            Bug ID: 96635
           Summary: Feature request: PDB support
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rafael_andreas at hotmail dot com
  Target Milestone: ---

A few years ago Microsoft has made parts of their PDB implementation public
(https://github.com/microsoft/microsoft-pdb), and PDB support is pretty much
complete in LLVM.
I think this is very useful information to implement PDB support in GCC and
further increase compatibility with the MSVC compiler.

The primary usecase for this feature is minidump support on Windows for post
mortem debugging. A user can write a crash reporting program that sends a
minidump over to the user's server(s) and then view the crash using WinDBG for
post mortem debugging. This feature will primarily be of interest to
organizations and companies, but is of interest to anybody wishing to increase
stability on Windows.

I think I may have seen some patches for this, but don't have the links on-hand
now...

The patches to support CodeView is being added (and improved) for GCC 15. I am
not sure how much will be finished by the release of GCC 15.

BUT it might be the case there is enough for at least minidump already.

Right, cc-ing Mark Harmstone, who has been the one submitting those patches.

Support for C is very nearly finished. I hope to get all the C++ stuff
(namespaces, templates, class member functions) done for GCC 15 too.

OK to put you as the assignee for this?
