I have a single failure in the testing around invalid value tests. Will investigate and fix Monday. Otherwise ready for review. @dotnet/arm64-contrib @kunalspathak |

Removed this block as HWIntrinsicImmOpHelper does all those checks for you.

Tests are now all fixed. Issue was to ensure that all invalid values in the tests are actually out of range. (We treat 14 and 15 as in range values because the Arm instruction accepts them). I'm now happy with this PR. (Someone will have to fix up any review comments as I'm away now for a few weeks). |
Thanks for working on it. I will resolve merge conflicts and address any outstanding review comments. |

seems we missed adding this previously when we added other GatherVector APIs.

@a74nh - while testing something else, I realized that we are not validating the result in these tests.

Prefetch versions of the gather APIs. Essentially the same as gatherVector but has an extra enum and does not return anything.
