Seems performance neutral. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Geoffrey-Garens-Mac-Pro (MacPro6,1). VMs tested: "Base" at /Volumes/Big/ggaren/OpenSource/WebKitBuild/Release/jsc (r189584) "Patch" at /Volumes/Big/ggaren/OpenSource/WebKitBuildPatch/Release/jsc Collected 4 samples per benchmark/VM, with 4 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.
