Description
ExecuTorch doesn't build with MSVC. It has a ton of compiler errors that require significant effort to fix. It requires clang to compile. Our current Windows machines in CI do no have clang installed with MSVC. To support building and testing ET on Windows in CI, we need to support clang + MSVC.
The change to enable in Windows AMI has been landed: https://github.com/pytorch/test-infra/pull/6654 . The clang enablement was validated in canary using this PR: https://github.com/pytorch/pytorch-canary/pull/255
AMI is not fully tested in canary yet and not ready to be part of production yet.
