Ran benchmarks because of changing create_this It's claiming a big slow down on json-stringify-tinderbox, but I don't trust that it's actually a slow down. I haven't changed code related to that benchmark and have seen a slow down (like now), and I've also changed code not related to it and seen a speed up in the past. I'm going to ignore it for now. When running just that benchmark without the entire suite, I was getting about a 4% "slowdown". Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Saams-MacBook-Pro (MacBookPro11,3). VMs tested: "og" at /Volumes/Data/WK/a/OpenSource/WebKitBuild/Release/jsc (r196836) "change" at /Volumes/Data/WK/c/OpenSource/WebKitBuild/Release/jsc (r196836) 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. og change SunSpider: 3d-cube 7.3352+-0.4663 7.1460+-0.1870 might be 1.0265x faster 3d-morph 8.1139+-0.1181 8.0964+-0.1144 3d-raytrace 9.6134+-2.8296 9.1818+-0.9997 might be 1.0470x faster access-binary-trees 3.0880+-0.0443 3.0793+-0.0598 access-fannkuch 9.0050+-0.1508 8.8686+-0.2245 might be 1.0154x faster access-nbody 4.0245+-0.2063 3.9428+-0.0500 might be 1.0207x faster access-nsieve 4.9777+-0.2602 4.9047+-0.0782 might be 1.0149x faster bitops-3bit-bits-in-byte 1.6918+-0.0608 ?

We have two conflicting definitions, so the cast is necessary. I'm not sure that the API is dangerous, because you will get a compiler error without the cast. That said, I think we could make it cleaner. It would be super easy to do, we can just name the one I'm calling in this patch something like: constructArrayWithAllocationProfile(...) The conflicting definitions are: inline JSArray* constructArray(ExecState* exec, ArrayAllocationProfile* profile, const ArgList& values, JSValue newTarget = JSValue()) // in JSGlobalObject.h inline JSArray* constructArray(ExecState* exec, Structure* arrayStructure, const ArgList& values) // in JSArray.h
