--- Comment #7 from Charles Greathouse <gcc at crg4 dot com> ---
Here's a testcase which fails without -fcheck-data-deps. Run
gcc5.1 testcase.c -O2 -ftree-loop-linear -floop-strip-mine
to reproduce:
typedef struct m {
const char * s1;
const char * s2;
} mystruct;
mystruct arr[52];
void main() {}
void generateICE(void) {
int i;
for(i=0; i<52; i++) {
arr[i].s1 = "";
arr[i].s2 = 0;
}
}
