Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-MacBook-Pro (MacBookPro11,3). VMs tested: "Conf#1" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r182860) "Conf#2" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r182860) 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 forgot to remove the destroy() functions in JSCallee/JSFunction/JSBoundFunction (should be dead code now). I am preparing an updated patch.

The bench results should still be valid for the new patch, but I will rerun them tomorrow to double check.

Comment on attachment 250889 [details] Fixed patch View in context: https://bugs.webkit.org/attachment.cgi?id=250889&action=review LGTM other than maybe using one too many GPRs. When you're ready to request review and have the reviewed patch committed, please set the review bit to "?" and the commit-queue bit to "?" as well. Then whoever reviews this can set both bits to "+" which will trigger the automatic commit bot. Our usual procedure for posting patches is: - Create a bug and upload a patch as you have done. - Post performance results as you have done, if applicable (some patches can safely be presumed to be perf-neutral). - Mark the patch r?/cq?. - Add appropriate reviewers to the CC on the bug. That would be me, ggaren@apple.com, and msaboff@apple.com. Maybe others. - Send e-mail to the reviewers to poke them. > Source/JavaScriptCore/dfg/DFGSpeculativeJIT32_64.cpp:3490 > + GPRTemporary rareData(this); See below... > Source/JavaScriptCore/dfg/DFGSpeculativeJIT64.cpp:3561 > + GPRTemporary rareData(this); Note that this increases the GPR usage of this code snippet, which then evicts other things from registers in case of pressure. It might be nice to avoid using a separate GPR for this... > Source/JavaScriptCore/dfg/DFGSpeculativeJIT64.cpp:3579 > - > - m_jit.loadPtr(JITCompiler::Address(calleeGPR, JSFunction::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfAllocator()), allocatorGPR); > - m_jit.loadPtr(JITCompiler::Address(calleeGPR, JSFunction::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfStructure()), structureGPR); > - slowPath.append(m_jit.branchTestPtr(MacroAssembler::Zero, allocatorGPR)); > + > + m_jit.loadPtr(JITCompiler::Address(calleeGPR, JSFunction::offsetOfRareData()), rareDataGPR); > + slowPath.append(m_jit.branchTestPtr(MacroAssembler::Zero, rareDataGPR)); > + m_jit.loadPtr(JITCompiler::Address(rareDataGPR, FunctionRareData::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfAllocator()), allocatorGPR); > + m_jit.loadPtr(JITCompiler::Address(rareDataGPR, FunctionRareData::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfStructure()), structureGPR); Is it clear that you need a separate GPR for rareDataGPR? Could you instead use structureGPR? I believe that this code would work fine: m_jit.loadPtr(JITCompiler::Address(calleeGPR, JSFunction::offsetOfRareData()), structureGPR); slowPath.append(m_jit.branchTestPtr(MacroAssembler::Zero, structureGPR)); m_jit.loadPtr(JITCompiler::Address(structureGPR, FunctionRareData::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfAllocator()), allocatorGPR); m_jit.loadPtr(JITCompiler::Address(structureGPR, FunctionRareData::offsetOfAllocationProfile() + ObjectAllocationProfile::offsetOfStructure()), structureGPR); This works because we only need the rareData until we load the structure, and it's OK to issue a load instruction that uses/defs the same register. Such a sequence would be strictly better from a register pressure perspective.

Created attachment 250927 [details] Remove additional GPR
Basile Clement
Comment 8 2015-04-16 10:25:39 PDT
Here is the new benchmark w/ the additional GPR removed. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Basiles-MacBook-Pro (MacBookPro11,3). VMs tested: "Conf#1" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r182874) "Conf#2" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r182874) 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.

No, that was a mistake (missed keystroke when saving), I updated the patch. Didn't know about the --32-bit though, I will run that.

[build/include_order] [4] We like to sort our #include's. Sometimes editing existing code reveals past style problems - even if it's a preexisting problem, we usually fix it if style bot complains. > ERROR: Source/JavaScriptCore/runtime/JSFunction.h:137: The parameter name > "exec" adds no information, so it should be removed. Yeah, just remove the name. > [readability/parameter_name] [5] > ERROR: Source/JavaScriptCore/runtime/JSCallee.h:29: Alphabetical sorting > problem.
