--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For aarch64. this can be done on the rtl leve really:
```
(set (reg:SI 107 [ _6 ])
(mult:SI (if_then_else:SI (eq (reg:CC 66 cc)
(const_int 0 [0]))
(const_int 1 [0x1])
(const_int -1 [0xffffffffffffffff]))
(reg:SI 108 [ c_5 ])))
```
simplify that into:
```
(set (reg:SI 107 [ _6 ])
(if_then_else:SI (eq (reg:CC 66 cc)
(const_int 0 [0]))
(reg:SI 108 [ c_5 ])
(neg:SI (reg:SI 108 [ c_5 ]))))
```
Or match the first form for a define_insn_and_split and split it into the
second form.
This won't solve PR 122837 though.
PR111078 is needed for a different reason though.
