GGC was enabled yesterday (2014-Sep-15) on b2g-inbound with bug 1020751. It has not yet been merged into mozilla-central, but I expect it will be soon. GGC is already on desktop Firefox, and in fact just shipped with Firefox 32. Keep an eye out for regressions on FxOS. Or improvements, for that matter -- we'd be interested in any real-world workloads that see significant changes.
Also note that exact rooting is now enabled everywhere, and has been for some time. The conservative collector has been removed (bug 914402). Mobile Firefox does not yet use the generational collector, for no particular reason. I will likely be turning that on shortly (though we'll see what the try server has to say about it first!) _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
