Hello everybody, I want to get the line number of an instruction (and also of a variable declaration - alloca and global). The instruction is saved in an array of instructions. I have the function:     Constant* metadata::getLineNumber(Instruction* I){         if (MDNode *N = I->getMetadata("dbg")) { // this if is never executed             DILocation Loc(N);             unsigned Line = Loc.getLineNumber();             return ConstantInt::get(Type::getInt32Ty(I->getContext()), Line);         }   // else {         ...

Hi, I found the following at http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } Does this also work for release 2.7? I did not see the same thing at the documentation for release 2.7. Thanks, Guoliang -------------- next part -------------- An HTML attachment was scrubbed... URL: <http...

Hi all, I used to extract the debug information from an LLVM Instruction in the following way: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } As specified also at http://llvm.org/docs/SourceLevelDebugging.html <http://llvm.org/docs/SourceLevelDebugging.html> However, looks like that the instruction " DILocation Loc(N);” is not valid anymore, Sin...

...uction. 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 does not have any function like setLinenumber. Abhirup Ghosh M. Tech Department of Computer Science & Engg.

Hi all, I need to know the line number range of a function. The start of the function line number can be found by the definition point, which is stored at the subprogram metadata: DISubprogram::getLineNumber(). However, there is no API (or the metadata in the first place) to know the end of the function. I have to visit all the instructions of the function and maintain the *max*line number of the instructions. I use the inst_begin(func): inst_end(func) as the iterator. But I don't think it's...

Dear LLVMers, I'm updating some code to use the new LLVM 2.7 API. One piece of this code uses the findStopPoint() function to find the source filename and line number information of an instruction. What is the best way to do this under LLVM 2.7 now that the stop point intrinsic has been removed? It appears that the debug information is attached as metadata, but what is the easiest way

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