Major user-facing changes: Many headers in llvm/DebugInfo/CodeView no longer include llvm/Support/BinaryStreamReader.h or llvm/Support/BinaryStreamWriter.h, those headers may need to be included manually. Several headers in llvm/DebugInfo/CodeView no longer include llvm/DebugInfo/CodeView/EnumTables.h or llvm/DebugInfo/CodeView/CodeView.h, those headers may need to be included manually.

to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
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

This was originally reverted because of some non-deterministic failures on certain buildbots. Luckily ASAN eventually caught this as a stack-use-after-scope, so the fix is included in this patch. llvm-svn: 305393
This is causing failures on linux bots with an invalid stream read. It doesn't repro in any configuration on Windows, so reverting until I have a chance to investigate on Linux. llvm-svn: 305371
This allows us to use yaml2obj and obj2yaml to round-trip CodeView symbol and type information without having to manually specify the bytes of the section. This makes for much easier to maintain tests. See the tests under lld/COFF in this patch for example. Before they just said SectionData: <blob> whereas now we can use meaningful record descriptions. Note that it still supports the SectionData yaml field, which could be useful for initializing a section to invalid bytes for testing, for example.
