Hi,

I'm currently trying to translate LLVM IR language to VPO .dec file specification. I'm using LLVM source parser in the same way that it is used in tools llc or llvm-as. One issue I'm having is I cannot find any static values. For example, in a global declaration i.e. '@a = global i32 7, align 4' I cannot get '7' from the parsed structure.

llvm::GlobalVariable::getInitializer()?

Similarly (sort of), once I'm looking at a parsed Function, and I go into a BasicBlock, and get say and add Instruction, and I get its operands, I can't get static values. If for example the Instruction was '%add = add i32 %tmp, 60', I can get the name of value 'tmp' which is enough, but I can't get the value '60'.

60 is an llvm::ConstantInt.

If you're still having trouble, feel free to ask more questions.
