Description Jonas Rakebrandt 2024-05-12 22:26:56 UTC

The build fails with

> Traceback (most recent call last):
>   File "/var/tmp/portage/dev-lang/python-3.13.0_beta1_p1/work/Python-3.13.0b1/Tools/jit/_targets.py", line 164, in _compile
>     await _llvm.run("clang", args_ll, echo=self.verbose)
>   File "/var/tmp/portage/dev-lang/python-3.13.0_beta1_p1/work/Python-3.13.0b1/Tools/jit/_llvm.py", line 99, in run
>     raise RuntimeError(f"Can't find {tool}-{_LLVM_VERSION}!")
> RuntimeError: Can't find clang-18!

because the _LLVM_VERSION_PATTERN regex at https://github.com/python/cpython/blob/v3.13.0b1/Tools/jit/_llvm.py#L12 doesn't allow the +suffix.

Reproducible: Always

Steps to Reproduce:
1. Try building >=python-3.13 with USE=jit on a LLVM+libcxx system
Actual Results:  
Build fails due to mismatched version string

Expected Results:  
Build should succeed (and does when patching the _LLVM_VERSION_PATTERN)
