Dear All, I need your help urgently I have to copy the CFG of each function using CloneFunction or CloneFunctionInto. After I made the copy function. Print the basic blocks then get this error : While deleting: i32 % Use still stuck around after Def is destroyed: %mul2_ = mul nsw i32 %6, 3 Use still stuck around after Def is destroyed: store i32 3, i32* %x_, align 4 opt: Value.cpp:75: virtual

I was just going to say: With well-formed debug info it should create a deep copy up until the DISubprogram, but no further. But because the DISubprogram linked to the Function is missing the special handling of the DISubprogram (that would prohibit cloning the DICompileUnit is side-stepped). But then I remembered the discussion we had in

Does cloning copies the function with its address or it constructs a new address to the new function? Is this real copying for the CFG or just opaque one to do some work? If it's not real copying, please I need a method that can help me in copying the function in another with new pointer to another address. Please I need answer urgent Thanks On 29 May 2013 10:14, Rasha Omar <rasha.sala7

Hi Medhi, Thanks for you reply. Here is the full output of -print-after-all [1] and just the module itself after my pass[2]. I've looked over the IR, but I can't see anything obviously wrong. I'm not sure what you meant by: > You may want to try to add it at the end of the pipeline My pass is the last one added inside populateLTOPassManager. Should I add it to the

The if you are cloning into the same LLVM module the CU should not cloned. If don't mind sharing your code, I can try to help diagnose why the CU gets cloned... just send me a patch that applies to trunk and instructions. -- adrian > On Jun 16, 2017, at 1:54 PM, Sergei Larin <slarin at codeaurora.org> wrote: > > Sorry… It takes a pass that was not accepted for upstreaming….

Can you send me a patch with instructions to reproduce? I can take a look. -- adrian > On Jun 15, 2017, at 2:23 PM, Sergei Larin <slarin at codeaurora.org> wrote: > > Yes, it does for us.

Hi Philip, Thanks for the reference, I was able to follow it and copy the code that I saw necessary, but I still have some issues (references are still not updated). I created the function: void populateVMap(llvm::ValueToValueMapTy &VMap, llvm::Function *fOld, llvm::Function *fNew) { llvm::Function::arg_iterator DestI = fOld->arg_begin(); for (llvm::Function::const_arg_iterator J =

Hi Philip, The error happens when the program finishes and it automatically calls the destructors, so it is not an error specifically inside my program. Here's the full code: #include "llvm/ExecutionEngine/ExecutionEngine.h" #include "llvm/ExecutionEngine/MCJIT.h" #include "llvm/IRReader/IRReader.h" #include "llvm/Support/TargetSelect.h" #include

I'm trying to create a clone of a function using Function::Create() and CloneFunctionInto. However, I'm running into an issue. I believe that the instructions in the function clone still have Use edges to values in the original function. This is a problem for my purposes. For example, consider an original function F. I create a new function G belonging to the same module and call

Hi, supposing I have a function “foo” like the following: int foo(int a, int b) { ... ... } I want to insert int the LLVM IR a call instructions to a function “bar” that requires the same parameters of foo. So my function foo will become: int foo(int a, int b) { bar(a,b); … ... } I am using the following code: bool ThreadSanitizer::runOnFunction(Function &F) {

I just wrote an IR Verifier check that catches the following situation: ; RUN: not llvm-as %s -disable-output 2>&1 | FileCheck %s define void @f1() !dbg !4 { unreachable } ; CHECK: DISubprogram attached to more than one function define void @f2() !dbg !4 { unreachable } !llvm.dbg.cu = !{!1} !1 = distinct !DICompileUnit(language: DW_LANG_C99, file: !2) !2

Hi! We are currently working on a science project and implemented a FunctionPass that clones a function (more precisely a constructor of a struct/class) and adds a parameter. First, we create a new function with a new function type, which includes the newly added parameter: Function *NF = Function::Create(NewFTy, F.getLinkage(), F.getName() + "Cloned", F.getParent()); and after

Hi Philip, Thank you very much for your answer, the vector declaration example worked. I'm pretty sure the ValueToValueMapTy is the last thing I need because I even saw there is another function that could help me llvm*:*:RemapFunction <http://llvm.org/doxygen/namespacellvm.html#addf0183e92893bdbcde00fc9091dda93>; but my problem is that I don't know how to populate the
