[PATCH] D74688: AMDGPU/GlobalISel: Support llvm.trap and llvm.debugtrap intrinsics

[Mahesha S via Phabricator via llvm-commits]

hsmhsm updated this revision to Diff 247447.
hsmhsm added a comment.

Couple of additional required changes

[1] SGPR01 is a new register created within legalizeTrapIntrinsic(), and we  actually need to get its type as LLT::scalar(64).
[2] Call to insertLiveInCopy() within getLiveInRegister() is only required if the copy is required from physical to virtual register.
[3] When call to insertLiveInCopy() within getLiveInRegister() is required, make sure that it is called irrespective of whether the virtual register is newly created within getLiveInRegister() or not.
