Needs comment explaining these. If you're writing custom operand handling maybe we shouldn't rename these? It is a weird case

I thought so too, but this matches the current src_modifiers field and uses an existing bit mask 4 bit value (OpselHI, OpselLo, Abs and Neg) in TableGen. There is also already a logic in place for asm printing using this bit mask. Also, in previous revision, it was a 2-bit field, which was reading the lower 2 bits hence not generating the right encoding for opsel bits. Though this MFMA instruction doesn't use neg and abs, I thought it would be cleaner to match the existing implementation.

I think it does support neg, it's just not wired up

Oh I see it, I see this in doc " NEG[1:0] and ABS[1:0] must be zero. NEG[2] and ABS[2] may be used to control matrix C" . So I will wire up a src2_modifier with neg/abs bits mapped and add some tests for it as well
