As a newbie of PowerPC backend, I think what @jsji proposed will ease my mind burden when faced with `o` ended instructions. I have read ISA-3.0 and know

  A period (.) as the last character of an instruction
  mnemonic means that the instruction *records* sta-
  tus information in certain fields of the Condition
  Register as a side effect of execution.

I can directly react to the effect of record-form instruction if it ends with `_record`. If `_record` is too long, how about `_rec`, just like X86's `_alt` ended instructions?
