Denis Bakhvalov 99cf34b1da [MergedLoadStoreMotion] Sink stores to BB with more than 2 predecessors ... If we have: bb5: br i1 %arg3, label %bb6, label %bb7 bb6: %tmp = getelementptr inbounds i32, i32* %arg1, i64 2 store i32 3, i32* %tmp, align 4 br label %bb9 bb7: %tmp8 = getelementptr inbounds i32, i32* %arg1, i64 2 store i32 3, i32* %tmp8, align 4 br label %bb9 bb9: ; preds = %bb4, %bb6, %bb7 ... We can't sink stores directly into bb9. This patch creates new BB that is successor of %bb6 and %bb7 and sinks stores into that block. SplitFooterBB is the parameter to the pass that controls that behavior.
