[LLVMdev] How to make Polly ignore some non-affine memory accesses
...,k,h;
const int x = 0, y=0;
B = (char *)malloc(sizeof(char)*1024*1024);
for (i = 1; i < 1024; i++)
for (j = 1; j < 1024; j++)

if (i+j > 1000)
B[j] = i;
}
printf("Random Value: %d", B[rand() % 1024*1024]);

running:
opt -load ${PATH_TO_POLLY_LIB}/LLVMPolly.dylib -polly-scops -analyze

I get:
