I have a question regarding the vectorizer. In the following code below...
Int func (int x, int y)
If we force the x and y to be vectors of vectorlength 4, then will the if-statement get a vector of booleans or does it get 1 boolean that compares 2 very large values? I guess another way to ask is that, will it logically break it up into 4 if-statements or just 1?
Any help is greatly appreciated!

PS. Please CC me in response so that I can get to it quickly.
return x==y ? x+y : x-y;
