| * | [codeview,pdb] Try really hard to conserve memory when reading. | Zachary Turner | 2016-05-27 | 1 | -7/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | PDBs can be extremely large. We're already mapping the entire PDB into the process's address space, but to make matters worse the blocks of the PDB are not arranged contiguously. So, when we have something like an array or a string embedded into the stream, we have to make a copy. Since it's convenient to use traditional data structures to iterate and manipulate these records, we need the memory to be contiguous. As a result of this, we were using roughly twice as much memory as the file size of the PDB, because every stream was copied out and re-stitched together contiguously. This patch addresses this by improving the MappedBlockStream to allocate from a BumpPtrAllocator only when a read requires a discontiguous read. Furthermore, it introduces some data structures backed by a stream which can iterate over both fixed and variable length records of a PDB. Since everything is backed by a stream and not a buffer, we can read almost everything from the PDB with zero copies.

| * | [codeview] Move StreamInterface and StreamReader to libcodeview. | Zachary Turner | 2016-05-25 | 1 | -2/+2 |
| | | | | | | | | | | | We have need to reuse this functionality, including making additional generic stream types that are smarter about how and when they copy memory versus referencing the original memory. So all of these structures belong in the common library rather than being pdb specific. llvm-svn: 270751 | ||||
| * | [llvm-pdbdump] Dump stream summary list. | Zachary Turner | 2016-05-25 | 1 | -0/+5 |
| | | | | | | | | | | Try to figure out what each stream is, and dump its name. This gives us a better picture of what streams we still don't understand. llvm-svn: 270653 | ||||
