1170596 - IonGraph not working anymore on functions which contain infinite loops

Status: RESOLVED FIXED

(Core :: JavaScript Engine: JIT, defect)

Description

[Benjamin Bouvier [:bbouvier] (inactive)]

I've tried both IONFLAGS=logs, and IONFLAGS=logs-sync with --ion-offthread-compile=off, without success. The smallest test case I have is a function which contains an infinite loop:


function module() {
    'use asm';
    function f() {
        var x = 42;
        while ((x|0) > 32) {
        }
    }
    return f;
};
module()();

This is a work-around, I will try to come with a cleaner patch, as we
probably don't want to flsuh all the time.

Thanks! It fixed the issue I saw when debugging a rather large asm.js module.
