LLDB support? about llvm-mingw

[mstorsjo]

FWIW, I released a new version now, and this build now includes LLDB.

[mstorsjo]

Yes, LLDB kind of should work. I've been working lately on making sure it works to build in a mingw setup, and to make it work for arm and arm64 as well (or at least compiles):
llvm/llvm-project@f4deacf
llvm/llvm-project@2e25c44
llvm/llvm-project@8969f8d
llvm/llvm-project@fb31852
llvm/llvm-project@8b98f12
llvm/llvm-project@638f072
llvm/llvm-project@02dddfd
llvm/llvm-project@b1f6ba2
(and a couple more)

There's still a few bits left before I'd prefer to enable it in my builds, because right now building still fails for arm32 because some bits are unimplemented. I could of course spend some extra effort to only enable lldb for i686/x86_64/arm64, complicating build-llvm.sh even more, but it's not far away to have it building nicely on all four architectures now.

Is it possible to include lldb-mi? Then it should work with vscode-cpptools without Python support

[mstorsjo]

Hmm, lldb-mi seems to have been split out to a standalone repo, so it's a bit more hassle, but I guess it should be doable.

The main lldb repo does contain a tool called lldb-vscode though. Is that useful for the same purpose, or does it do something entirely different?

[vitalyster]

That tool require lldb with Python if I understand right, but yes it should be for the same purpose

I checked lldb-vscode more carefully - looks like it does not need Python (it is third tool of the same type), should be great to include there instead of lldb-mi

[mstorsjo]

Try https://martin.st/temp/llvm-mingw-x86_64-vscode.zip, which has lldb-vscode.exe included.

[vitalyster]

Thanks, I tested it but it does not work correctly, seems it needs collaboration with their developers/maintainers

[mstorsjo]

Ok.

I tested building lldb-mi now, but it doesn't seem to support building for windows (not sure how much or little work is needed on it) - so my suggestion would be to try to figure out what the status of lldb-vscode is and how to make it work.

Apparently lldb-mi is included in the public releases of llvm for windows, so it should be supported, so it could be something in how I'm setting up my build, or it could be some recent breakage.

If you want to try that out, you could get the prebuilt versions of it from https://releases.llvm.org/download.html#9.0.0. Do note that the lldb parts of it require you to have exactly python36.dll available for it to run at all.

Some upgrade regarding lldb-mi:
Upstream has fixed building lldb-mi on mingw targets lldb-tools/lldb-mi#52, so if you feel like checking out another repo then give it a try

In #83 (comment) you mentioned that even if you managed to build lldb-mi, it didn't seem to work/do anything useful in vscode - has this changed, or are you just wanting to test a newer build (or use it with another IDE)?

[SquallATF]

I have build latest lldb-mi with latest release/11.x branch, it can works with vscode c++ extension.

[longnguyen2004]

I'm not sure if it works with VSCode now, and I don't really need it to work anyway, since VSCode has its own way of doing it (the Debug Adapter Protocol, which works wonderfully), so this is mainly for users with other IDE (like Qt Creator)

[mstorsjo]

I looked into getting lldb-mi built as part of this - and https://martin.st/temp/llvm-mingw-11-test-x86_64.zip is a test build including it. Does it seem to work and do something meaningful for anyone?

[longnguyen2004]

I know someone who can help
@RussellHaley Can you please test lldb-mi in this package?
