[PATCH] D20297: AMDGPU/SI: Make kernarg.segment.ptr point to implicit arguments for non HSA

[Matt Arsenault via llvm-commits]

arsenm added a comment.

We could do what we are planning for OpenCL and add a struct pointer for future expansion at the end of some decided N bytes to reserve.

If 256 bytes were reserved at the beginning, that would be more than enough for any implicit needs and would keep the user arg base alignment the same (not sure that really matters).
