149931 – DFG SSA should remove unreachable code

Filip Pizlo

Reported 2015-10-08 13:12:36 PDT

We already sometimes remove unreachable code, but in case AI proves that some code is unreachable, we sort of keep it around. This is mostly OK because everyone sort of knows that it's unreachable. But it would be easier for the compiler if it was removed entirely.

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 (r190682) "KillStuff" at /Volumes/Data/quinary/OpenSource/WebKitBuild/Release/jsc (r190682) 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.
