Reported 2015-09-13 12:34:08 PDT

The performance of LLInt get/put inline caches probably has little to do with whether the direct/indirect, inline/out-of-line, transition/replace distinctions are made using different opcodes or branches within a single opcode's implementation. So, we should simplify the code to use a single get_by_id opcode and a single put_by_id opcode. Also, the inline caches should use StructureID's as much as possible. Currently they use Structure*'s waaaay too much.

Performance is neutral. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on shakezilla (MacBookPro11,3). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r189679) "LLIntIC" at /Volumes/Data/quartary/OpenSource/WebKitBuild/Release/jsc (r189679) 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.
