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.

Thanks again for your reply. You are right. But i am looking to change the value of that constant value and use that as operand in other 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.

...plement 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.

Hi, I am new to xen internals. I want to understand, what events are generated for sending/receiving network packet of guest domains in xen and preferably to generate their logs. Any help, where and how to start? Thanks, Krishna _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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

Thanks for the quick reply. I am able to get the numerical value. But i also need the numerical value to be in value type, so that it can be used as operand of other instruction. For that i am trying to create a new ConstantInt, but i am unable to find create() function for ConstantInt. Thanks again for the quick and helpful reply.

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.

Hello, how to get the numerical value of an constant operand? For ex. %tmp = mul i32 %indvar, 6 , in 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.

Thanks for reply. I have used AllocaInst, it's working but i think it's only for allocating some memory for new variable. And CallInst creates a call instruction. I am looking for creating a add or sub instruction. I used function instruction(), which gives me error "error: cannot allocate an object of abstract type ‘llvm::Instruction’" and also "Instruction.h:28: note:
