Bug 141332

Created attachment 246166 [details] work in progress

Created attachment 246212 [details] slowly coming along

Created attachment 246226 [details] more things

Created attachment 246344 [details] even more

Created attachment 246349 [details] DFG 64-bit CallVarargs done Still a lot more to do, but it's coming along.

Created attachment 246351 [details] DFG LoadVarargs 64-bit done Now I need to write the FTL side.

Created attachment 246417 [details] OMG so much code I wrote most of the meat of the FTL varargs call, and filled in some missing junk for the inline call frame arguments register.

Created attachment 246418 [details] more Closing the loop on call varargs in the FTL

Created attachment 246423 [details] 64-bit might be done I haven't even tried compiling yet.

Created attachment 246451 [details] starting to compile, and reworking CallForwardVarargs in FTL

Created attachment 246542 [details] almost compiling

Created attachment 246549 [details] it compiles!

Created attachment 246561 [details] it passes some of our tests! Fails about 55 of them. Still debugging...

Created attachment 246585 [details] now passes more tests than ever!

Created attachment 246598 [details] it's passing so many tests I still need to write my own tests for this, however. For example, ConstructVarargs never hits FTL in any of our current tests. Currently the only tests that fail are regress/script-tests/call-spread-apply.js and regress/script-tests/call-spread-call.js. Everything else passes.

Created attachment 246629 [details] almost passing all tests The latest crash I'm working on is because GetArgument with Int32 flush type tries to speculate, which isn't what we want. This should fix it: https://bugs.webkit.org/show_bug.cgi?id=141623

Created attachment 246669 [details] more FTL fixes

Created attachment 246676 [details] more fixes, more tests

Created attachment 246706 [details] 64-bit tests pass Still have to implement the 32-bit DFG portion.

The perf results are intriguing. On the major benchmarks, the results are great. But JSRegress is showing signs of trouble - several tests with >2x slow-downs. I'll investigate. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/jsc (r180189) "Varargs" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r180189) 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.

I figured out the performance regressions: I broke typed array constructor inlining, and this appears to only have mattered on our microbenchmarks. I broke it accidentally as part of the refactoring I had to do in the inlining code.

OK, all performance is good now. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/jsc (r180189) "Varargs" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r180189) 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.

I tested the latest patch and it doesn't build on ARMv7 Linux. Could you possibly give us a little bit time (max a day) to fix before landing?

(In reply to comment #28) > I tested the latest patch and it doesn't build on ARMv7 Linux. Could you > possibly give us a little bit time (max a day) to fix before landing? At least helpers are missing from Source/JavaScriptCore/jit/CCallHelpers.h, I don't know if there is any issue later, but I'm on it.

I fixed the ARM Linux build in bug141714, please review and land it before landing this patch. Thanks. Additionally I started JSC tests, it is still running, but no regression at 10% .

(In reply to comment #28) > I tested the latest patch and it doesn't build on ARMv7 Linux. Could you > possibly give us a little bit time (max a day) to fix before landing? In the past, the way we worked this out was that I CC'd you on the bug before landing and then you would fix after. Are you proposing a change to this?

Nope, I thought it is a bigger change, but I already fixed it. ;)

I noticed it wasn't ARM Linux specific build issue, it was exactly same as the iOS EWS noticed.

Created attachment 246757 [details] closer to landing Fixed some debug asserts and crashes. Still need to deal with some ARMs.
