> Subject: [PATCH v3 07/15] arm: Implement MVE predicates as vectors of
> booleans
>
> This patch implements support for vectors of booleans to support MVE
> predicates, instead of HImode. Since the ABI mandates pred16_t (aka
> uint16_t) to represent predicates in intrinsics prototypes, we
> introduce a new "predicate" type qualifier so that we can map relevant
> builtins HImode arguments and return value to the appropriate vector
> of booleans (VxBI).
>
> We have to update test_vector_ops_duplicate, because it iterates using
> an offset in bytes, where we would need to iterate in bits: we stop
> iterating when we reach the end of the vector of booleans.
>
> In addition, we have to fix the underlying definition of vectors of
> booleans because ARM/MVE needs a different representation than
> AArch64/SVE. With ARM/MVE the 'true' bit is duplicated over the
> element size, so that a true element of V4BI is represented by
> '0b1111'. This patch updates the aarch64 definition of VNx*BI as
> needed.

The arm parts look ok. I guess Richard is best placed to approve the midend
parts, but I see he's on the ChangeLog so maybe he needs others to review them.
But then again Richard is maintainer of the gen* machinery that's the most
complicated part of the patch so he can self-approve 😊
Thanks,
Kyrill
