Description Filip Pizlo 2011-07-06 13:07:53 PDT
The DFG speculative JIT may perform a speculation that turns out to be statically false. In this case, speculative code generation is rolled back. Despite the fact that this feature is already implemented, there is still a FIXME in DFGSpeculativeJIT.h that indicates that we should implement this already-implemented feature. Additionally, the same code path also generates a speculation check despite the fact that any code generated by this path will be rewound.
