Now, I understand how to call foldsTo function. But I can't still fix this bug(https://bugzilla.mozilla.org/show_bug.cgi?id=852791) When I type: var s = "hoge" + x + "fuga" ,ValueNumberer::simplify or ValueNumberer::simplifyControlInstruction always call MDefinition::foldsTo(bool useValueNumbers).
I predict MStringLength::foldsTo is called when string constants is folded. But MStringLength::foldsTo isn't call. What function call when string constants is folded. _______________________________________________ dev-tech-js-engine-internals mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-js-engine-internals
