Description Sam James archtester

2024-08-03 02:01:16 UTC

Created attachment 898826 [details, diff]
gcc15-x86.patch

I've fixed this upstream already.

We need three patches:
1) https://github.com/llvm/llvm-project/commit/7e44305041d96b064c197216b931ae3917a34ac1
2) https://github.com/llvm/llvm-project/pull/101766
3) Attached patch (only needed for <19, so no upstream PR, it'll be handled by the backport of 1))

Note that unfortunately it fixes an installed header so a revbump is needed.
