LLVM Virtual registers after RA pass?
...ameIndex’ function implementation.
However, whenever that code is executed, I get the assertion "MachineCopyPropagation should be run after register allocation!” at a later stage.
I have seen that at least a couple of backend implementations (including ARM Thumb) create virtual registers in ‘eliminatedFrameIndex’.
What am I missing?, is there something that I need to set for virtual registers to be allowed after the RA pass, and specifically in the ‘eliminateFrameIndex’ function?
Thanks,
