[LLVMdev] Error while creating ExecutionEngine
Thanks Bill! But it does not work. I get the error given below when I try to load LLVMExecutionEngine.o in the opt command.
Error opening '../../../build/Release/lib/LLVMExecutionEngine.o': ../../../build/Release/lib/LLVMExecutionEngine.o: only ET_DYN and ET_EXEC can be loaded
-load request ignored.
Any ideas?? Please help me out here.
Thanks,
Bhavani

[LLVMdev] Is it possible to use EE within optimization pass?
I realize my questions may not have been so clear. To give more details. I am writing a fuction pass. I want to interpret some of the instructions within the function pass. In order to do so, I need to create an EE object within the function pass. Now, If I compile and execute using opt. I get an error(Error loading symbol) at the line where I am creating EE.

[LLVMdev] Is it possible to use EE within optimization pass?
Thanks John! My pass is registered only in 1 cpp file. It registers and executes fine without the EE.
I only get the Pass registered multiple times error when I try to link to the EE by using LINK_COMPONENTS=engine in the Makefile. Without that line in the Makefile, my pass gets registered fine but it is not able to create EE(Error reading Symbol). So, how do I link LLVMExecutionEngine.o without

Hi all,
I am repeating my question from yesterday coz I need to find a solution to this ASAP.
How do I link the executionengine to an optimization pass. If I use LINK_COMPONENTS=engine in the Makefile, I get the Pass registered multiple times error. And if i dont use anything, it is not able to load the EE. It gives error loading symbol error. So,

[LLVMdev] Assertion `InReg && "Value not in map!"' failed
Thanks Nick! ok. I ran through the verifier and this is the issue:
verifying... Instruction does not dominate all uses!
%tmp3 = add i32 %b, %a ; <i32> [#uses=2]
store i32 %tmp3, i32* %0, align 4
Broken module found, compilation aborted!
add is existing instruction in function. store is the instruction I have added to the function. How do I fix this now :(?
Thanks,

[LLVMdev] How do I get the result of an instruction?
Thanks!
How do I cast the result to a string? I basically need to store the results of some instructions in a file.
Thanks,

[LLVMdev] How do I get the result of an instruction?
Hi all,
I probably have a stupid question but I could not find out so please help me out here. I can use getOperand to get the operands of an instruction. Similarly, How do I get the result of an instruction?

[LLVMdev] Assertion `InReg && "Value not in map!"' failed
Ah! I get it now. Thanks a lot !
I changed it to BitCastInst(AI,VoidPtrTy,"",j);
And now I am getting the following error :(. I have been stuck with this error before also. I know I am missing out something silly. What is the cause of this error and Please let me know how to fix it.

[LLVMdev] Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"' failed.
ok.. So I am trying out what you have suggested. I have written the below code which basically tries to write the constant 10 to a file. myprint is a function pointer to a function which takes char * parameter and writes it to file.
Value *Ten = ConstantInt::get(Type::Int32Ty, 10);
const Type *VoidPtrTy = PointerType::getUnqual(Type::Int8Ty);
AllocaInst *AI = new AllocaInst(Type::Int32Ty);

The instruction itself is its result.
For example, if I wanted to generate code that does a getlemeneptr

[LLVMdev] How do I get the result of an instruction?
ok. I think I get it now. I need to create the instructions as you have given. For eg: I could pass Instruction*(for storing the result of this instruction) while creating the store instruction. This is what you meant rite??
Thanks,

[LLVMdev] Question in LLVM IR
Hi all,
I observed the nature of the LLVM IR and because of the SSA form, it does not preserve function local variable names (like it preserves function argument names). Is there any way to track these local variables?
Basically what I am doing is interpreting the IR against an abstract machien where I need to store the value of each program variable at any instance. Here I would get values for

If you're confused about how the IR works, http://llvm.org/demo/ can
be useful. The question you're asking doesn't really seem to make
sense.

[LLVMdev] How do I get the result of an instruction?
Hi,
I am writing an optimization pass where I need to instrument the code such that I need to store the results of some instructions in file. Using llc -march=cpp option I figured out how to add a function(say writeToFile) which takes char* parameter and writes to file. Now, I need put in a CallInst which calls writeToFile passing the Instruction result as parameter. How do I do this?
So, in my
