It's my fault. %m/%M work well in the new patch.
And I add a check
aarch64_ccmp_mode_to_code (GET_MODE (operands[1])) == GET_CODE (operands[5])
on the patterns to make sure that the compare and CC mode are aligned.
Looks good.

Ping?
Patch is attached for easy to apply.
Move the cstorecc4 pattern from [PATCH, 10/10] aarch64: Handle ccmp in
ifcvt to make it work with cmov to this patch, since cmov optimization does
not depend on that patch.
Thanks!
