And what about with llvm-gcc ? Many thanks in advance, Aaron

I will look into this when I get some spare time. Aaron
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 line number and source file information for the call.
//
const DbgStopPointInst * StopPt = findStopPoint (CI);
Value * LineNumber;
Value * SourceFile;
if (StopPt) {
LineNumber = StopPt->getLineValue();
SourceFile = StopPt->getFileName();
}
