Hi Amara,
thank you for the clarification. I tested the intrinsics x86_64 and it
seemed to work pretty well. Looking forward to try this intrinsics with
the AArch64 backend. Maybe I find the time to look into codegen to get
this intrinsics out of experimental stage. They seem pretty useful.
Cheers,
Michael
