Nick Lewycky ce8bfeadff Make SCEV's brute force analysis stronger in two ways. Firstly, we should be 
able to constant fold load instructions where the argument is a constant.
Second, we should be able to watch multiple PHI nodes through the loop; this
patch only supports PHIs in loop headers, more can be done here.

With this patch, we now constant evaluate:
  static const int arr[] = {1, 2, 3, 4, 5};
  int test() {
    int sum = 0;
    for (int i = 0; i < 5; ++i) sum += arr[i];
    return sum;
  }

docs Revert r141657 for now. This has broken css and changed links on llvm.org. I'd like to understand exactly why the links have changed and if a newer doxygen is required. This may be reapplied once we upgrade on llvm.org and it is fully tested. 2011-10-21 20:51:54 +00:00
