            Bug ID: 96914
           Summary: missing MVE intrinsics
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---

Applying the same process as in PR71233, I have noticed a few MVE intrinsics
are not implemented:
__arm_vcvtnq_u32_f32
__arm_vqdmlashq_m_n_s16
__arm_vqdmlashq_m_n_s32
__arm_vqdmlashq_m_n_s8
__arm_vqdmlashq_n_s16
__arm_vqdmlashq_n_s32
__arm_vqdmlashq_n_s8


FTR, I downloaded the full list from
https://developer.arm.com/architectures/instruction-sets/simd-isas/helium/helium-intrinsics
I parsed it with the same script provided in PR71233, I preprocessed a sample
hello-mve.c containing only:
#include <arm_mve.h>
with -mcpu=cortex-m55 -mfloat-abi=hard
and checked if any of the intrinsics defined in the doc was missing from the
preprocessed hello-mve.i, after removing the brackets from intrinsic names such
as [__arm_]vidupq_x[_n]_u16

This results in the short list above.
