* [CodeView] Support remaining debug subsection typesZachary Turner2017-06-091-1/+21
| | | | | | | | | | | | | | | | This adds support for Symbols, StringTable, and FrameData subsection types. Even though these subsections rarely if ever appear in a PDB file (they are usually in object files), there's no theoretical reason why they *couldn't* appear in a PDB. The real issue though is that in order to add support for dumping and writing them (which will be useful for object files), we need a way to test them. And since there is no support for reading and writing them to / from object files yet, making PDB support them is the best way to both add support for the underlying format and add support for tests at the same time. Later, when we go to add support for reading / writing them from object files, we'll need only minimal changes in the underlying read/write code. llvm-svn: 305037
* [llvm-pdbdump] Support native ordering of subsections in raw mode.Zachary Turner2017-06-081-6/+39
| | | | | | | | | | | | | This is the same change for the YAML Output style applied to the raw output style. Previously we would queue up all subsections until every one had been read, and then output them in a pre- determined order. This was because some subsections need to be read first in order to properly dump later subsections. This patch allows them to be dumped in the order they appear.

* [CodeView] Handle Cross Module Imports and Exports.Zachary Turner2017-06-051-0/+14
| | | | | | | | | | | | | | | While it's not entirely clear why a compiler or linker might put this information into an object or PDB file, one has been spotted in the wild which was causing llvm-pdbdump to crash. This patch adds support for reading-writing these sections. Since I don't know how to get one of the native tools to generate this kind of debug info, the only test here is one in which we feed YAML into the tool to produce a PDB and then spit out YAML from the resulting PDB and make sure that it matches. llvm-svn: 304738
* [CodeView] Rename ModuleDebugFragment -> DebugSubsection.Zachary Turner2017-05-301-0/+52
This is more concise, and matches the terminology used in other parts of the codebase more closely. llvm-svn: 304218
