            Bug ID: 126865
           Summary: [17 Regression] ICE at -O2 -march=rv64gcv on riscv64
                    during GIMPLE pass: slp
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xxs_chy at outlook dot com
  Target Milestone: ---

Reproducer: https://godbolt.org/z/53r7fsvz3
Reduced case:
#include <stdint.h>
#include <stdlib.h>
uint16_t g2, g24, g11;
_Bool g28_c11;
uint16_t g28()
{
    g24 = 10690 / (int16_t)g2;
    if (g28_c11) g11 = (int16_t)g28 / 9 + g24;
    abort();
}
