similar to: result of load Instruction

I'm writing a pass that eliminates some variables. To show the effect of the pass i need to show that I deleted the variables that originally appear in the user code, not temporary variables added by llvm.

Hi, I need to check if a variable belongs to the program originally. Consider the following code line: y = x + 4 and its corresponding llvm ir (roughly): %16 = load i32 %x %add = add i32 %16, i32 4 store i32 %add, %y I need to distinguish between %16, %add and %x, %y. Any help is appreciated. Best, Mohammad -------------- next part -------------- An HTML attachment was scrubbed... URL:

Sorry i'm using the following code: F = (cast<CallInst>(BI))->getCalledFunction(); for (auto& A : F->getArgumentList()) { errs() << "------- " << A.getName() << " " << "11" << "\n"; } But how can I get the parameters (as e and f in the example)? Thank you and best, Mo On

Hi, Do address spaces in llvm corespond to different memory locations? For example, Shared and Global refer to RAM while Local refers to registers? I guess that this may be true in GPU programming. So, I would like to know about CPUs. Thanks. Best, Mohammad -------------- next part -------------- An HTML attachment was scrubbed... URL:

Thanks David for your reply! However, OK is called inside nqueens. So, the same stack space cannot be used/reused for both of them.

what about the memory address of e and f? can i get them?

I tried the original posted code again: for (auto& A : cast<CallInst>(BI)->arg_operands()) errs() << "--- " << A->getName() << "\n"; but it prints empty (only ---)!

Hi, Is it possible to get debug information after optimization? for example, source code line numbers of instructions in an ir that is optimized by O2?

Hi Everyone, Does anyone know to get function parameters? For example, I want to get e and f in the call to function foo in the following code: foo(inr a , int b){ .... } main() { int e,f; e=10; f=22; *foo(e,f);* } I use the following code: for (auto& A : (cast<CallInst>(BI))->arg_operands ()) errs() << A.dump(); but I get a and b instead. Thank you

Hi, Could anyone please help me understand why Clang reallocates the same memory address for different variables while their lifetime intersect? Here is an example code: #include <stdlib.h> #include <stdio.h> #include <memory.h> #include <alloca.h> /* Checking information */ static int solutions[] = { 1, 0, 0, 2, 10, /* 5 */

Hello everyone, Can you please tell me if it is possible in LLVM to cast a `Value*` to an `Instruction*/LoadInst*` if for example `isa<LoadInst>(MyValue)` is true? In my particular piece of code: Value* V1 = icmpInstrArray[i]->getOperand(0); Value* V2 = icmpInstrArray[i]->getOperand(1); if (isa<LoadInst>(V1) || isa<LoadInst>(V2)){ ...

Hi, I was trying to create a new *Store* instruction and inserting it to LLVM IR (.ll) file. I found the following constructor in LLVM Manual: StoreInst::StoreInst <http://llvm.org/docs/doxygen/html/classllvm_1_1StoreInst.html#aa2a72f9a51b317f5b4ab8695adf59025> (Value <http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html> * Val, Value

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? Thanks, Bhavani

Most LLVM IR instructions have a result field, according to the Language Reference. I want to know, for all LLVM Instructions, is there an easy and consistent way to know if the current Inst has a result field? And if yes, what is the best way to obtain it? E.g.: <result> = add<ty> <op1>,<op2> /; yields {ty}:result / All ADD instruction will have a

Folks, I have a LLVM instruction like the following %0 = load i32** %pp, align 8 I have a LoadInst &inst handle to this instruction. In addition, i could access the pointer being loaded from using the inst.getPointerOperand... However, is there a way to access the handle to the value being loaded? Essentially, i wanted to access the %0 in the statement listed. The end goal is
