Hi I was interested in working on this issue, I was wondering are there any tests available for this or should I be writing my own corresponding tests? Thank you!

Hi @mihir-b-shah,

Awesome. There are tests available but they are currently disabled. The existing tests are located here:

Other intrinsics-on-Mono work is being done right now, and by looking at some of these commits you should be able to get a feel for what you'll need to do. Here's an example:

Need #48475 to implement a subset of these

[mono] Implement Rdm and Dp (#49737)
4aeef0d 
See #42322 and
#42280.

Tested manually on an arm64 Linux VM running on an M1 Mac Mini. Does not
enable RDM or DP when AOT-compiling the associated runtime tests; our CI
hardware doesn't support these extensions yet.

Implemented in #49737.
