Basile Clement
Reported 2015-04-21 15:07:38 PDT
Created attachment 251267 [details] First patch Currently, only object allocations are sunk by the DFG allocation sinking phase. This adds the ability to sink function allocations as well, test cases forthcoming.

Created attachment 251511 [details] Updated patch Hopefully correct; still needs more testing. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-MacBook-Pro (MacBookPro11,3). VMs tested: "Trunk" at /Volumes/Data/Baseline/OpenSource/WebKitBuild/Release/jsc "SinkNewFunction" at /Volumes/Data/WIP/OpenSource/WebKitBuild/SinkNewFunction/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.

I followed the style of other lambdas on that one ; should I fix it?

It's a bug in stylebot. It doesn't parse lambdas correctly, yet. We ignore these errors for lambdas.
