            Bug ID: 97326
           Summary: [11 Regression] s390: ICE in do_store_flag after
                    10843f830350
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: iii at linux dot ibm.com
  Target Milestone: ---

The following (minimized from
gcc/testsuite/gcc.target/s390/zvector/autovec-double-signaling-eq.c) produces
an ICE on s390:

build$ cat x.c
long *a;
double *b;
c;
d() {
  for (; c; c++)
    a[c] = 0 <= b[c] && 0 >= b[c];
}

build$ gcc/cc1 -O3 -march=z15 x.c
during RTL pass: expand

x.c: In function 'd':
