Allow sinking of NewArray and NewArrayBuffer
Created attachment 254197 [details] Patch
Benchmark looks good, except Kraken/audio-dft that seems to regress for some reason. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-Mac-Pro (MacPro6,1). VMs tested: "r185155" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc "SinkNewArray" at /Volumes/Data/secondary/OpenSource/WebKitBuild/SinkNewArray/Release/jsc 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. r185155 SinkNewArray SunSpider: 3d-cube 6.8622+-0.1667 6.8225+-0.0636 3d-morph 7.5643+-0.0574 ? 7.6480+-0.2879 ? might be 1.0111x slower 3d-raytrace 8.4341+-0.0780 ?

I stand by my first observation, I can't make sense of this, and 10% is a lot. Seemingly irrelevant small code changes move it from 10% to 2%.

I will change the tests to check the length of the underlying array then.

There’s another thing to remember about the function isUInt32 in cases like this. To quote a comment that appears in three places in the source code: "Despite its name, JSValue::isUInt32 will return true only for positive boxed int32_t". So it will return false for pow(2, 30) and higher. Maybe we should rename that function.

Looks reasonable. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-MacBook-Pro (MacBookPro11,3). VMs tested: "ToT" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc "SinkNewArray" at /Volumes/Data/secondary/OpenSource/WebKitBuild/SinkNewArray/Release/jsc 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.
