* [msf] Resubmit "Rename Msf -> MSF".Zachary Turner2016-07-298-980/+0
| | | | | | | | | | | | | 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 Turner2016-07-298-980/+0
| | | | | | | | 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

* Get rid of IMsfStreamData class.Zachary Turner2016-07-283-58/+31
| | | | | | | | | | | | | | | | | | | | This was a pure virtual base class whose purpose was to abstract away the notion of how you retrieve the layout of a discontiguous stream of blocks in an Msf file. This led to too many layers of abstraction making it difficult to figure out what was going on and extend things. Ultimately, a stream's layout is decided by its length and the array of block numbers that it lives on. So rather than have an abstract base class which can return this in any number of ways, it's more straightforward to simply store them as fields of a trivial struct, and also to give a more appropriate name. This patch does that. It renames IMsfStreamData to MsfStreamLayout, and deletes the 2 concrete implementations, DirectoryStreamData and IndexedStreamData. MsfStreamLayout is a trivial struct with the necessary data. llvm-svn: 277018
* Make PDBFile store an msf::Layout.Zachary Turner2016-07-221-11/+12
| | | | | | | | | | | Previously it was storing all the fields of an msf::Layout as separate members. This is a trivial cleanup to make it store an msf::Layout directly. This makes the code more readable since it becomes clear which fields of PDBFile are actually the msf specific layout information in a sea of other bookkeeping fields. llvm-svn: 276460
* [msf] Create LLVMDebugInfoMsfZachary Turner2016-07-2210-0/+1017
This provides a better layering of responsibilities among different aspects of PDB writing code. Some of the MSF related code was contained in CodeView, and some was in PDB prior to this. Further, we were often saying PDB when we meant MSF, and the two are actually independent of each other since in theory you can have other types of data besides PDB data in an MSF. So, this patch separates the MSF specific code into its own library, with no dependencies on anything else, and DebugInfoCodeView and DebugInfoPDB take dependencies on DebugInfoMsf. llvm-svn: 276458
