            Bug ID: 97693
           Summary: [11 Regression] SVE: ICE in prepare_load_store_mask,
                    at tree-vect-stmts.c since r11-1143-gb05d5563
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acoplan at gcc dot gnu.org
  Target Milestone: ---

For the following C testcase:

extern short a[];
int b;
short c, d;
unsigned e() {
  if (c)
    return c;
  return d;
}
void f() {
  for (unsigned g = b; g; g += 6)
    for (_Bool h = 0; h < (_Bool)e(); h = 1)
      a[g] = 1 / b;
}

AArch64 GCC ICEs with -O3 -march=armv8.2-a+sve since
r11-1143-gb05d5563f4be13b4a0d0951375a82adf483973c0. To reproduce:

$ aarch64-elf-gcc -c -O3 -march=armv8.2-a+sve test.c
