LLVM link for Windows 3/4/2025 + Setup info for first timer Windows Triton

[leomaxwell973]

Here is the official URL, link to the URL, as there is no official link afaik lol. For:
[a53431b](url) 3/4/2025
https://oaitriton.blob.core.windows.net/public/llvm-builds/llvm-a66376b0-windows-x64.tar.gz

to update your setup.py to recognize it post install (as well as install it post-download for you proper.)
~ln 224

# use_assert_enabled_llvm = check_env_flag("TRITON_USE_ASSERT_ENABLED_LLVM", "False")
    # release_suffix = "assert" if use_assert_enabled_llvm else "release"
    llvm_hash_path = os.path.join(get_base_dir(), "cmake", "llvm-hash.txt")
    with open(llvm_hash_path, "r") as llvm_hash_file:
        rev = llvm_hash_file.read(8)
    name = f"llvm-{rev}-{system_suffix}-x64"
    # Create a stable symlink that doesn't include revision
    sym_name = f"llvm-{system_suffix}"
    #url = f"https://oaitriton.blob.core.windows.net/public/llvm-builds/{name}-x64.tar.gz"  # <<< OLD URL Actual for reference, ITS SLOW!
    url = f"file:///C:/AI/LLVM/llvm-a66376b0-windows-x64.tar.gz"      # <<< Change this to somewhere you will LEAVE, it do not delete tzr.gz!
    return Package("llvm", name, url, "LLVM_INCLUDE_DIRS", "LLVM_LIBRARY_DIR", "LLVM_SYSPATH", sym_name=sym_name)

you will probably get an error on the windows version the first time you use it, unless you're pre--prepared.
as it looks for a version.txt in the sub-root
(%USERPROFILE%/.triton/llvm/llvm-a66376b0-windows-x64/*sub-root / aka "llvm-windows*)

where the folders start "llvm-windows" just put a version.txt there, i forget if that alone is enough but mine has:
file:///C:/AI/LLVM/llvm-a66376b0-windows-x64.tar.gz
dont remember if it was just a quick put anything in it, if it was a whim, or necessary but that's how mine is.

oh and dont forget to update you llvm package platforms in setup too

~ln 181

def get_llvm_package_info():
    system = platform.system()
    try:
        arch = {"x86_64": "x86_64", "arm64": "arm64", "aarch64": "arm64", "AMD64": "x86_64"}[platform.machine()]
    except KeyError:
        arch = platform.machine()
    if system == "Darwin":
        system_suffix = f"macos-{arch}"
    elif system == "Linux":
        if arch == 'arm64':
            system_suffix = 'ubuntu-arm64'
    elif system == "Windows":
        if arch == 'x86_64':
            system_suffix = 'windows'
    elif system == "Win32":
        if arch == 'x86_64':
            system_suffix = 'windows'
        elif arch == 'x64':
            vglibc = tuple(map(int, platform.libc_ver()[1].split('.')))
            vglibc = vglibc[0] * 100 + vglibc[1]

(Might be sloppy but it works. for windows at least.)

That should be the bulk of getting your foot in the door for getting unofficially recognized as a supported platform as a windows user.
There will probably be lots of bugs and failed builds/installs, but that is beyond the scope of this post.

Thank you for discovering this! I've added this to my fork in the recent commits of main-windows branch: woct0rdho@d91879e

I'm troubleshooting a stubborn cache, or whatever, and redownloaded myself some tips:

You can always get the most up to date link by simply replacing the hash in the project, located at the Triton(root)/cmake/llvm-hash.txt, but only the first eight numbers/letters.

and when updating the URL, idk how but i forgot the "llvm-builds" entirely.. probably since I copied my URL:FLE: link, instead of the reference lol, why its there :P

LASTLY VERY IMPOTANT: the URL, lest the filename is case sensitive do all lower; else = not found.
