I hit a crash in the bitcode reader on some corrupt input where an MDString had somehow been attached to an instruction instead of an MDNode. This input is pretty bogus, but we shouldn't be crashing on bad input here. This change adds error handling in all of the places where we currently have unchecked casts from Metadata to MDNode, which means we'll error out instead of crashing for that sort of input. Unfortunately, I don't have tests. Hitting this requires flipping bits in the input bitcode, and committing corrupt binary files to catch these cases is a bit too opaque and unmaintainable. llvm-svn: 263742 |
