* Parse the TPI (type information) stream of PDB files.Zachary Turner2016-05-031-4/+11
| | | | | | | | | | | | | | | This parses the TPI stream (stream 2) from the PDB file. This stream contains some header information followed by a series of codeview records. There is some additional complexity here in that alongside this stream of codeview records is a serialized hash table in order to efficiently query the types. We parse the necessary bookkeeping information to allow us to reconstruct the hash table, but we do not actually construct it yet as there are still a few things that need to be understood first.

* Fix crash in PDB when loading corrupt file.Zachary Turner2016-04-291-0/+7
| | | | | | | | | | There are probably hundreds of crashers we can find by fuzzing more. For now we do the simplest possible validation of the block size. Later, more complicated validations can verify that other fields of the super block such as directory size, number of blocks, agree with the size of the file etc. llvm-svn: 268084

* [llvm-pdbdump] Try to appease the ASan botDavid Majnemer2016-04-291-0/+5
| | | | | | We didn't check that the file was large enough to hold a super block. llvm-svn: 267965
* [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
* Parse and dump PDB DBI Stream Header InformationZachary Turner2016-04-261-0/+18
| | | | | | | | | | | | | | | | | | 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.

* Resubmit "Refactor raw pdb dumper into library"Zachary Turner2016-04-251-0/+238
| | | | | | | This fixes a number of endianness issues as well as an ODR violation that hopefully causes everything to be happy. llvm-svn: 267431

| | | | | | r267049 broke multiple buildbots (e.g. clang-cmake-mips, and clang-x86_64-linux-selfhost-modules) which the follow-ups have not yet resolved and this is preventing subsequent committers from being notified about additional failures on the affected buildbots. llvm-svn: 267148

* Refactor raw pdb dumper into libraryZachary Turner2016-04-211-0/+249
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.
