* [codeview] Refactor symbol records to use same pattern as types.Zachary Turner2016-05-231-274/+325
| | | | | | | | | | | This will pave the way to introduce a full fledged symbol visitor similar to how we have a type visitor, thus allowing the same dumping code to be used in llvm-readobj and llvm-pdbdump. Differential Revision: http://reviews.llvm.org/D20384 Reviewed By: rnk llvm-svn: 270475

| | | | | | | | | | | | | | * Reworks the CVSymbolTypes.def to work similarly to TypeRecords.def. * Moves some enums from SymbolRecords.h to CodeView.h to maintain consistency with how we do type records. * Generalize a few simple things like the record prefix * Define the leaf enum and the kind enum similar to how we do with tyep records.

* [codeview] Add type stream merging prototypeReid Kleckner2016-05-141-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This code is intended to be used as part of LLD's PDB writing. Until that exists, this is exposed via llvm-readobj for testing purposes. Type stream merging uses the following algorithm: - Begin with a new empty stream, and a new empty hash table that maps from type record contents to new type index. - For each new type stream, maintain a map from source type index to destination type index. - For each record, copy it and rewrite its type indices to be valid in the destination type stream. - If the new type record is not already present in the destination stream hash table, append it to the destination type stream, assign it the next type index, and update the two hash tables. - If the type record already exists in the destination stream, discard it and update the type index map to forward the source type index to the existing destination type index.

| | | | | | | | | | | | | | | | | | Summary: Port the dumper in llvm-readobj over to it. I'm planning to use this visitor to power type stream merging. While we're at it, try to switch from StringRef to ArrayRef<uint8_t> in some places.

* Move CodeViewTypeStream to DebugInfo/CodeViewZachary Turner2016-05-031-137/+14
| | | | | | | | | | | | | Ability to parse codeview type streams is also needed by DebugInfoPDB for parsing PDBs, so moving this into a library gives us this option. Since DebugInfoPDB had already hand rolled some code to do this, that code is now convereted over to using this common abstraction.

* NFC: An iterator for stepping through CodeView type stream in llvm-readobjAdrian McCarthy2016-05-021-39/+125
| | | | | | | | | | | | This is a small refactoring step toward moving CodeView type stream logic from llvm-readobj to a library. It abstracts the logic of stepping through the stream into an iterator class and updates llvm-readobj to use that iterator. This has no functional change; llvm-readobj produces identical output. The next step is to abstract the parsing of the different leaf types and then move that and the iterator into a library. Since this is my first contrib outside LLDB, please let me know if I'm messing up on any of the LLVM style guidelines, idioms, or patterns.

* Thread Expected<...> up from libObject’s getName() for symbols to allow ↵Kevin Enderby2016-04-201-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | llvm-objdump to produce a good error message. Produce another specific error message for a malformed Mach-O file when a symbol’s string index is past the end of the string table. The existing test case in test/Object/macho-invalid.test for macho-invalid-symbol-name-past-eof now reports the error with the message indicating that a symbol at a specific index has a bad sting index and that bad string index value. Again converting interfaces to Expected<> from ErrorOr<> does involve touching a number of places. Where the existing code reported the error with a string message or an error code it was converted to do the same. There is some code for this that could be factored into a routine but I would like to leave that for the code owners post-commit to do as they want for handling an llvm::Error. An example of how this could be done is shown in the diff in lib/ExecutionEngine/RuntimeDyld/RuntimeDyldImpl.h which had a Check() routine already for std::error_code so I added one like it for llvm::Error . Also there some were bugs in the existing code that did not deal with the old ErrorOr<> return values.  So now with Expected<> since they must be checked and the error handled, I added a TODO and a comment: “// TODO: Actually report errors helpfully” and a call something like consumeError(NameOrErr.takeError()) so the buggy code will not crash since needed to deal with the Error. Note there fixes needed to lld that goes along with this that I will commit right after this. So expect lld not to built after this commit and before the next one. llvm-svn: 266919

* [CodeView] Use assembler directives for line tablesReid Kleckner2016-01-281-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new family of .cv_* directives to LLVM's variant of GAS syntax: - .cv_file: Similar to DWARF .file directives - .cv_loc: Similar to the DWARF .loc directive, but starts with a function id. CodeView line tables are emitted by function instead of by compilation unit, so we needed an extra field to communicate this. Rather than overloading the .loc direction further, we decided it was better to have our own directive. - .cv_stringtable: Emits the codeview string table at the current position. Currently this just contains the filenames as null-terminated strings. - .cv_filechecksums: Emits the file checksum table for all files used with .cv_file so far. There is currently no support for emitting actual checksums, just filenames. This moves the line table emission code down into the assembler. This is in preparation for implementing the inlined call site line table format. The inline line table format encoding algorithm requires knowing the absolute code offsets, so it must run after the assembler has laid out the code. David Majnemer collaborated on this patch. llvm-svn: 259117

* [CodeView] Add support for dumping binary annotationsDavid Majnemer2016-01-141-1/+100
| | | | | | | | | | | | Binary annotations are encoded along the lines of UTF-8 and ECI but with a few minor differences. The algorithm specified in "ECMA-335 CLI Section II.3.2 - Blobs and Signatures" is used to compress binary annotations. Signed binary annotations are encoded like unsigned annotations except the sign bit is rotated left to reduce the number of bits needed to be encoded. llvm-svn: 257742
