_Evaluate UCIn Stack Frame should not be expected to extend all call objects
At the moment, we have tests that expect JS_EvaluateUCInStackFrame to be able to extend call objects of arbitrary functions: js/src/jit-test/tests/jaeger/bug563000/eif-call-newvar.js js/src/jit-test/tests/jaeger/bug563000/eif-getter-newvar.js js/src/jit-test/tests/jaeger/bug563000/eif-trap-newvar.js Implementing this in all cases requires retaining enough information to undo all the def/use analysis the bytecode compiler does, possibly re-instating scope objects that don't exist any more on closures' scope chains, and so on. This is impractical. We should, however, verify that JS_EvaluateUCInStackFrame can extend the global and extensible call objects --- that is, in cases where the bytecode compiler has given up on binding analysis already.
