Hello group, Per my posting on the Clang Newsgroup. I'm interested in doing some loop optimizations, towards this end I would like to add some custom Metadata to a Loop header. Loops in LLVM are represented using BasicBlocks, but unfortunately you can NOT add MetaData to a BasicBlock. Although you can add Metadata to an instruction. So I'm proposing to add the Metadata manipulation

Dear all, I am looking to output assembly comments in my emitPrologue() function, just for my own readability. Searching 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

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

Hello Duncan, Yes, I built it with assertions and I have also debug info.

Hi Alexandru, did you build LLVM with assertions enabled? If not then you should do. Ciao, Duncan.

Hello everyone, I was able to get all the execution paths between 2 points (basic blocks) in my program (with the condition to traverse a loop only once). I mapped all the basic blocks to integers and created a correspondent directed graph. I was able to get all the paths (a path is represented by an integer identifier). For my target program I have 72 paths, but the program hangs unexpectedly

As an update, it is a memory problem which I don't know how to fix. I tried to skip the problematic piece of code when in the case when the loop hangs. So I did something like : if( instr ) { LLVMContext& C = instr->getContext(); Value* values[cnt]; errs()<<"\ngy: \n"; if(!(desters==7)){ // this

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?

Hi, I don't know much about this issue, but this malloc error won't be solved by a change to delete[] or free. In fact, if you use the incorrect one for simple types, you may not notice it. The error you have seems to me like a memory corruption because you went out of bound and corrupted the memory somewhere, Valgrind may help you figure out what is going on. Cheers, Matthieu

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

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp

Hi Craig, On 03.07.19 17:33, Craig Topper wrote: > Don't the CreateICmp calls return a Value* with an i1 type? But then > they are added to an i8 type? Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly

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

Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!
