Removing dead frame indices for VGPR to AGPR spills is incorrect when the frame index is shared by multiple objects, which may occur due to stack slot coloring. The problem is that subsequent code that processes the other object will assert because the stack frame index is marked dead. Removing dead frame indices is needed prior to stack slot coloring, which is what happens with SGPR to VGPR spills. These spills are lowered prior to stack slot coloring, but the VGPR to AGPR spills are processed afterwards during the Prolog/Epilog Inserter pass. This patch marks the VGPR to AGPR spill slot as dead if the slot is not used by another object. Differential Revision: https://reviews.llvm.org/D115996 |
