* | [MachineSink] Fix for breaking phi edges with instructions with multiple defs | David Green | 2020-05-07 | 1 | -0/+56 |
BreakPHIEdge would be set based on whether the instruction needs to insert a new critical edge to allow sinking into a block where the uses are PHI nodes. But for instructions with multiple defs it would be reset on the second def, allowing the instruciton to sink where it should not. Fixes PR44981 Differential Revision: https://reviews.llvm.org/D78087 (cherry picked from commit 44c4ba34d001dcf538d7396007b5611d6f697f86) |
