Summary Crash in JSC::FTL::LowerDFGToLLVM::compileCompareStrictEq
Vanessa Freudenberg
Reported 2014-12-08 07:29:15 PST
Safari (and WebKit nightly) crashes reproducibly after a couple of seconds running this (which works fine in Chrome and Firefox): http://bertfreudenberg.github.io/SqueakJS/etoys/ It's not trivial to isolate the problem. This is a full Smalltalk Virtual Machine with its own JIT and memory management, but if I can be of any help: I am the main developer.

I could reproduce with Safari 8 (didn't try nightlies or trunk).

Here is the source for the function that is being compiled: function tallyIntoMapwith(sourceWord, destinationWord) { var pixMask; var mapIndex; var destShifted; var i; var maskShifted; var pixVal; if ((cmFlags & (ColorMapPresent | ColorMapIndexedPart)) !== (ColorMapPresent | ColorMapIndexedPart)) { return destinationWord; } pixMask = maskTable[destDepth]; destShifted = destinationWord; maskShifted = destMask; for (i = 1; i <= destPPW; i++) { if ((maskShifted & pixMask) !== 0) { /* Only tally pixels within the destination rectangle */ pixVal = destShifted & pixMask; if (destDepth < 16) { mapIndex = pixVal; } else { // Crashes checking the IR generated for the next statement if (destDepth === 16) { mapIndex = rgbMapfromto(pixVal, 5, cmBitsPerColor); } else { mapIndex = rgbMapfromto(pixVal, 8, cmBitsPerColor); } } tallyMapAtput(mapIndex, tallyMapAt(mapIndex) + 1); } maskShifted = SHR(maskShifted, destDepth); destShifted = SHR(destShifted, destDepth); } return destinationWord; }

Tested performance with of adding the a FTL::canCompile() check to validate that the DFG graph is suitable for lowering to LLVM and got a huge slowdown. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on msaboff-pro (MacPro5,1). VMs tested: "Baseline" at /Volumes/Data/src/webkit.baseline/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/jsc "CheckFTLCapabilitesAgain" at /Volumes/Data/src/webkit/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/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. Reporting benchmark execution times with 95% confidence intervals in milliseconds.

Seems like capabilities is rejecting some SSA-only node. Have you checked which one? The verboseFTLFailure option helps.

Created attachment 246339 [details] Patch for Review With the addition of GetArgument to nodes the FTL can compile, performance of this change is neutral. Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on msaboff-pro (MacPro5,1). VMs tested: "Baseline" at /Volumes/Data/src/webkit.baseline/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/jsc "GCDontDropLocks" at /Volumes/Data/src/webkit/WebKitBuild/Release/JavaScriptCore.framework/Versions/A/Resources/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. Reporting benchmark execution times with 95% confidence intervals in milliseconds.

I still see the linked application crash with Safari 8.0.4 on OS X Yosemite 10.10.2. Is it expected that this fixed is in Safari 8.0.4?
