Patch
Benchmark report for SunSpider, V8Spider, Octane, Kraken, JSBench, JSRegress, and DSP on bigmac (MacPro5,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/quartary/OpenSource/WebKitBuild/Release/DumpRenderTree (r146839) "FixPDFJS" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/DumpRenderTree (r146839) Collected 12 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.
