[LLVMdev] Qualitative comparisons between Open64 and llvm
...http://www.pathscale.com/node/18 .
4,Open64 has a maillist, you can get more help there.

5. Compare to LLVM and GCC, Open64's document is less. But code is
the best way, and the comment gives many information. : )
6, while for retarget, Open64 use a targ_info directory for machine
description, such as instruction, register, and scheduling
information. While for multi core processors, Open64 already have
openmp support.
While for LLVM, I think other guys in this maillist can give you much
more information : )

[LLVMdev] Qualitative comparisons between Open64 and llvm
Hi,
I have been working towards developing compiler optimization tools
targeting multi core processors while using LLVM IR as the starting
point and building on top of the analysis and optimization passes
available in the llvm source.
Recently, I looked into Open64 and its intermediate representation
WHIRL. Documentation for developers to use Open64 seems to be inadequate
(when compared to LLVM
