...e 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 the instruction via one of it’s Create() routines and then call `setDebugLoc()` to it. I propose the addition of a DebugLoc parameter in the *::Create() instruction constructors. This could be in the form of a pure DebugLoc variable or possibly an `Instruction *InheritLocationFromInst` one Some pros of this idea are: - Easier to create instructions with debug location....

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 ───── http://www.cowlark.com ─────...

...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 = DebugLoc::get(newLine, newCol, N); Inst->setDebugLoc(Loc); I read the DebugLoc back by using const DebugLoc D = Inst->getDebugLoc(); unsigned Line = D.getLine(); outs() << Line <<"\n"; But I can't set the debug info correctly. How can I change the debug info correctly through llvm pass? Thanks Riyad -----...

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 code , right ? And also I want the compiler can do some inline optimization to my program. So I have to give this CallInst a DebugLoc.... What would happen if the DebugLoc of an Inst...

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

You may want to check out Instruction::setDebugLoc(). llvm/Support/DebugLoc.h and llvm/Analysis/DIBuilder.h will likely be helpful as well.

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

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 = token...

...into an SDNode in the DAG then later into a MachineInstr. I'd already attached my own MDNodes to IR instructions I was interested in. I wanted to propagate that info to the final binary. I Added a field to the SelectionDAGBuilder holding the current metadata which I update in SelectionDAGISel::SetDebugLoc() for every IR instruction. Next, in SelectionDAGBuilder::visit() i transfer the current instruction's metadata from the DAGBuilder to the instruction's SDNode. In InstrEmitter::EmitNode() I copy the metadata from the SDNode to the MachineInstr. DwarfDebug::endModule() creates my user-def...

...e 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 ,and insert !dbg appending an instruction. 2. LLVM::Instruction::setMetadata(...) => insert the metadta and !dbg appending an instruction. 3. DIBuilder::insertDeclare(...) => insert variable declare (like @llvm.dbg.declare) an...

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.:
