[LLVMdev] Internal compiler error in SelectionDAGBuild.cpp

[Bob Wilson]

Thanks for the bug report.  The attached file isn't helpful for  
reproducing the problem.  I don't have all the header files that are  
included, so I can't just try to run it through my version of llvm-gcc  
and see what happens.  At a minimum, please attach the preprocessed  
source file along with the complete llvm-gcc command line that you  
used to compile it.  That would probably be good enough, but since I  
don't have a copy of llvm-gcc configured for OMAP Linux, it would be  
much better if you could submit the LLVM bitcode file.  Have a look at  
the following doc on the LLVM website:

Thanks!
