|
;; 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.
