[llvm-pdbutil] Move InputFile/FormatUtil/LinePrinter to the PDB library.
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.
These callbacks look like they could actually be function_refs. Can you put a // TODO comment here to de-templatify them? I don't want to block on it.
