The mingw toolchain produces PE binaries with DWARF in them. I'm not 100% sure how it works, but it should be possible to support with gimli+object. This is a follow-on from #39 .

@jon-turney has submitted patches to Breakpad to support this use case, maybe he can point us at some resources that explain what mingw does.

Specifically, there's this patchset that adds support for dumping symbol information from mingw PE files: https://codereview.chromium.org/1451693003/

I'm not sure there's much to explain. The same DWARF information sections are present, but the container is PECOFF rather than ELF.

Issue gimli-rs#40 -- Support DWARF-in-PE
fcb8002 
DWARF sections names in PE files are stored indirectly through a symbol table.
Names of the form "/n" where "n" is a number indicate the section name is
stored in index "n" of a hidden symbol table.  The hidden symbol table immediately
follows the COFF symbol table and is a sequence of null terminated CStrings.
