+; The semanics of this example are a bit subtle.  The loop is required
+; execute some number of times up to 1999.  The compiler is free to reduce
+; the number of said iterations to zero (or any value in between) if desired,
+; but if it does so, the return value and the last value stored to G must
+; agree.  For SCEV, this translates as widenable conditions preventing exact
+; exit counts from being computed, but not restricting max exit counts.
+; It's tempting to say that SCEV should return a precise exit count here, but
+; would result in miscompiles if transformations such as RLEV ran before
+; widening of the WC.
