At Sony we are developing llvm-dva https://lists.llvm.org/pipermail/llvm-dev/2020-August/144174.html For its PDB support, it requires functionality already present in llvm-pdbutil. We intend to move that functionaly into the PDB library to be shared by both tools. That change will be done in 2 steps, that will be submitted as 2 patches: (1) Replace 'ExitOnError' with explicit error handling. (2) Move the intended shared code to the PDB library. Patch for step (1): https://reviews.llvm.org/D121801 This patch is for step (2). Move InputFile.cpp[h], FormatUtil.cpp[h] and LinePrinter.cpp[h] files to the debug PDB library. It exposes the following functionality that can be used by tools: - Open a PDB file. - Get module debug stream. - Traverse module sections. - Traverse module subsections. Most of the needed functionality is in InputFile, but there are dependencies from LinePrinter and FormatUtil. Some other functionality is in the following functions in DumpOutputStyle.cpp file: - iterateModuleSubsections - getModuleDebugStream - iterateOneModule - iterateSymbolGroups - iterateModuleSubsections Only these specific functions from DumpOutputStyle are moved to the PDB library.
