New issue 3417 by [email protected]: When we fail to grow an array in new
space, maybe don't deopt
http://code.google.com/p/v8/issues/detail?id=3417
instead, we could use a stub that calls to runtime if we can't grow the
array inline
e.g. a loop like this:
<script>
var nodes = [];
var nodes2 = [];
for (var k = 0; k < 100; ++k) {
for (var i = 0; i < 1000 * 200 + 1000; ++i) {
a = document.createElement("div");
nodes.push(a);
nodes2.push(a);
}
}
</script>
will repeatedly deopt and eventually gives up optimizing.
