There's an entire tutorial at http://llvm.org/docs/tutorial which includes covers the IRBuilder to generate all sorts of IR, including the add instruction. You can skip ahead to chapter 3 if you just want to see LLVM API, but I suggest you read the whole tutorial if you have the time.

...n this instruction second operand is a numerical constant with value 6. But i am only able to print it by using getOperand(1), not able to store it in any integer variable. Using getName() returns a empty string. Is there any way to solve this problem? Thank you.

...her instruction. For example there is one constant operand with value 6, i will multiply it with 2, and then use 12 as operand in other instruction. So i need to convert 12 to value class and then i will be able to set it as operand. Hope i am clear now. Thanks.

Can you please give an example of creating an instruction (for example add instructions with two operand a and b)? I am trying instruction() for a while, but no success yet.

Can anyone tell how to get the result name or instruction name of all instruction? For example if the instruction is "x=add y,z", here i need "x". Using getName(), i am getting some instructions result name, but llvm produces some instruction like "%0=add i32 tmp, 1", here getName() shows empty string as result name. So please help.

Can you tell how to use vector globally? I mean, i am able to add entries to a vector in a basicblock, but whenever a basicblock function call is returned, the vector becomes empty. So how to use data structures globally? And one thing, where is main ( or same kind of) function in llvm? Thanks for you reply. Duncan Sands wrote: > > Hi, > >> Actually i have to implement strength

Actually i have to implement strength reduction, for that i have to first detect induction variables using ALLEN-COCKE-KENNEDY algorithm. To find out induction variables, i need the name of the instruction. Thanks for the reply.
