[PATCH] D134423: [AMDGPU] Fix vgpr2sgpr copy analysis to check scalar operands of buffer instructions use scalar registers.

[krishna chaitanya sankisa via Phabricator via llvm-commits]

skc7 updated this revision to Diff 481592.
skc7 added a comment.

Made changes to only identify copy and its result used by soffset of MUBUF/MTBUF. needToBeConvertedToVALU returns false if such pattern is found. 
This also fixes vgpr-descriptor-waterfall-loop-idom-update.ll test, where the previous revision of the patch doesn't generate waterfall loop.
