[cfe-dev] patch: add friend information for class types and access modifiers for methods to debug info

[Alexander Herz]

Hi,

I've created these two patches which add support for the 
llvm::dwarf::DW_TAG_friend for class types and flags for the access 
modifier (public/private/protected) for methods to the debug info. The 
llvm_*.diff patch needs to be applied to the llvm, the other one to clang.

Having this information is interesting when analyzing assembler while 
using the dbg info to recover information.

I'm not sure this is the proper way to submit patches, pls tell me if I 
should open a request in some bug tracking tool or what ever.

Also it would be good to know if the patch is accepted or not.

Thx,
Alex
