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