[PATCH] D120265: AMDGPU: Use the implicit kernargs for code object version 5

[Changpeng Fang via Phabricator via llvm-commits]

cfang updated this revision to Diff 415256.
cfang added a comment.

1. Introduce a common function, SITargetLowering::loadImplicitKernelArgument, which is used

in both getSegmentAperture and lowerTrapHsaQueuePtr.

2. Define enum ImplicitKernargOffset to get implicit kernel argument offset directly.
  - This eliminates the functions to get the offset.
