If we do a comparative study between following IRs:


  A) WHIRL
  B) LLVM
  C) GIMPLE(gcc- tree)


Then please comment on the above IRs considering following points:




  1.Source Code Information (contain only
necessary source code information)


  2.Optional information for Optimization (Can be segregated from
source code information)


  3.Optimizations: (Easy for Optimizer to transform)


  4.Extendibility (Vendor specific features
such as compiler directives)


  5.Portability: (Should be capable to support wide
variety of hardware architecture.)
                                                                              For example (Vectorization
support)


  6.Convertibility: (Developing IL translators should be
of manageable complexity.)


  Thanks and Regards,
