[PATCH] D109821: [ScalarEvolution] Infer loop max trip count from array accesses

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added a comment.

This can be useful also for loopunrollruntime, right?

For example:

  int data[6];
  
  int foo(void) {
    int p = 0;
    int i = 0;
    while (data[i++] != -1) // currently LLVM does not unroll this loop 6x like GCC does
       p += data[i];
    return p;
  }
