URL: https://github.com/llvm/llvm-project/commit/fc4df2c9173a110102005af937a26df7f29d24e1 DIFF: https://github.com/llvm/llvm-project/commit/fc4df2c9173a110102005af937a26df7f29d24e1.diff LOG: [win][arm64ec] XFAIL x64 intrinsic tests on Arm64EC (#153474) Clang defines the x64 preprocessor macro (`__x86_64__`) when building Arm64EC, however the tests for x64 built-ins and intrinsics are currently failing since the relevant functions don't exist, resulting in errors like: ``` Line 165: invalid conversion between vector type '__v2di' (vector of 2 'long long' values) and integer type 'int' of different size ``` (Clang doesn't know the intrinsics being called, and so treats it like an undefined function, which makes it assume the return type is `int`) For now, expect these tests to fail until someone decides to implement these intrinsics.
