Closed Bug 767750 Opened 7 years ago Closed 7 years ago
With bug 765956, I think we can remove JSScript::evalHashLink by using a Vector in the eval cache instead of embedding the link. This would save a word and make njn smile.
Might as well. Plus, the eval cache logic was bothering me so I turned it into a proper HashSet. A few notes: - evalCache is cleared on every GC - compartment now implies principals (CPG) which is why I replaced the principals subsumption check with compartment equality - that EvalKernel assert I removed is already in DirectEval

Unfortunately bug 772303 (https://hg.mozilla.org/integration/mozilla-inbound/rev/fad7d06d7dd5) had to be backed out for winxp pgo-only jsreftest failures. This bug (amongst others) either caused unresolvable (for someone who doesn't work on the JS engine at least) conflicts with the backout of fad7d06d7dd5, or else bugzilla dependencies indicated that one of it's dependants had now been backed out. Since there was no one in #developers that could resolve the conflicts, unfortunately this bug has been backed out: https://hg.mozilla.org/integration/mozilla-inbound/rev/f0be4b70b814
