[PATCH] D150388: [CodeGen]Allow targets to use target specific COPY instructions for live range splitting

[Yashwant Singh via Phabricator via llvm-commits]

yassingh added a comment.

As described in the [discourse thread], the target's implementation of isCopyInstrImpl() does not allow straightforward use of TII::isCopyInstr() in the regalloc pipeline. One MIPS test crashes(LLVM.CodeGen/Mips::dsp-r1.ll) on which I agree with @arsenm  can be a bug, and some tests in X86 and Thumb2 needed updating, which is to be expected?
