[PATCH] D88485: [SDag][AMDGPU] Maintain DAG divergence through instruction selection

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

That is beneficial to know if an instruction is divergent or uniform even after selection because it cannot be determined purely on a VALU vs SALU basis or register classes. However, I do not like that list of opcodes in the isSDNodeSourceOfDivergence(), it is error prone.
