Description Christian Holler (:decoder) 2012-02-07 10:02:45 PST
The following testcase asserts on ionmonkey revision c34398f961e7 (run with --ion -n), tested on 64 bit:

function g() {}
for(var i = 0; "0 == 0"; i++) {
    g(0 || 1);
Comment 1 Nicolas B. Pierron [:nbp] 2012-02-07 10:16:58 PST
The fix should reuse the logic of IonBuilder::discardCallArgs (MCallOptimize).
I recently worked on it, so I take.

Share discardCallArgs function between Inlining and Native function substitution.
