfa_offset 0
add sp, sp, x5
ret
.cfi_endproc
```
Which is exactly what we should produce I think.
The patch is a bit more complex than I expected but that is due to how aarch64
has some of the most complex epilogues.
