I'm still confused by the way it's become fashionable lately to bash optimizing compilers, of all things. They're important!
@cr88192 @scottmichaud @pcwalton These "common assumptions" (esp. in relation to aliasing) are wrong and preclude all vectorization.

@RichFelker@scottmichaud@pcwalton granted, I was talking more about violating assumptions WRT integer arithmetic than about aliasing. -
@cr88192@richfelker@scottmichaud You need to know the loop trip count for autovectorization too. -
@pcwalton@RichFelker@scottmichaud granted, in general but this shouldn't require changing the behavior of signed integer arithmetic ops.
