From: Karl Meakin <[email protected]>
The bodies of `mov<ALLI>cc` and `mov<GPF>cc` are identical, so merge
them by using a new mode iterator that combines `ALLI` and `GPF`.
gcc/ChangeLog:
* config/aarch64/aarch64.md (mov<ALLI>cc): Merge with ...
(mov<ALLI>cc): ... this.
* config/aarch64/iterators.md(ALLI_GPF): New mode iterator.
