llvm dev - May 2019 - Require support to use LLVM's PDB classes and pdbutil

Hello,
I'm trying to parse debug information out of PDB files that's created by
visual studio, and also maybe producing stacktrace on linux.
Does anyone has leads to how I can do that with LLVM's pdbutil? Or point me
to a documentation about that?

Thanks.

I would say that llvm-pdbutil mainly exists to dump PDBs as human readable
text, and to translate them to and from YAML. As far as interpreting the
contents of the PDB to do something useful, like produce a stack trace,
goes, the consumer of LLVM's PDB reading libraries is responsible for doing
that. For example, LLDB at some point will likely implement stack unwinding
with unwind data from PDBs.

I don't think we have any existing documentation or references for coding
against the LLVM native PDB reading APIs, but you can look at the code in
LLDB to get an idea for how it can be done.

I'd start with reading the documentation about PDB file format, described
here:  https://llvm.org/docs/PDB/index.html

There's a lot there, but if you want to interpret the contents on your own
(even using LLVM's PDB libraries to do the low level work) you're going
to
need to understand it.

Once you have a basic understanding of what goes into a PDB file and how
it's organized, LLVM's PDB APIs should (hopefully) be fairly
self-explanatory and you can read the code of llvm-pdbutil to see how it
does various things, which you can copy.
