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.

Subject: [PATCH, 8/10] aarch64: ccmp insn patterns
Hi,
The patch adds two insn patterns for ccmp instructions.
cbranchcc4 is introduced to generate optimized conditional branch without
an additional compare against the result of ccmp.
OK for trunk?
Thanks!
