Hello, I am developing GlobalISel for MIPS. I have a few questions and observations about defining legality of generic instruction and also possible combining of instructions and artifacts in pre/post legalizer combiner or elsewhere (e.g. in some sort of instruction-select patterns). I look at legality as "If generic instruction can be selected into machine instruction, it is legal".
