bootstrap: refactor mingw dist and fix gnullvm #144659

mati865 · 2025-07-29T23:15:54Z

The first two commits are NFC and only clean up the code, paving the way for the third commit. That said, I think they are worthwhile even without that fix - reusing the same function for two different outcomes was confusing.

The third commit is the fix for #144533, but due to the cross-compilation dance it requires a workaround to find the DLL since that logic really was meant only for Windows builders. That workaround is short-lived and will be removed as soon as gnullvm bootstraps itself.

Also including regular windows-gnu to double-check there is no regression there.

I hope this clearly (albeit in a lengthy way) shows no regression for *windows-gnu toolchains and the fix for windows-gnullvm toolchains.

Judging by their profile albertlarsan68 seems to be away right now, so I will take a liberty to reroll because the release is near and this might get backported for the next beta.

I would spell gnullvm explicitly here, to make it more obvious which targets need libunwind.dll.

Nominating for the backport to beta, @rustbot modify labels: +beta-nominated

This fixes the issue with gnullvm host toolchain failing to start when the user doesn't add libunwind.dll to their PATH environment variable. Depending on the setup, it might be a natural thing (first dot) to do or not so much (the other two):

When C toolchain puts libunwind.dll next to the Clang binary, like in MSYS2 case, adding Clang to PATH also adds the library.
When C toolchain uses wrappers as the "entry points" it might put both Clang and the library into a different directory. This can be seen in llvm-mingw which is probably the best known LLVM based mingw-w64 toolchain. In this case, the user typically adds only the wrappers to PATH.
Regardless of the toolchain, if the user doesn't modify PATH but configures the linker via Cargo config or other environment variables

I can see the following ways to improve this situation:

Backport this PR - this fully fixes the problem, but since this PR refactors code used by Tier 1 windows-gnu target, this might be deemed too risky.
Create smaller version of this PR only for the beta - also fixes the problem but is probably even less feasible.
Update release notes with the workaround - basically mention the bug and tell how to work around it.
Drop gnullvm hosts from beta (and future stable) - delay the "release" of these host toolchains by one release, proposed in the issue

This proposal is the first option. I think it'd be the least problematic, but I'm open to all options (mentioned above or not).

@mati865 this was being discussed in #t-infra/bootstrap/backports > #144659: beta-nominated. I think the current vibe is towards delaying gnullvm host tools by a release cycle. WDYT?

If you're also on-board, I think we need to do the host tool availability change against beta and also against master, right?

mati865 · 2025-08-13T06:02:54Z

@jieyouxu it's not a problem for me. I think it'd be enough to disable gnullvm CI jobs from beta. Should I do it?

@jieyouxu it's not a problem for me. I think it'd be enough to disable gnullvm CI jobs from beta. Should I do it?

Hm, it's Tier 2 right, so we can't just completely disable it? Or do you mean host tools specifically?

mati865 · 2025-08-13T15:15:31Z

Yeah, I meant disabling (removing) the new Dockerfile jobs and restoring changes to the dist-various. Effectively reverting #140772 and #143031 but it will probably have conflicts.
