[cfe-dev] C++ to Python Project Proposal

[Jeff Kunkel]

I think I found it. Under "ModuleBuilder.h" in the codegen section there is
the 'class CodeGenerator' which inherits from ASTConsumer. Since, I do not
want to interface with 'CreateLLVMCodeGen' I do not want to use the
'CodeGenerator' class. However, I should be able to generate off of the
'ASTConsumer.'

Thanks,
Jeff Kunkel
