Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method? Also, I...

I think the better solution should be: LLVMContext& C = is->getContext(); Value *values[] = { ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*), MDString::get(C, *"path"*) }; lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values)); So that you can take advantage of the type system of LLVM bitcode, and don't have to cast the integers from/to strings by yourself.

Dear llvm-ers, I am trying to attach a customized metadata to llvm instructions. Let's say, I want to attach some number to each instruction. I am trying to use void Instruction::setMetadata(unsigned KindID, MDNode* Node) but I am not sure how to create a brand new instance of an MDNode. Do you have any code samples demonstrating how to do that? Due to some tool dependencies, I am using LLVM 2.7 Thank you, Oksana -------------- next part -------------- An HTML attachment was scrubbe...

Hi, I want to remove metadata from an instruction. Is there any way doing this in my pass? Regards, Kyriakos -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20130815/08200e23/attachment.html>

Hi, an older thread about removing metadata says to use “setMetadata(Kind, nullptr)” to drop the metadata from the instruction. I have using this method without success. When I look at inside the IR code the metadata are still there, any idea why is that? Thanks. Best, Simone

...mentation 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.: insertDbgValueIntrinsic(). If I set invalid parameters for the call, then the LLVM passes warn me, correctly, so at least I see in the log, that LLVM tries to assign debuginfo to given instruction. If however I set valid parameters, then I suppose, that the passes d...

In https://reviews.llvm.org/D26229 I've proposed dropping support for old style scalar TBAA metadata. Here is the proposed commit message: "We've had support for auto upgrading old style scalar TBAA access metadata into the "new" struct path aware TBAA metadata for 3 years now. The only way to actually generate old style TBAA was explicitly through the IRBuilder API. I

...earching for a way to do this found me this thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/043722.html, which says that the best way to output comments from somewhere like emitPrologue() is to: 1. Create an MDString for the comment. 2. Attach it to an LLVM instruction using setMetadata(). 3. Add a new member to MachineInstr to hold the metadata, and attach it when converting LLVM instructions. 4. Update AsmPrinter to read off the metadata and output it as an assembly comment. Is this the only (and correct) way to do this? If so, I am having trouble attaching the...

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 instruction-debug-info using getMetadata method and then using getLineNumber method from DILocation class. Unfortunately DILocation class doe...
