It looks like this was the cause of the ~1% regression on Kraken. The revert put us back to the original speed.

According to rniwa, this is what went wrong: https://build.webkit.org/builders/Apple%20Yosemite%20Debug%20JSC%20%28Tests%29?numbuilds=25 It looks like there's a new JSC crash introduced in the last 12 hours or so: ** The following JSC stress test failures have been introduced: stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate stress/load-varargs-then-inlined-call-inlined.js.ftl-no-cjit-validate stress/load-varargs-then-inlined-call.js.ftl-no-cjit-validate The stack trace looks like this: Running stress/load-varargs-then-inlined-call.js.ftl-eager stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: ASSERTION FAILED: canAccessIndexQuickly(i) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: /Volumes/Data/slave/yosemite-debug/build/Source/JavaScriptCore/runtime/DirectArguments.h(87) : void JSC::DirectArguments::setIndexQuickly(JSC::VM &, uint32_t, JSC::JSValue) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 1 0x10f8d9e50 WTFCrashWithSecurityImplication stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 2 0x10f1d83d6 JSC::DirectArguments::setIndexQuickly(JSC::VM&, unsigned int, JSC::JSValue) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 3 0x10f7a0abc operationMaterializeObjectInOSR stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 4 0x39f8020104de stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 5 0x39f80200b6e1 stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 6 0x10f675c79 vmEntryToJavaScript stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 7 0x10f4db9fc JSC::JITCode::execute(JSC::VM*, JSC::ProtoCallFrame*) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 8 0x10f4bf57e JSC::Interpreter::execute(JSC::ProgramExecutable*, JSC::ExecState*, JSC::JSObject*) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 9 0x10efe7240 JSC::evaluate(JSC::ExecState*, JSC::SourceCode const&, JSC::JSValue, JSC::JSValue*) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 10 0x10ee568f4 runWithScripts(GlobalObject*, WTF::Vector<Script, 0ul, WTF::CrashOnOverflow, 16ul> const&, bool) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 11 0x10ee55eb6 jscmain(int, char**) stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 12 0x10ee559db main stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 13 0x7fff980755c9 start stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: 14 0x9 stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: test_script_10434: line 2: 55860 Segmentation fault: 11 "$@" ../../.vm/JavaScriptCore.framework/Resources/jsc --useFTLJIT\=false --enableFunctionDotArguments\=true --validateGraph\=true --useFTLJIT\=true --ftlCrashesIfCantInitializeLLVM\=true --enableConcurrentJIT\=false --thresholdForJITAfterWarmUp\=100 load-varargs-then-inlined-call-exit-in-foo.js stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate: ERROR: Unexpected exit code: 139 FAIL: stress/load-varargs-then-inlined-call-exit-in-foo.js.ftl-no-cjit-validate Running stress/load-varargs-then-inlined-call.js.ftl-eager-no-cjit

By the way, here's the performance of this. Note that I accidentally used "FastHole" to describe this patch during this benchmark run. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r184438) "FastHole" at /Volumes/Data/pizlo/primary/OpenSource/WebKitBuild/Release/jsc (r184438) Collected 6 samples per benchmark/VM, with 6 VM invocations per benchmark. Emitted a call to gc() between sample measurements. Used 1 benchmark iteration per VM invocation for warm-up. Used the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark execution times with 95% confidence intervals in milliseconds.
