So for the above before this change we had:
```
(insn:TI 597 596 598 2 (set (reg:DI 11 x11)
(reg/f:DI 31 sp)) "stack-check-prologue-16.c":16:1 65 {*movdi_aarch64}
(nil))
(insn 598 597 599 2 (set (mem:BLK (scratch) [0 A8])
(unspec:BLK [
(reg:DI 11 x11)
(reg/f:DI 31 sp)
] UNSPEC_PRLG_STK)) "stack-check-prologue-16.c":16:1 1169
{stack_tie}
(expr_list:REG_DEAD (reg:DI 11 x11)
(nil)))
```
After we get:
```
(insn 598 596 599 2 (set (mem:BLK (scratch) [0 A8])
(unspec:BLK [
(reg:DI 31 sp [11]) repeated x2
] UNSPEC_PRLG_STK)) "stack-check-prologue-16.c":16:1 1169
{stack_tie}
(nil))
```
Which seems to be ok, except we still have:
.cfi_def_cfa_register 11
That is because on:
(insn/f 596 595 598 2 (set (reg:DI 12 x12)
(plus:DI (reg:DI 12 x12)
(const_int 272 [0x110]))) "stack-check-prologue-16.c":16:1
153 {*adddi3_aarch64}
(expr_list:REG_CFA_DEF_CFA (reg:DI 11 x11)
(nil)))
We record x11 but never update it though that came before the mov for
x11 ... So it seems like cprop_hardreg had no idea it needed to update
it.
I suspect the other testcases are just propagation of sp into the
stores and such and just needed update. But the above testcase seems
getting broken cfi though I don't know how to fix it.
Thanks,
