I believe that there is a general dislike of compiler intrinsic for vector
optimisations
Hi Lynne
I fully respect the policy and understand the disadvantages of intrinsic
code.
Considering the benefits of the open ISA like RISC-V,
the intrinsic code should still have a better chance of being optimized by
the compiler for hardware variants.
At this moment, the intrinsic implementation

You probably have access to proprietary performance information of
