Incompatibility with llvmlite 0.45.0: AttributeError: module 'llvmlite.binding' has no attribute 'PassManagerBuilder'

[hanlaur]

Hello and thanks for this magnificent module!

There appears to be a breaking change in llvmlite 0.45.0 that impacts lleaves:

• https://github.com/numba/llvmlite/blob/main/CHANGE_LOG
• https://llvmlite.readthedocs.io/en/latest/user-guide/llvm20.html

Example error:

    def compile_to_module(
        file_path,
        fblocksize=34,
        finline=True,
        raw_score=False,
        froot_func_name="forest_root",
        use_fp64=True,
    ):
        forest = parse_to_ast(file_path)
        forest.raw_score = raw_score
    
        ir = llvmlite.ir.Module(name="forest")
        gen_forest(forest, ir, fblocksize, froot_func_name, use_fp64)
    
        ir.triple = llvm.get_process_triple()
        module = llvm.parse_assembly(str(ir))
        module.name = str(file_path)
        module.verify()
    
        if os.environ.get("LLEAVES_PRINT_UNOPTIMIZED_IR") == "1":
            print(module)
    
        # Create optimizer
>       pmb = llvm.PassManagerBuilder()
              ^^^^^^^^^^^^^^^^^^^^^^^
E       AttributeError: module 'llvmlite.binding' has no attribute 'PassManagerBuilder'

This can at the moment be solved by pinning llvmlite to 0.44.0, but probably good to handle this in lleaves in future.

Can you send a PR? Else I'll ask @claude to send one when I get around to it

I see you have merged PR for this so the support should become available when you make the next PyPi release. Thanks @siboehm for making the the updates! I would have not felt comfortable making those without familiarizing well with the LLVM concepts and library.

Hi @siboehm, it looks like the PyPI release GHA run back in October was unsuccessful. Do you think you could find time to publish the release with the compatibility fix to PyPI anytime soon?
