Add the beginning of PDB diffing support. For now this only diffs the stream directory and the MSF Superblock. Future patches will drill down into individual streams to find out where the differences lie. Differential Revision: https://reviews.llvm.org/D30908 llvm-svn: 297689

Rename some PDB classes. We have a lot of very similarly named classes related to dealing with module debug info. This patch has NFC, it just renames some classes to be more descriptive (albeit slightly more to type). The mapping from old to new class names is as follows: Old | New ModInfo | DbiModuleDescriptor ModuleSubstream | ModuleDebugFragment ModStream | ModuleDebugStream With the corresponding Builder classes renamed accordingly.

[PDB] Don't build the entire source file list up front. I tried to run llvm-pdbdump on a very large (~1.5GB) PDB to try and identify show-stopping performance problems. This patch addresses the first such problem. When loading the DBI stream, before anyone has even tried to access a single record, we build an in memory map of every source file for every module. In the particular PDB I was using, this was over 85 million files. Specifically, the complexity is O(m*n) where m is the number of modules and n is the average number of source files (including headers) per module. The whole reason for doing this was so that we could have constant time access to any module and any of its source file lists. However, we can still get O(1) access to the source file list for a given module with a simple O(m) precomputation, and access to the list of modules is already O(1) anyway. So this patches reduces the O(m*n) up-front precomputation to an O(m) one, where n is ~6,500 and n*m is about 85 million in my pathological test case.

[llvm-pdbutil] Add support for dumping detailed module stats. This adds support for dumping a summary of module symbols and CodeView debug chunks. This option prints a table for each module of all of the symbols that occurred in the module and the number of times it occurred and total byte size. Then at the end it prints the totals for the entire file. Additionally, this patch adds the -jmc (just my code) option, which suppresses modules which are from external libraries or linker imports, so that you can focus only on the object files and libraries that originate from your own source code. llvm-svn: 311338

[llvm-pdbutil] Add support for dumping detailed module stats. This adds support for dumping a summary of module symbols and CodeView debug chunks. This option prints a table for each module of all of the symbols that occurred in the module and the number of times it occurred and total byte size. Then at the end it prints the totals for the entire file. Additionally, this patch adds the -jmc (just my code) option, which suppresses modules which are from external libraries or linker imports, so that you can focus only on the object files and libraries that originate from your own source code. llvm-svn: 311338
