Compiling the following test results in an ICE:

/* arm-systest-eabi-gcc -c -O3 -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=softfp
test.c */
typedef signed char int8_t;
typedef signed long long int64_t;
int64_t
f0a (int8_t * __restrict__ arg1)
{
int idx;
int64_t result = 0;
for (idx = 0; idx < 416; idx += 1)
result += arg1[idx] << (arg1[idx] == arg1[idx]);
return result;
}
/* End of test.c. */
$ arm-upstream-eabi-gcc -c test.c -O3
