Hi, I have bitcode files built by LLVM v3.3 and need to process them using v3.4 tools. While I don't expect a lot of backward compatibility in LLVM, luckily it seems everything's working fine, except for reading source line information attached to instructions. I use this piece of code [0] to get source line information. For v3.4, instruction.getMetadata returns NULL. I used llvm-dis to

Thanks Eric, but could you give me a little bit more hints or pointers please? I looked into DebugInfo.h, but I'm still not sure how to start. It sounds like I'd have to somehow manually extract metadata nodes from an instruction.

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

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

Hi All, Now, in llvm trunk we support custom metadata, which can be attached with llvm instructions. One of the user is "debugging information". This user is special (not just because it is in llvm svn tree:) because whenever debug info is available, it is likely that corresponding metadata is attached with almost all instructions. In other words, usually it is all or nothing. This

I'm using the 2.6 release, thinking I was up to date, but its debug output doesn't look anything like what's described in the above link. It appears to document the upcoming 2.7 version, which

Hi All, I hope to get some information about functions in a bitcode file. Say, if we have a function foo(), and the bitcode file is generated by a single source file, then I want to get the line number foo() locates in that source file. If the bitcode file is linked by multiple bitcode files, is it possible to also get which file foo() locates in? Thanks, Chen -------------- next part

Dear All, To add to this, what you want to do is find the appropriate debug stop point intrinsic and then use it to look up the information for that instruction. Here is some sample code from SAFECode that finds the debug information associated with a CallInst (LLVM call instruction) held in the variable CI. It uses the findStopPoint() function in llvm/Analyis/DebugInfo.h: // // Get the
