Current parallel iv optimization only happens in an int counted loop with int-typed parallel iv's. Optimization for the following code should be considered:
private static long testIntCountedLoopWithLongIv(int stop) {
long a = 0; // <-- typed long
for (int i = 0; i < stop; i++) {
a += 42; // <-- 42 is a long constant
}
return a;
}
where the value of `a` should be eventually optimized to a constant time operation dependent on `stop`.
private static long testIntCountedLoopWithLongIv(int stop) {
long a = 0; // <-- typed long
for (int i = 0; i < stop; i++) {
a += 42; // <-- 42 is a long constant
}
return a;
}
where the value of `a` should be eventually optimized to a constant time operation dependent on `stop`.
