Hello

I have a pointer to llvm::Value *,I know its a pointer to some llvm::CompositeType (vector)
Could you please tell me how can I get a value of specific index in the vector.
Thank you.

Use the extractelement instruction, like so:

   Value *Elem = Builder.CreateExtractElement(MyVectorValue, ElementNumber);

See http://llvm.org/docs/LangRef.html#i_extractelement .
