We have llvm-readobj for dumping CodeView from object files, and llvm-pdbutil has always been more focused on PDB. However, llvm-pdbutil has a lot of useful options for summarizing debug information in aggregate and presenting high level statistical views. Furthermore, it's arguably better as a testing tool since we don't have to write tests to conform to a state-machine like structure where you match multiple lines in succession, each depending on a previous match. llvm-pdbutil dumps much more concisely, so it's possible to use single-line matches in many cases where as with readobj tests you have to use multi-line matches with an implicit state machine. Because of this, I'm adding object file support to llvm-pdbutil. In fact, this mirrors the cvdump tool from Microsoft, which also supports both object files and pdb files. In the future we could perhaps rename this tool llvm-cvutil. In the meantime, this allows us to deep dive into object files the same way we already can with PDB files. llvm-svn: 312358
