* Resubmit r301986 and r301987 "Add codeview::StringTable"Zachary Turner2017-05-031-4/+5
| | | | | | | | | | | | | | | | | | | | | | This was reverted due to a "missing" file, but in reality what happened was that I renamed a file, and then due to a merge conflict both the old file and the new file got added to the repository. This led to an unused cpp file being in the repo and not referenced by any CMakeLists.txt but #including a .h file that wasn't in the repo. In an even more unfortunate coincidence, CMake didn't report the unused cpp file because it was in a subdirectory of the folder with the CMakeLists.txt, and not in the same directory as any CMakeLists.txt. The presence of the unused file was then breaking certain tools that determine file lists by globbing rather than by what's specified in CMakeLists.txt In any case, the fix is to just remove the unused file from the patch set. llvm-svn: 302042
* Revert r301986 (and subsequent r301987).Daniel Jasper2017-05-031-5/+4
| | | | | | | | | The patch is failing to add StringTableStreamBuilder.h, but that isn't even discovered because the corresponding StringTableStreamBuilder.cpp isn't added to any CMakeLists.txt file and thus never built. I think this patch is just incomplete. llvm-svn: 302002
* Make codeview::StringTable.Zachary Turner2017-05-021-4/+5
| | | | | | | | | | | | | | | | | | | | Previously we had knowledge of how to serialize and deserialize a string table inside of DebugInfo/PDB, but the string table that it serializes contains a piece that is actually considered CodeView and can appear outside of a PDB. We already have logic in llvm-readobj and MCCodeView to read and write this format, so it doesn't make sense to duplicate the logic in DebugInfoPDB as well. This patch makes codeview::StringTable (for writing) and codeview::StringTableRef (for reading), updates DebugInfoPDB to use these classes for its own writing, and updates llvm-readobj to additionally use StringTableRef for reading. It's a bit more difficult to get MCCodeView to use this for writing, but it's a logical next step. llvm-svn: 301986
* Rename pdb::StringTable -> pdb::PDBStringTable.Zachary Turner2017-05-021-6/+6
| | | | | | | | With the forthcoming codeview::StringTable which a pdb::StringTable would hold an instance of as one member, this ambiguity becomes confusing. Rename to PDBStringTable to avoid this. llvm-svn: 301948
* [Support] Move Stream library from MSF -> Support.Zachary Turner2017-03-021-3/+3
| | | | | | | | | | After several smaller patches to get most of the core improvements finished up, this patch is a straight move and header fixup of the source. Differential Revision: https://reviews.llvm.org/D30266 llvm-svn: 296810
* [PDB] Add BinaryStreamError.Zachary Turner2017-02-281-5/+4
| | | | | | | This migrates the stream code away from MSFError to using its own custom Error class. llvm-svn: 296494
* [PDB] Make streams carry their own endianness.Zachary Turner2017-02-281-1/+1
| | | | | | | | | | | | | Before the endianness was specified on each call to read or write of the StreamReader / StreamWriter, but in practice it's extremely rare for streams to have data encoded in multiple different endiannesses, so we should optimize for the 99% use case. This makes the code cleaner and more general, but otherwise has NFC. llvm-svn: 296415
* [PDB] Partial resubmit of r296215, which improved PDB Stream Library.Zachary Turner2017-02-271-6/+6
| | | | | | | | | | | | | | | | | This was reverted because it was breaking some builds, and because of incorrect error code usage. Since the CL was large and contained many different things, I'm resubmitting it in pieces. This portion is NFC, and consists of: 1) Renaming classes to follow a consistent naming convention. 2) Fixing the const-ness of the interface methods. 3) Adding detailed doxygen comments. 4) Fixing a few instances of passing `const BinaryStream& X`. These are now passed as `BinaryStreamRef X`. llvm-svn: 296394
* Revert r296215, "[PDB] General improvements to Stream library." and followings.NAKAMURA Takumi2017-02-251-10/+7
| | | | | | | | | | | | | | | | | r296215, "[PDB] General improvements to Stream library." r296217, "Disable BinaryStreamTest.StreamReaderObject temporarily." r296220, "Re-enable BinaryStreamTest.StreamReaderObject." r296244, "[PDB] Disable some tests that are breaking bots." r296249, "Add static_cast to silence -Wc++11-narrowing." std::errc::no_buffer_space should be used for OS-oriented errors for socket transmission. (Seek discussions around llvm/xray.) I could substitute s/no_buffer_space/others/g, but I revert whole them ATM. Could we define and use LLVM errors there? llvm-svn: 296258
* [PDB] General improvements to Stream library.Zachary Turner2017-02-251-7/+10
| | | | | | | | | | | | | | | This adds various new functionality and cleanup surrounding the use of the Stream library. Major changes include: * Renaming of all classes for more consistency / meaningfulness * Addition of some new methods for reading multiple values at once. * Full suite of unit tests for reader / writer functionality. * Full set of doxygen comments for all classes. * Streams now store their own endianness. * Fixed some bugs in a few of the classes that were discovered by the unit tests. llvm-svn: 296215
* [PDB] Rename Stream related source files.Zachary Turner2017-02-251-3/+3
| | | | | | | | | | | | | | This is part of a larger effort to get the Stream code moved up to Support. I don't want to do it in one large patch, in part because the changes are so big that it will treat everything as file deletions and add, losing history in the process. Aside from that though, it's just a good idea in general to make small changes. So this change only changes the names of the Stream related source files, and applies necessary source fix ups. llvm-svn: 296211
* Don't assume little endian in StreamReader / StreamWriter.Zachary Turner2017-02-181-1/+1
| | | | | | | In an effort to generalize this so it can be used by more than just PDB code, we shouldn't assume little endian. llvm-svn: 295525
* [pdb] Add the ability to resolve TypeServer PDBs.Zachary Turner2017-02-161-2/+9
| | | | | | | | | | | | | | Some PDBs or object files can contain references to other PDBs where the real type information lives. When this happens, all type indices in the original PDB are meaningless because their records are not there. With this patch we add the ability to pull type info from those secondary PDBs.

* NFC: Rename (PDB) RawSession to NativeSessionAdrian McCarthy2017-01-251-0/+404
This eliminates one overload on the term Raw. Differential Revision: https://reviews.llvm.org/D29098 llvm-svn: 293104
