[PATCH] D107650: GlobalISel[RFC]: Avoid use of G_INSERT and G_EXTRACT in Legalizer

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

My general feeling is new opcodes should not be necessary, and that you're just trying to hide deficiencies in how we happen to lower some types now. I believe it is possible to fix legalization for every type with the existing set of opcodes (excluding cases that require an intermediate type that exceeds the range of LLT)
