* [PDB] Validate superblock addressesDavid Majnemer2016-12-181-0/+9
| | | | | | | - Validate the address of the block map. - Validate the address of the free block map. llvm-svn: 290053
* [pdb] handle missing pdb streams more gracefullyBob Haarman2016-12-051-0/+2
| | | | | | | | | | | | Summary: The code we use to read PDBs assumed that streams we ask it to read exist, and would read memory outside a vector and crash if this wasn't the case. This would, for example, cause llvm-pdbdump to crash on PDBs generated by lld. This patch handles such cases more gracefully: the PDB reading code in LLVM now reports errors when asked to get a stream that is not present, and llvm-pdbdump will report missing streams and continue processing streams that are present.

* Add CodeViewRecordIO for reading and writing.Zachary Turner2016-11-021-0/+20
| | | | | | | | | | | | | | | Using a pattern similar to that of YamlIO, this allows us to have a single codepath for translating codeview records to and from serialized byte streams. The current patch only hooks this up to the reading of CodeView type records. A subsequent patch will hook it up for writing of CodeView type records, and then a third patch will hook up the reading and writing of CodeView symbols.

* [CodeView] Refactor serialization to use StreamInterface.Zachary Turner2016-10-201-0/+63
| | | | | | | | | | | | | | | | | | | This was all using ArrayRef<>s before which presents a problem when you want to serialize to or deserialize from an actual PDB stream. An ArrayRef<> is really just a special case of what can be handled with StreamInterface though (e.g. by using a ByteStream), so changing this to use StreamInterface allows us to plug in a PDB stream and get all the record serialization and deserialization for free on a MappedBlockStream. Subsequent patches will try to remove TypeTableBuilder and TypeRecordBuilder in favor of class that operate on Streams as well, which should allow us to completely merge the reading and writing codepaths for both types and symbols.

* Remove LLVM_NOEXCEPT and replace it with noexceptReid Kleckner2016-10-191-1/+1
| | | | | | | Now that we have dropped MSVC 2013, all supported compilers support noexcept and we can drop this portability macro. llvm-svn: 284672
* Do not pass a superblock to PDBFileBuilder.Rui Ueyama2016-09-301-1/+3
| | | | | | | | | | | | | | | | | | | | | When we create a PDB file using PDBFileBuilder, the information in the superblock, such as the size of the resulting file, is not available. Previously, PDBFileBuilder::initialize took a superblock assuming that all the members of the struct are correct. That is useful when you want to restore the exact information from a YAML file, but that's probably the only use case in which that is useful. When we are creating a PDB file on the fly, we have to backfill the members. This patch redefines PDBFileBuilder::initialize to take only a block size. Now all the other members are left as default values, so that they'll be updated when commit() is called. Differential Revision: https://reviews.llvm.org/D25108 llvm-svn: 282944
* [pdb] Write TPI hash values to the TPI stream.Zachary Turner2016-09-141-5/+6

* [pdb] Print out some more info when dumping a raw stream.Zachary Turner2016-09-091-0/+4
| | | | | | | | | | | | | | | We have various command line options that print the type of a stream, the size of a stream, etc but nowhere that it can all be viewed together. Since a previous patch introduced the ability to dump the bytes of a stream, this seems like a good place to present a full view of the stream's properties including its size, what kind of data it represents, and the blocks it occupies. So I added the ability to print that information to the -stream-data command line option. llvm-svn: 281077
* [msf] Make FPM reader use MappedBlockStream.Zachary Turner2016-08-031-0/+29
| | | | | | | | | | | | | MappedBlockSTream can work with any sequence of block data where the ordering is specified by a list of block numbers. So rather than manually stitch them together in the case of the FPM, reuse this functionality so that we can treat the FPM as if it were contiguous.

* PDB: Mark extended file pages as free by default.Rui Ueyama2016-08-021-1/+1
| | | | | | | | | BitVector::extend initializes extended bits as true by default. That is not desirable because new pages should be initially free. Differential Revision: https://reviews.llvm.org/D23048 llvm-svn: 277529
* [msf] Resubmit "Rename Msf -> MSF".Zachary Turner2016-07-298-0/+980
| | | | | | | | | | | | | Previously this change was submitted from a Windows machine, so changes made to the case of filenames and directory names did not survive the commit, and as a result the CMake source file names and the on-disk file names did not match on case-sensitive file systems. I'm resubmitting this patch from a Linux system, which hopefully allows the case changes to make it through unfettered. llvm-svn: 277213

* [msf] Rename Msf to MSF.Zachary Turner2016-07-298-0/+980
In a previous patch, it was suggested to use all caps instead of rolling caps for initialisms, so this patch changes everything to do this. llvm-svn: 277190
