QUERY regarding IR(Intermediate representation)

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

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.)
