@llvm/clang-vendors Adding clang vendors. FYI, this change expands error reporting on invalid version numbers to all target triples (This was previously restricted to Android triples). This can have potential downstream impact. Please review/test and let us know if this breaks any valid usages.

A better title may be:

[Driver] Report invalid target triple versions for all environment types.

"Driver" is better than "clang" as it is specific about where the error arises.

This broke the wasi-threads target:
clang: error: version 'threads' in target triple 'wasm32-unknown-wasi-threads' is invalid

…pes. (llvm#78655) Followup for llvm#75373 1. Make this feature not just available for android, but everyone. 2. Correct some target triples. 3. Add opencl to the environment type list.

ZijunZhaoCCK · 2024-02-05T23:00:09Z

This broke the wasi-threads target: clang: error: version 'threads' in target triple 'wasm32-unknown-wasi-threads' is invalid

Because threads is not in EnvironmentType list: https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/TargetParser/Triple.h#L231 or ObjectType list: https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/TargetParser/Triple.h#L284 .

The format should be arch-vendor-os-env. If threads is a new environment type, please add it in the list. If wasi-threads is a special case, please let me know!

And one more question, would you mind pointing me out the test case of wasm32-unknown-wasi-threads ? I don't see it. Thank you!

glandium · 2024-02-05T23:16:47Z

We stumbled upon this downstream because we have jobs building wasi-sdk with clang-trunk, and wasi-sdk builds some things with that target. It apparently comes from WebAssembly/wasi-libc#381

glandium · 2024-02-05T23:18:16Z

There's apparently also wasm32-wasi-preview2 and wasm32-wasi-pthread, which I suppose are equally broken by this change.

Yes, I think so. I think adding these environment types in wasi-libc repo could help fix those errors.

Yes, I think so. I think adding these environment types in wasi-libc repo could help fix those errors.

If wasm can arbitrary environment types, it seems that we can opt out the check for isWasm().
We define new environment types when they affect the compiler behavior. If wasm arbitrary sets the environment, we should not define a type for each one.

Okay, I will add this check.

Add isWasm() check for here: #78655 (comment)

This updates the HLSL invalid environment tests to adapt to llvm#78655.
