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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@276458 91177308-0d34-0410-b5e6-96231b3b80d8
