            Bug ID: 100306
           Summary: aarch64: ICE (output_operand: invalid expression as
                    operand) during final
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acoplan at gcc dot gnu.org
  Target Milestone: ---

The following (reduced from GROMACS 2021.1) fails:

$ cat test.c
typedef double c[3];
typedef int d[3];
typedef struct {
  d e;
} f;
typedef struct {
  f g;
  f h;
} i;
i j;
double k;
int l;
void w(void *);
void x(char);
void u(void *, void *);
void m() {
  char a[4096], n[4096], b[4096], o[4096], p[4096], s[4096], r[4096], t[4096];
  w(t);
  w(p);
  w(n);
  w(b);
  u(a, s);
  char v = r[0];

    w(q);
    w(o);
  }
  x(v);
  l = 0;
  for (; l < 3; l++) {
    j.g.e[l] = g[l];
    j.h.e[l] = k;
  }
}
