llvm-mirror/lib/DebugInfo/CodeView/DebugFrameDataSubsection.cpp
Zachary Turner 4006e15ad2 [CodeView] Add more DebugSubsection implementations.
This adds implementations for Symbols and FrameData, and renames
the existing codeview::StringTable class to conform to the
DebugSectionStringTable convention.
