Given that I'm only somewhat up-to-speed on the DAG ISel scheme and not much at all on the Global ISel scheme, I'm tempted to work on the former and then the latter. So I'll look at the CodeGenDAGPatterns messages first. Then I will take a look at Global ISel. Matt: Can you suggest one or two things about Global ISel that could use some work? I won't get to it quickly, but it will

I would like to know why this patch https://reviews.llvm.org/D90973 had such a drastic size effect on the global isel tablegened matcher table for riscv. It only changed the DAG ISel table by about 15K. But the global isel table shrinks by over 200K. ~Craig On Wed, Nov 18, 2020 at 1:37 PM Paul C.
