[PATCH] D79792: [AMDGPU] New SIInsertHardClauses pass

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

Actually depending on shouldCluster is a problem. First soft clauses are formed and then you turn them into hard clauses. Soft clauses impose higher register pressure but then you simply break them here, essentially wasting registers. It is either both passes should be guided by the same heuristic or none.
