            Bug ID: 109481
           Summary: Bug in openEuler/gcc (13.0.1) support for ARM SVE
                    openmp
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wumingchuan1992 at foxmail dot com
  Target Milestone: ---

demo.c
#include <stdio.h>
#include <stdlib.h>
#include "arm_sve.h"

void test(const int len, const float *src, float *dst)
{
int loop = svcntw();
svbool_t pg = svptrue_b32();
#pragma omp parallel for
for (int i = 0; i <= len - loop; i += loop) {
svfloat32_t x = svld1_f32(pg, src + i);
svfloat32_t y = svadd_f32_x(pg, x, x);
svst1_f32(pg, dst + i, y);
}
}

int main()
{
float src[512] = {0};
float dst[512] = {0};
test(512, src, dst);
return 0;
}

Run gcc(10.3.0 and 13.0.1 20230412) with the following command:
$ gcc -std=c99 -O2 -fopenmp -march=armv8.3-a+fp+sve -o demo.exe demo.c

After the command is executed, the following information is displayed:

demo.c: In function ‘test’:
demo.c:11:25: internal compiler error: Segmentation fault
11 | svfloat32_t x = svld1_f32(pg, src + i);
   |                 ^~~~~~~~~~~~~~~~~~~~~~

        ../../gcc/gimplify.cc:7994

Any suggestions to proceed?

Looks like a dup of PR101018.
