Bug 143735

Created attachment 251135 [details] work in progress Currently this crashes instantly. :-)

Created attachment 251274 [details] it works but it might be slow Still checking performance and such.

Created attachment 251292 [details] probably fast enough Still doing more tests though.

Created attachment 251396 [details] more speed

Latest perf numbers: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/jsc (r183094) "Phantoms" at /Volumes/Data/pizlo/quartary/OpenSource/WebKitBuild/Release/jsc (r183094) 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.

The comment above says: /* Note that GetLocal is MustGenerate because it's our only way of knowing that some other */\ /* basic block might have read a local variable in bytecode. We only remove GetLocals if it */\ /* is redundant because of an earlier GetLocal or SetLocal in the same block. We could make */\ /* these not MustGenerate and use a more sophisticated analysis to insert PhantomLocals in */\ /* the same way that we insert Phantoms. https://bugs.webkit.org/show_bug.cgi?id=144086 */\ It's the non-local equivalent of making MovHint a strong use, sort of. The associated bug that this references would be the more elegant solution, which I'll do in some future patch.
