Make OpenCL an OSType rather than an EnvironmentType. #170297

maarquitos14 · 2025-12-02T14:39:23Z

OpenCL was added as an EnvironmentType in #78655, but there is no explanation as to why it was added as such, even after explicitly asking in the PR (#78655 (comment)). This PR makes it an OSType instead, which feels more natural, and updates tests accordingly.

Adding a couple of references to PRs where this was discussed/suggested:

[SPIRV] Change how to detect OpenCL/Vulkan Env and update tests accordingly. #129689 (comment)
[SPIRV] Addition of @llvm.lround.* and @llvm.llround.* intrinsic #129240 (comment)

github-actions · 2025-12-02T15:25:53Z

🐧 Linux x64 Test Results

193467 tests passed
6228 tests skipped

✅ The build succeeded and all tests passed.

bader

Test changes imply that AMD team is using the OpenCL EnvironmentType.
@yxsamliu, are you okay with this change?

Test changes imply that AMD team is using the OpenCL EnvironmentType. @yxsamliu, are you okay with this change?

Yes, thanks for tagging somebody. I was planning to ask if anybody from AMD could have a look at this. I suspect OpenCL was originally added as EnvironmentType because of these tests. Likely, the patch was failing for these tests, and they added it as EnvironmentType to fix errors.

arsenm · 2025-12-02T17:18:51Z

OpenCL should be neither an operating system or an environment. It's a source language, not a target ABI. I think we used to mishandle HIP and OpenCL differences and I don't think AMD is using this anymore

There must be some feature to separate GPU code execution environments (e.g. OpenCL and Vulkan). @arsenm, do you have a constructive proposal to separate them?
