Hi All,
I have a query regarding IL design. Please suggest me, which IL to
choose or referred from the following three:


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


If i consider the following points for IL design:
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,
Manish Agarwal
