GlobalAliases may reference function definitions, but not function declarations. bugpoint would sometimes create invalid IR by deleting a function's body (thus mutating a function definition into a declaration) without first 'fixing' any GlobalAliases that reference that function definition. This change iteratively prevents that issue. Before deleting a function's body, it scans the module for GlobalAliases which reference that function. When found, it eliminates them using replaceAllUsesWith. Fixes PR20788. Patch by Nick Johnson! llvm-svn: 254171 |
