...should give full debug information, but I still have the same result. I am aware of http://llvm.org/docs/SourceLevelDebugging.html , from where I can see that is quite easy to take the source line number from a metadata field. PS: for Allocas, it seems that I have to use findDbgDeclare method from DbgInfoPrinter.cpp. Thank you in advance ! -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Is there a way, from within an opt pass, to find the correspondence between an LLVM IR object and C source code (basically line number info similar to the one used with gcc + gdb to help debugging ), assuming either a llvm-gcc front end ? Sorry if this question was asked before. Thanks for your time. - Prakash

Same question here!

Hmm... if I do a print() on the result of getFileName(), I get i8 * getelementptr ([9 x i8]* @.str, i32 0, i32 0) back, but if I try to dyn_cast this to GetElementPtrInst it fails (returning null), so presumably I'm seeing a GetElementPtrConstantExpr... so how can I get at that constant i8 array without casting to a GetElementPtrInst, and with GetElementPtrConstantExpr being

Thanks Edwin. I found DebugInfo.cpp may be useful. Could you tell me which function I should call inorder to know the source file name and the line number for a particular instruction?
