Log Message
The typedArrayLength function in FTLLowerDFGToLLVM is dead code.
https://bugs.webkit.org/show_bug.cgi?id=147749
Patch by Keith Miller <keith_mil...@apple.com> on 2015-08-06
Reviewed by Filip Pizlo.
Removed dead code elimination. the TypedArray length is compiled in compileGetArrayLength()
thus no one calls this code.
* ftl/FTLLowerDFGToLLVM.cpp:
(JSC::FTL::DFG::LowerDFGToLLVM::typedArrayLength): Deleted.
