            Bug ID: 118942
           Summary: [14/15 Regression] vld1q_s{8,16}_x{3,4} use incorrect
                    pointer type
           Product: gcc
           Version: 14.2.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tnfchris at gcc dot gnu.org
  Target Milestone: ---
            Target: arm*

The follow intrinsics incorrectly take a pointer to unsigned rather than signed
data:

* vld1q_s8_x3
* vld1q_s16_x3
* vld1q_s8_x4
* vld1q_s16_x4

The non-q variants and other datatypes appear to be unaffected.

This is not according to the ACLE specs:
