            Bug ID: 99469
           Summary: ICE: qsort checking failed with selective scheduling
                    on aarch64
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acoplan at gcc dot gnu.org
  Target Milestone: ---

The following fails:

$ cat test.c
typedef struct {
  int a[3];
} s;
s ss[1][5][8];

int g();
void h(s);
int foo(char *, ...);

void f() {
  int a, b, c, d = 0;
  if (g())
    d = 1;
  for (; a; a++) {
    if (d)
      foo("a", "");
    h(ss[a][b][c]);
    if (d)
      foo("a");
  }
}

$ aarch64-linux-gnu-gcc -c test.c -O2 -fselective-scheduling
-fselective-scheduling2 -fsel-sched-pipelining -mtune=cortex-a53
