llvm-mirror/lib/IR/AsmWriter.h
Daniel Malea 22adabba07 Re-implement DebugIR in a way that does not subclass AssemblyWriter:
- move AsmWriter.h from public headers into lib
- marked all AssemblyWriter functions as non-virtual; no need to override them
- DebugIR now "plugs into" AssemblyWriter with an AssemblyAnnotationWriter helper
- exposed flags to control hiding of a) debug metadata b) debug intrinsic calls
