[WIP][RISCV][GlobalISel] Select ALU GPR instructions
Needs ReviewPublic

Authored by lewis-revill on Mar 19 2020, 12:22 PM.



Some instruction selection patterns required for ALU GPR instructions have already been automatically imported from existing TableGen descriptions - this patch simply adds testing for them. Logic for selecting constants and copies has been added.

Missing copy tests for all permutations of virtual and physical registers

This can't early return, it still needs to constrain a virtual source
