If I understand correctly, then it may be fixed in 22.1.9 if it gets released. Thanks Jubilee for the quick reply there! Cc'ing Clang/LLVM build support, in case they didn't hear about it. I linked it in our usual lists. Cheers, Miguel ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks for the CC, I had not seen that issue. LLVM 22 is currently in the -rc phase and I see that the fix has been merged into the release/22.x branch as of yesterday so it should be in LLVM 21.1.0-rc3 when it get released on February 10. LLVM 21.1.8 was the last release of the 21.x series (hard to keep up with all the numbers...) and it sounds like this is only a regression from the LLVM 22 development cycle.

Yeah, sorry, mixed up 21.1.9 with the potential 22.1.9 in summer this year, bah! Fixed my comment in the issue to avoid confusion. Thanks!

Fixed as well for Rust 1.95.0 (expected 2026-04-16) when using the LLVM they provide. https://github.com/rust-lang/rust/pull/152428 Cheers, Miguel ^ permalink raw reply [flat|nested] 4+ messages in thread
