I hit the same issue with nodejs-22.1.0 with 18.1.5; it previously built fine with 18.1.4, though. Another, smaller package I'm hitting this with is highway-1.0.7.

This only happens with -march=native; things build fine with -march=alderlake on my i9-12900KS, so this is probably about feature mis-detection.

I'll downgrade to 18.1.4, verify things work again and check what native expands to, if I can pinpoint anything specific...

Thanks for ruling out 18.1.4, I'll update the title

There's only 30 commits between 18.1.4. and 18.1.5 llvmorg-18.1.4...llvmorg-18.1.5

I was just going to point at the same commit as the possible culprit here, yes.

I'm reverting it locally, will see if that fixes things

This has affected compiling libreoffice and nodejs so far. Clang 18.1.3 built these packages fine, so I think the change was added in 18.1.4 or 18.1.5 - which seems strange as I'd expect only bug fixes
