...ing to a string name, and is only really important for clarity and debugging the IR being produced. It means you could start out with something like [...] %1 = add i32 %lhs, %rhs ret i32 %1 [...] (where the %1 is just an automatically incrementing label provided by LLVM) then call MyAddInst.setName("theSum") and LLVM would automatically convert this to: %theSum = add i32 %lhs, %rhs ret i32 %theSum You still have to have an initialised, valid Value pointer to be able to do this. > 3- I'm not sure about "select" instruction, you mean that the addres...

1- I need the first example. 2- I set the Address uninitialized according to the documentation " Setting the name on the Value automatically updates the module's symbol table" from Value.h source code 3- I'm not sure about "select" instruction, you mean that the address is the new destination (basic block)that will be added Thanks On 23 July 2013 16:38, Tim Northover
