How do I create a function in llvm IR which returns a StringMap datastructure?

thanks,
Bhavani

I think the simplest way to answer these sorts of questions is to write 
such a function in C++, then use llvm-g++ to compile it, with -emit-llvm.

You can disassemble the bitcode and see how to create one, or you can 
use llc -march=cpp to turn the bitcode into the C++ code that creates 
the equivalent bitcode.

Hope that helps,

Hi,

I need to use Value Numbering in my optimization pass. I dont see this being
used by any other passes. Please let me know which passes to include in
addRequired and how to getAnalysis for value numbering. addRequired<GVN>
doesn't seem to work.
Any help is appreciated!
    
Thanks in advance!
Bhavani
