Created attachment 264440 [details] WIP Almost done. I want to write a few more tests, clean up a bit of code, rebase the patch, and then I think this is done. Tests I still want: - exception thrown from inline cache miss (i.e, from operationGetByIdOptimize) - exception from lazy slow path - exception thrown and caught in correct inline frame.

Add one more thing to do: - Make the list of things we spill from a JSCall a number based on live values in the catch and not all volatile registers

Note that run-jsc-benchmarks isn't smart enough to clear environment between runs, so this will see JSC_useFTLTryCatch=1 for some subset of runs. You can avoid this by explicitly giving it JSC_useFTLTryCatch=0. > "tryCatchFTL" at /Volumes/Data/WK/os-b/OpenSource/WebKitBuild/Release/jsc > (r191931) > export JSC_useFTLTryCatch=1 > > Collected 8 samples per benchmark/VM, with 8 VM invocations per benchmark. > Emitted a call to gc() between sample measurements. > Used 1 benchmark iteration per VM invocation for warm-up.

I'll investigate the code load regression. Maybe it's the same thing that sun spider is telling us.

Comment 13 2015-11-09 22:16:37 PST
Performance looks better. I've sped up the check to see if some code origin is inside a try block and I think that's likely the cause for things that looked like compilation slow downs. I'll land this patch tonight or tomorrow. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on Saams-Mac-Pro (MacPro6,1).
