sorry to hear that, I haven't really been looking to much into
the debugging problems here yet. My extension mostly just
integrates the existing tools here (Visual Studio Debugger / GDB
+ whatever is emitted in the pdb files)
What I was talking about is that it's possible dmd didn't emit
the globals information in any way that the GDB / Visual Studio
Debugger understand right now. I'm not a debugger expert myself,
looking into this is probably something that would take a bit of
research about the DWARF / PDB formats and checking how DMD / LDC
emit it. I think you can probably get some great help here from
Martin Kinkelin. (I think the windows and linux debug info
emission works differently / are different modules, so there
might be discrepancies here)
I can help you point towards where to check and who to ask here,
but I don't think I can help you actually solve this issue right
now. I haven't really been focusing too much on the debugger,
especially not on the implementation of debug symbol emissions
and the debugger itself. I have only been adding a few scripts
here to get the best out the debugger that we currently have.
More things require more investment into actually improving the
project.
I'm quite glad about your contributions you have been doing so
far and I think the issues you are opening are good to find stuff
to work on. (the DCD PRs you have open right now are very nice
and appreciated, but need a bit of work still done to them before
they can be merged. I have reviewed them, but didn't have time to
actually make the changes and test them yet - if you want to get
these changes in faster you can also implement or reply to my
review comments)
Further people you could ask about here:
- Iain Buclaw (GDC developer), can probably tell you about what
gcc does here and possibly has insights into the D backend code
that generates debug info
- Martin Kinkelin (LDC developer), ditto
- Luís Ferreira (ljmf00 on discord) - has been working on LLDB
for SAoC and implementing a bunch of things - if things are
missing on the debugger side, he can probably help you with LLDB
implementations (you probably only need to go this far if we want
to add support for new custom data structure things that D has -
most things can already be realized with the debug symbols)
