[PATCH] D80580: Separate Peeling Properties into its own struct

[Sidharth Baveja via Phabricator via llvm-commits]

sidbav added a comment.

@fhahn I think a follow-up patch will take a little bit of time to develop so here is a quick example.

  for (i = 0; i < 10; ++i)
    a[i] = a[i] + 3;
  for (j = 1; j < 10; ++j)
    b[j] = b[j] + 5;

Here is we can make use of peeling, and then fuse the two loops together. We can peel off the 0th iteration of the loop i, and then combine loop i and j for i = 1 to 10.

  a[0] = a[0] +3;
  for (i = 1; i < 10; ++i) {
    a[i] = a[i] + 3;
    b[i] = b[i] + 5;
  }
