EFL JSC tests fail due to performance regression. I'll investigate it.

Comment 7 2015-05-26 12:35:44 PDT
Ah, OK. This test is flaky (I think this patch is not related to it). (this patch's build is https://build.webkit.org/builders/EFL%20Linux%20ARMv7%20Thumb2%20Release/builds/13243) Before this patch, it is failed frequently. https://build.webkit.org/builders/EFL%20Linux%20ARMv7%20Thumb2%20Release/builds/13238 https://build.webkit.org/builders/EFL%20Linux%20ARMv7%20Thumb2%20Release/builds/13234

This change may have caused a ~1% Octane regression according to our bots (there are several commits in the range but this seems the most likely).

Investigating into it. Too frequent `parseIndex` seems related I think now.

I'll submit the patch and performance result.

Octane benchmark results. Core i7, Linux Ubuntu 14.04, gcc 4.9, GTK port. Baseline: The old revision, r184858, it doesn't include this patch. Patched: The trunk + proposed patch Trunk: the tip of trunk r184882 Hmm, maybe, this micro-optimization avoid some `parseIndex` calls. But the benchmark results show that there's not so regression... Benchmark report for Octane on gpgpu. VMs tested: "Baseline" at /home/yusuke/dev/WebKit/WebKitBuild/older/Release/bin/jsc "Patched" at /home/yusuke/dev/WebKit/WebKitBuild/property-name/Release/bin/jsc "Trunk" at /home/yusuke/dev/WebKit/WebKitBuild/Release/bin/jsc 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.
