::I choose “Improveing JIT compiling” project, focusing on “Enhance JITC functionality” and “Migrate from LLVM JIT to LLVM MCJIT”. Current JITC lacks some feature. In addition disablility of built-in function linking, JITC cannot work with matrices data type but only scalar type. I want to concentrate on expanding JITC to handle this non-trivial but fundamental case.  
::I choose “Improveing JIT compiling” project, focusing on “Enhance JITC functionality” and “Migrate from LLVM JIT to LLVM MCJIT”. Current JITC lacks some feature: Functions and exponents (e.g. 2^z) cannot compile with the JITC. I want to concentrate on expanding JITC to handle this non-trivial but fundamental case.  
::Second, I would begin to migrate from LLVM JIT to LLVM MCJIT. JITC use JIT now, however LLVM community has no longer maintain JIT and move on MCJIT. I think we could move on MCJIT (and still support JIT). This is really important if we want to get the benefit from LLVM subsequently.

::When all essential case has been added, I would try to implement some JIT related optimization into JITC (like trace/method-based JIT).

:During GSoC period. I would focus on "Enhance JITC functionality". "Migrate from LLVM JIT to LLVM MCJIT" would be completed in free time.
