Updated to add vectorization and unrolling factors to the output (this can be disabled by passing -s). So the output now looks like this:

  < /tmp/v.c
   2          | void bar();
   3          | void foo() { bar(); }
   4          |
   5          | void Test(int *res, int *c, int *d, int *p, int n) {
   6          |   int i;
   7          |
   8          | #pragma clang loop vectorize(assume_safety)
   9     V4,2 |   for (i = 0; i < 1600; i++) {
  10          |     res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
  11          |   }
  12          |
  13  U16     |   for (i = 0; i < 16; i++) {
  14          |     res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
  15          |   }
  16          |
  17 I        |   foo();
  18          |
  19          |   foo(); bar(); foo();
     I        |   ^
     I        |                 ^
  20          | }
