Many DI-related bugs are caused by missing Debug Location in an instruction created in a transformation. Most of the time the fix is trivial once you found where the culprit instruction is created (https://reviews.llvm.org/D50263). Currently, when you create a new Instruction, in order to give it DL you have to either use an IRBuilder that is previously set to the correct DL or “manually” create

I'd like my compiler to emit proper line number information. The docs talk about Instruction::setDebugLoc(), but that method doesn't actually have to be in my 2.7 LLVM Debian package. What's the correct way of doing this? In addition, can anyone point me at an example of how to emit a comment attached to an instruction (or function)? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─────

Hi All, I want to change debug information of an llvm instruction so that the modified debug info is subsequently passed to executable binary. So if I use "addr2line" utility on the binary, it will return my modified debug information. I've tried to change by using the following code snippet: MDNode *N = Inst->getMetadata("dbg"); DebugLoc Loc =

Thanks for the help. I thought I'd solved the problem (setting the line number information in the instruction metadata) by inserting my own function for setting line number in llvm/Support/DebugLoc.h. I have added a function setLine(unsigned) in DebugLoc class. The function simply sets the LineCol variable as needed. But there is a problem. Whenever I'm checking the line number(calling

Hi, I'm trying to replace function call with call to wrapper(function_name, num_args, ...), where varargs hold args of original call. Function* launch = Function::Create( TypeBuilder<int(const char*, int, ...), false>::get(context), GlobalValue::ExternalLinkage, "kernelgen_launch_", m2); { CallInst* call = dyn_cast<CallInst>(cast<Value>(I)); if

Hi I want to insert some functions into the llvm bitcode ir files. So I use IRBuilder and CreateCall(). But it how error : inlinable function call in a function with debug info must have a !dbg location. I don't know what DebugLoc should I give the new CallInst to setDebugLoc. I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source

This is maybe a minor issue, but it is obvious when one looks at debug info produced by clang. Such records are normally created by the code like this: Instruction->setDebugLoc(llvm::DebugLoc::get(Line, Column, Scope)); and it appears that Column is always zero. Yuri

Generally, a good strategy is to look at what Clang generates for similar code and mimic that in your IR generator. -- adrian

Oh! I made a mistake by not using setDebugInfo() function present in the Instruction class. Now it's working fully. So, the solution is:- To set the line number for an instruction - 1. Add a function in DebugLoc class located in llvm/Support/DebugLoc.h. Set the line number there to the private variable called LineCol. 2. Call the added function. And then pass the modified DebugLoc object to

Hi, I am new to LLVM infrastructure. Recently I am trying to set the debug info for an instruction. The main aim is to set the source line number of an instruction. Can anyone please show how to do that? I think that setMetadata method in Instruction class is to be used. But how do I create MDNode* consisting of desired source line number. Source line number can be extracted from the

Hi Dimitry, This makes sense if you think about it from the perspective that the string you want passing must be passed at runtime, and so can't use a const char * from compile time. You need to make the string visible in the compiled image, and use that as the argument. A string is an array of 8-bit integers, so you need to create a ConstantArray. Value *v = ConstantArray::get(Context,

Here's what my code looks like for setting the debug location (some details removed for clarity): void CodeGenerator::setDebugLocation(const SourceLocation & loc) { if (loc != dbgLocation_ && dbgContext_.isScope()) { dbgLocation_ = loc; if (loc.file == NULL) { builder_.SetCurrentDebugLocation(llvm::DebugLoc()); } else if (loc.file == module_->moduleSource()) { TokenPosition pos = tokenPosit...

hi Devang and thanks for the tips, i finally managed to fit all the pieces together into something that seems to work. It's probably not the best (or even correct!) way of doing it but here's a brief overview for reference: An instruction in the LLVM IR gets converted into an SDNode in the DAG then later into a MachineInstr. I'd already attached my own MDNodes to IR instructions I

As title. I try to write a pass to covert the bitcode with no debug info to the bitcode with debug info. I use DIBuilder as a LLVM API so that I can generate DI(Debug info). Now I have some DIDescriptor , e.g. DIVariable ,DICompileUnit, DISubprogram , I can use some function to insert metadata. 1. LLVM::Instruction::SetDebugLoc(...) => insert the debug info location like DILexicalBlock

Hi list, I found relevant documentation regarding DebugInfo creation in the LLVM IR bytecode. It can be done for compileunits, functions, and other constructs, with the help of DIBuilder class. However I can't save debug information related to individual llvm::Instructions. I tried DebugLoc, DILocation setting directly with setMetadata(). I tried other ways, for e.g.:
