* [llvm-pdbdump] Restore error messages, handle bad block sizesDavid Majnemer2016-04-281-1/+1
| | | | | | | We lost the ability to report errors, bring it back. Also, correctly validate the block size. llvm-svn: 267955

* Read the rest of the DBI substreams, and parse source info.Zachary Turner2016-04-281-11/+124
| | | | | | | | | | | | | We now read out the rest of the substreams from the DBI streams. One of these substreams, the FileInfo substream, contains information about which source files contribute to each module (aka compiland). This patch additionally parses out the file information from that substream, and dumps it in llvm-pdbdump. Differential Revision: http://reviews.llvm.org/D19634 Reviewed by: ruiu llvm-svn: 267928
* Parse module information from DBI stream.Zachary Turner2016-04-273-2/+161
| | | | | | | | | | | | This gets more data out of the DBI strema of the PDB. In particular it extracts the metadata for the list of modules (compilands) that this PDB contains info about, and adds support for dumping these fields to llvm-pdbdump.

* [PDB] Fix function names for private symbols in PDBsReid Kleckner2016-04-271-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: llvm-symbolizer wants to get linkage names of functions for historical reasons. Linkage names are only recorded in the PDB for public symbols, and the linkage name is apparently stored separately in some "public symbol" record. We had a workaround in PDBContext which would look for such symbols when the user requested linkage names. However, when given an address that was truly in a private function and public funciton, we would accidentally find nearby public symbols and return those function names. The fix is to look for both function symbols and public symbols and only prefer the public symbol name if the addresses of the symbols agree.

* Parse and dump PDB DBI Stream Header InformationZachary Turner2016-04-265-1/+191
| | | | | | | | | | | | | | | | | | The DBI stream contains a lot of bookkeeping information for other streams. In particular it contains information about section contributions and linked modules. This patch is a first attempt at parsing some of the information out of the DBI stream. It currently only parses and dumps the headers of the DBI stream, so none of the module data or section contribution data is pulled out. This is just a proof of concept that we understand the basic properties of the DBI stream's metadata, and followup patches will try to extract more detailed information out.

* Refactor raw pdb dumper into libraryZachary Turner2016-04-215-3/+484
| | | | | | | | | | | | | | | | | | PDB parsing code was hand-rolled into llvm-pdbdump. This patch moves the parsing of this code into DebugInfoPDB and makes the dumper use this. This is achieved by implementing the skeleton of RawPdbSession, the non-DIA counterpart to the existing PDB read interface. None of the type / source file / etc information is accessible yet, so this implementation is not yet close to achieving parity with the DIA counterpart, but the RawSession class simply holds a reference to a PDBFile class which handles parsing the file format. Additionally a PDBStream class is introduced which allows accessing the bytes of a particular stream in a PDB file.

* [DebugInfoPDB] Raise getSymIndexId() up to PDBSymbolZachary Turner2016-02-171-0/+1
| | | | | | | | | | | | | Every symbol, no matter what it's tag is, supports the method getSymIndexId(). However, this was being forwarded on every concrete symbol type, so if someone had a PDBSymbol that they didn't know what type it was (or simply didn't have an instance of the concrete symbol type), they would not be able to get its index id. This patch moves the method up to PDBSymbol, so that no matter what type of object you have, you can always get its id. llvm-svn: 261153
* [DebugInfoPDB] Teach Variant to support string types.Zachary Turner2016-02-172-22/+36
| | | | | | | | | | The IDiaSymbol::getValue() method returns a variant. Until now, I had never encountered a string value, so the Variant wrapper did not support VT_BSTR. Now we have need to support string values, so this patch just adds support for one extra type to Variant. llvm-svn: 261152

* Improve DWARFDebugFrame::parse to also handle __eh_frame.Pete Cooper2015-12-181-1/+2
| | | | | | | | | | | | | | | LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's. This code improves DWARFDebugFrame::parse to do the same for parsing. This also allows llvm-objdump to support the --dwarf=frames option which objdump supports. This option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse. http://reviews.llvm.org/D15535 Reviewed by Rafael Espindola. llvm-svn: 256008
