[llvm-commits] DebugInfoBuilder - rough sketch

I've attached a patch file for the DebugInfoBuilder class. This is a
working prototype, meant for criticism and comment, and is not intended
as an actual patch for submission. The interface is incomplete and there
are no unit tests as of yet.
The DebugInfoBuilder class is a utility class for creating source level
debugging descriptors. It is inspired by IRBuilder.
Some of the unresolved issues include:
1) The current design allows the instance of the DebugInfoBuilder to be
reused with multiple modules. Calling SetModule() will set the current
module context, and install the basic anchors if they are not already
The reason why it was done this way was to make the usage of the class
similar to the way IRBuilder is used. However, a somewhat simpler design
would be a "use-once" instance, that took the module reference as a
2) The .cpp file contains a cut & pasted definition of LLVMDebugVersion.
Obviously, this should be included from a header; The reason for the
clone is to avoid creating a dependency on the CodeGen lib. I recommend
that the definition of LLVMDebugVersion be moved out of
MachineModuleInfo and into some more globally accessible header file.
