and none of them match the c/c++ names. However when calling GetName()
all that info is lost and i get back something like "unsigned short" or
"char*". On the calling side I have no way to turn that back into their
real types, I need this info to know if something is a (string)
character or if it's a 16bits integer, or for pointer types, if they
should be treated specials (some pointer to type-types are arrays while
others are not). C has no such distinction.

parser, or are you using DWARF?
I am emitting proper DWARF. It's just that LLDB ignores the "name" of
the dwarf records and several other things and makes presumptions on the
debugged language being C/C++/ObjC, ignoring what the debug info says a
type is really called and using it's own type names based on the bitsize
and dwarf flags.
