Description

10 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; nl; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2a1pre) Gecko/20090117 Minefield/3.2a1pre

Reverse Sparse Native Array, "var i = sarr.length-1; do { } while (i--);" and "for loop in reverse.	for (var i=sarr.length; i--;) { }" and "for ... in loop	for (var i in sarr) { }" no longer speed up with JIT enabled.

In "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2a1pre) Gecko/20081227 Minefield/3.2a1pre" it did speed up, ran 80ms with jit off, 40 with jit on. In "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2a1pre) Gecko/20090117 Minefield/3.2a1pre" it runs 70ms with jit either on or off.

Reproducible: Always

I'm confused, tried to find a better regression range, and now i can't find the entire problem any more at all. Even my testcase was working before, guess a reboot was enough to get back to this.
