The refactoring of for in completed in http://trac.webkit.org/changeset/171605 with the addition of the FTL part in http://trac.webkit.org/changeset/171763 introduced three independent loops. If a property is added in a one loop, it can be enumerated in a subsequent loop. rdar://problem/19121373
Created attachment 249003 [details] LLInt and baseline JIT appear to work
Created attachment 249134 [details] Coding complete for all tiers. One failure in the FTL. More tests to write.
Created attachment 249299 [details] Patch Performance tests forthcoming.

I'll remove. I was toying with a couple of different ways to modify the enumerated object.
Only one notable slow down, string-fasta in the LongSpider harness. Richards and audio-beat-detection show nice speed ups. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on msaboff-pro (MacPro5,1). VMs tested: "Baseline" at /Volumes/Data/src/webkit.baseline/WebKitBuild/Release/jsc (r181869) "Patch142856" at /Volumes/Data/src/webkit/WebKitBuild/Release/jsc (r181869) 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.
