            Bug ID: 112323
           Summary: aarch64: Missed operator support on ARM SVE intrinsic
                    type
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: juzhe.zhong at rivai dot ai
  Target Milestone: ---

Consider this following case:
#include "arm_sve.h"

svint8_t foo (svint8_t a, svint8_t b)
{
    return a + b;
}

https://godbolt.org/z/nMMxWcE4E

Clang is able to recognize "+" of svint8_t wheras GCC is not.

Any plan to support operator on ARM SVE type?

So the answer is no as far as I can tell. In fact:
(5) It makes it easier to ensure that (with default options) code is
    portable between compilers without the GNU vector extensions having
    to become an official part of the SVE intrinsics spec.

Is one of the big reasons.
Though (1) might be even better reason.

It is a bit odd that clang decided to go and implement it but this was a
conscious decision to reject it and gave reasons why.
