[LLVMdev] Obtaining a GlobalVariable from an MDNode (original) (raw)

DebugInstrumentation.cpp. Line 246 does the following:

if (DIGlobalVariable(*NMD->getOperand(i)).getGlobal() == GV) {

(Where i is an unsigned loop variable and NMD is a NamedMDNode.) Apparently, the compiler rejected the cast from an MDNode (the result of getOperand(i)) to a DIGlobalVariable. Also, it appears that getGlobal() doesn’t exist anymore in the DIGlobalVariable doxygen.

I’ve been looking over the doxygen and I can’t seem to find a way to do this. Which source file does this? I don't recall off-hand where SAFECode does this and why. Regards, John Criswell
