Description
Description
These tests fail when upgraded to the new xunit based test system. This issue will be visible once #74886 is merged.
Reproduction Steps
Run the hardwareintrinsics_ro merged test project located in src/tests/JIT/HardwareIntrinsics/HardwareIntrinsics_ro.csproj
Expected behavior
Test should reliably pass.
Actual behavior
It fails where the difference in behavior is a floating point accuracy issue. (The algorithm is ... close in result) The expected result is within a small fraction of the actual result.
