Thanks Duncan, Yes, it is a ConstantExpr! Thank you! Now trying to find a clue in ConstantExpr's functions to get that string :-) Regards, Welson On Thu, Jan 26, 2012 at 9:04 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi Welson Sun, > > > Hi, if I have some LLVM code like this: > > > > @.str = private unnamed_addr constant [7 x i8]

Hello, i parse the llvm IR (llvm-3.3 version) and when i meet a constant, i want to get it's value. eg i32 5, i want to get the 5. I am interested in ConstantInt-ConstantFP-ConstantArray-ConstantStruct subclasses. Things are a bit easier with ConstantInt and ConstantFP constants but how could i get the value of a ConstantArray? The

...;t it an implementation aspect? I mean, you can have a metadata nodes which members are pointers; if two nodes have to share the same member instance, they can share the same pointer. After all, even when two instructions refer to a structurally equivalent Constant object (https://llvm.org/doxygen/classllvm_1_1Constant.html#details), they actually share the same pointer to the same Constant object. > Pre-RA it's relatively easy as long as we're still in SSA.
