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. Cheers, Nathan
