8.8 The ‘@’ Type Descriptor

The ‘@’ type descriptor is used for a pointer-to-non-static-member-data type. It is followed by type information for the class (or union), a comma, and type information for the member data.

The following C++ source:

typedef int A::*int_in_a;

generates the following stab:

.stabs "int_in_a:t20=21=@19,1",128,0,0,0

Note that there is a conflict between this and type attributes (see The String Field); both use type descriptor ‘@’. Fortunately, the ‘@’ type descriptor used in this C++ sense always will be followed by a digit, ‘(’, or ‘-’, and type attributes never start with those things.
