Latest dev version (a642651) hangs forever on link.exe

[frederikhors]

Tried today the latest dev version and the cargo-clif build`` is stopping on link.exe` forever!

I'm coming from cargo 1.85.0-nightly (769f622e1 2024-12-14) that works OK.

I'm on Microsoft 14.42.34433.0, Windows 11.

I'm afraid I don't have a clue what could be going on. Maybe if you can bisect it to the exact commit that introduced this issue that would help explain it? If you don't want to build cg_clif locally, you can download the CI artifacts for a specific commit from https://github.com/rust-lang/rustc_codegen_cranelift/actions/workflows/main.yml?query=branch%3Amaster If you click on the CI run for the commit in question, you can scroll down to the bottom to see the release artifacts. Github only keeps them for a relatively limited amount of time, though I expect the artifacts for 2024-12-14 to still exist.

Actually maybe 4cc1c90 is the offending commit? Can you check if it works on the commit before this and breaks with this commit?

[frederikhors]

4cc1c90 has the issue. Plus it's very, very, very slower before arriving to the last crate (when it calls link.exe).

7f98f34 doesn't have the problem. And it works with similar timing to the commit I've been using so far.

Thanks for confirming that 4cc1c90 is the issue. Would you mind testing #1554? This disables -Zfunction-section again, but only on Windows.

[frederikhors]

I'll try it when it's ready.

[bjorn3]

It is ready. The last push to the PR was just a cosmetic thing. CI failure on FreeBSD exists on master too. Something broke on the rustc side.

[frederikhors]

I tried msvc bundle from https://github.com/rust-lang/rustc_codegen_cranelift/actions/runs/12772502374.

It works!

Opened rust-lang/rust#135776 to sync the fix to the rust repo.
