At some point it starts printing 2.236.... (for sqrt of 5) which is the expected result, but shouldn't be printed since it's not a negative number. Furthermore, some iterations later it starts printing some large (negative for some inputs to sqrt) number. I noticed it breaks for some numbers inside sqrt (5,7,11,15) but not for others (6, 13) 785020 1 178028 ap 2012-12-06 10:33:18 -0800 Created attachment 178028 same test as an attachment 785022 2 ap 2012-12-06 10:34:15 -0800 Hits an assertion failure in debug ToT: ASSERTION FAILED: originalNode->shouldGenerate() /Users/ap/Safari/OpenSource/Source/JavaScriptCore/dfg/DFGCFGSimplificationPhase.cpp(309) : void JSC::DFG::CFGSimplificationPhase::fixPossibleGetLocal(JSC::DFG::BasicBlock *, JSC::DFG::Edge &, bool) 1 0x10d872563 JSC::DFG::CFGSimplificationPhase::fixPossibleGetLocal(JSC::DFG::BasicBlock*, JSC::DFG::Edge&, bool) 2 0x10d870fb0 JSC::DFG::CFGSimplificationPhase::mergeBlocks(unsigned int, unsigned int, unsigned int) 3 0x10d86fb9e JSC::DFG::CFGSimplificationPhase::run() 4 0x10d86f8c5 bool JSC::DFG::runAndLog<JSC::DFG::CFGSimplificationPhase>(JSC::DFG::CFGSimplificationPhase&) 5 0x10d86f855 bool JSC::DFG::runPhase<JSC::DFG::CFGSimplificationPhase>(JSC::DFG::Graph&) 6 0x10d86f768 JSC::DFG::performCFGSimplification(JSC::DFG::Graph&) 785023 3 ap 2012-12-06 10:34:28 -0800 <rdar://problem/12826880> 785194 4 fpizlo 2012-12-06 13:30:21 -0800 Fascinating! It looks like this is somehow exposing a bug in our CFG simplifier. That's why the irrelevant branch is so important - without it we don't do CFG simplification, and presumably, don't end up breaking the IR leading to bad codegen. 785455 5 178118 fpizlo 2012-12-06 17:28:22 -0800 Created attachment 178118 fix the assertion 785457 6 fpizlo 2012-12-06 17:28:56 -0800 (In reply to comment #5) > Created an attachment (id=178118) [details] > fix the assertion I'm still running layout tests.
