* [PDB] Merge Global and Publics Builders.Zachary Turner2017-08-091-222/+0
| | | | | | | | | | | | | | | | | | | | | The publics stream and globals stream are very similar. They both contain a list of hash buckets that refer into a single shared stream, the symbol record stream. Because of the need for each builder to manage both an independent hash stream as well as a single shared record stream, making the two builders be independent entities is not the right design. This patch merges them into a single class, of which only a single instance is needed to create all 3 streams. PublicsStreamBuilder and GlobalsStreamBuilder are now merged into the single GSIStreamBuilder class, which writes all 3 streams at once. Note that this patch does not contain any functionality change. So we're still not yet writing any records to the globals stream. All we're doing is making it so that when we do start writing records to the globals, this refactor won't have to be part of that patch.

* [PDB] Initialize the std::array<ulittle32_t> used for the gsi bitmapReid Kleckner2017-07-271-0/+2
| | | | | | | | With ASan, we would write about 512 bytes of malloc fill value to the PDB, with some random bits ORed in here and there. Dumping the PDB would always fail reliably. llvm-svn: 309331
* [PDB] Write public symbol records and the publics hash tableReid Kleckner2017-07-271-27/+160
| | | | | | | | | | | | | | Summary: MSVC link.exe records all external symbol names in the publics stream. It provides similar functionality to an ELF .symtab. Reviewers: zturner, ruiu Subscribers: hiraditya, llvm-commits Differential Revision: https://reviews.llvm.org/D35871 llvm-svn: 309303

* [PDB] Improve GSI hash table dumping for publics and globalsReid Kleckner2017-07-261-1/+1
| | | | | | | | | | | | | | | The PDB "symbol stream" actually contains symbol records for the publics and the globals stream. The globals and publics streams are essentially hash tables that point into a single stream of records. In order to match cvdump's behavior, we need to only dump symbol records referenced from the hash table. This patch implements that, and then implements global stream dumping, since it's just a subset of public stream dumping. Now we shouldn't see S_PROCREF or S_GDATA32 records when dumping publics, and instead we should see those record in the globals stream. llvm-svn: 309066
* [lld/pdb] Create an empty public symbol record stream.Zachary Turner2017-07-101-0/+89
This is part of the continuing effort to increase parity between LLD and MSVC PDBs. link still doesn't like our PDBs, so the most obvious thing to check was whether adding an empty publics stream would get it to do something else. It still fails in the same way but at least this removes one more variable from the equation. The next logical step would be to try creating an empty globals stream.
