REGRESSION (r190289): Repro crash clicking back button on netflix.com https://bugs.webkit.org/show_bug.cgi?id=150220 Reviewed by Geoffrey Garen. Source/JavaScriptCore: Since constructors check for a valid new "this" object and return it, we can't make a tail call to another function from within a constructor. Re-enabled the tail calls and the related tail call tests. Did some other miscellaneous clean up in the tail call code as part of the debugging. * bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::BytecodeGenerator): * ftl/FTLLowerDFGToLLVM.cpp: (JSC::FTL::DFG::LowerDFGToLLVM::callPreflight): * interpreter/Interpreter.h: (JSC::calleeFrameForVarargs): * runtime/Options.h: * tests/es6.yaml: * tests/stress/dfg-tail-calls.js: (nonInlinedTailCall.callee): * tests/stress/mutual-tail-call-no-stack-overflow.js: (shouldThrow): * tests/stress/tail-call-in-inline-cache.js: (tail): * tests/stress/tail-call-no-stack-overflow.js: (shouldThrow): * tests/stress/tail-call-recognize.js: (callerMustBeRun): * tests/stress/tail-call-varargs-no-stack-overflow.js: (shouldThrow): LayoutTests: Added a new regression test. Changed the expected output of caller-property to correspond with tail calls enabled. * js/caller-property-expected.txt: * js/regress-150220-expected.tx: Added. * js/regress-150220.html: Added. * js/script-tests/regress-150220.js: Added.
