[TxMt] Assembly language patterns

I just joined this list and seem to be having trouble posting, but I'll give it another try.

I was wondering what the prevailing wisdom is regarding pattern naming conventions for assembly languages. I'm working on a bundle for an obscure chip (the long-discontinued Motorola DSP96002 which we still use in a variety instruments on account of it being one of the few DSPs which supports extended precision floats). So far, I've got patterns like "assembly.opcode", "assembly.directive", and "assembly.directive.macro", but I'm not sure this is the way to go. Should these all be under "keyword", for example?
