Detailed Description

Utility to find all debug info in a module.

DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder uses processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs.
