| ;; Date: May 28, 2003. |
| ;; From: test/Programs/MultiSource/Olden-perimeter/maketree.c |
| ;; Function: int CheckOutside(int x, int y) |
| ;; |
| ;; Note: The .ll code below for this regression test has identical |
| ;; behavior to the above function up to the error, but then prints |
| ;; true/false on the two branches. |
| ;; |
| ;; Error: llc generates a branch-on-xcc instead of branch-on-icc, which |
| ;; is wrong because the value being compared (int euclid = x*x + y*y) |
| ;; overflows, so that the 64-bit and 32-bit compares are not equal. |
