Change SmartMove no-op behavior to match SimpleMove (and ES6 spec) · f3c36975

adamk@chromium.org authored Oct 23, 2014

The previous behavior, which caused Array.prototype.unshift() (with no args)
to have side-effects, no longer matches the spec (ES6 changed the no-arg behavior
in April 2014). The new SmartMove behavior is also compatible with current
versions of Firefox.

This is a baby step towards getting rid of SmartMove; it isolates the test
change in this patch, instead of lumping it in confusingly with all the
other test updates necessary for moving away from SmartMove.

[turbofan] Use range types to type and lower arithmetic ops. · c7685a59

jarin@chromium.org authored Oct 23, 2014

This is based on Georg's work on typing arithmetic operations (https://codereview.chromium.org/658743002/).

Instead of weakening to bitset types, we weaken to the closest 2^n
limit if we see that we are re-typing a node with a range type (which
means that the node can be part of a cycle, so we might need
to speed up the fixpoint there).
