Reported 2015-08-20 21:30:09 PDT
After introducing byId ICs into byVal ops, byVal ops creates much ICs than before. https://bugs.webkit.org/show_bug.cgi?id=148273 The failure figures out these ICs are created even if this op is executed only once. The situation is the following; In the current code, when byVal op is executed with the Id, we immediately set up the byId IC for that byVal op. But setting up JITGetByIdGenerator generates the fast path IC code and consumes executable memory. As a result, if we call eval("contains byVal ops") with the different strings repeatedly under no-llint environment, each eval call creates byId IC for byVal and consumes executable memory. To solve it, we will add "seen" flag to ByValInfo. And we will create the IC on the second byVal op call with the same Id. The rough design is the following, if (!byValInfo->seen) { byValInfo->seen = true; byValInfo->cachedId = givenId; } else if (byValInfo->cachedId == givenId) Generate IC! else Make the call site generic.

Benchmark results. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, and JSRegress on Yusukes-MacBook-Pro (MacBookPro11,3). VMs tested: "master" at /Users/yusukesuzuki/development/WebKit/WebKitBuild/master-for-ic-fix/Release/jsc "ic" at /Users/yusukesuzuki/development/WebKit/WebKitBuild/ic-fix/Release/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.
