# Test ptype of a class.
#
# Different C++ compilers produce different output. I build up regular
# expressions piece by piece to accommodate all the compilers that I
# have seen: gcc 2.95.3, gcc 3.3.2 (ABI 1), gcc 3.4 prerelease (ABI 2);
# and all the debug formats I have seen: dwarf-2 and stabs+.
#
# A complicated class declaration looks like this:
#
# class A : public virtual V { // re_class
# private:
# V * _vb$V; // re_vbptr
# int a; // re_fields
#
# public: // re_access_methods
# A & operator=(A const &); // re_synth_gcc_2
# A(int, A const &); // ...
# A(int); // ...
# virtual int f(void); // re_methods
# }
#
# RE_CLASS matches the class declaration. C++ allows multiple ways of
# expressing this.
#
# struct ... { private: ... };
# class ... { private: ... };
# class ... { ... };
#
# RE_VBPTR matches the virtual base declarations. gcc 2.95.3 sometimes
# emits these, but gcc 3.X.Y never emits these. The name depends on the
# debug format.
#
# RE_FIELDS matches the data fields of the class.
# RE_METHODS matches the methods explicitly declared for the class.
#
# RE_SYNTH_GCC_2 and RE_SYNTH_GCC_3 match the optional synthetic methods
# of the class. gcc -gstabs+ emits these methods, and gcc -gdwarf-2
# does not.
#
# RE_ACCESS_METHODS is an access specifier after RE_FIELDS and before
# the methods (explicit methods and/or synthetic methods).
# There is also an RE_ACCESS_FIELDS.
#
# When I get HP-UX aCC, I hope that I can just add RE_SYNTH_ACC_NNN.
#
# Yet another twist: with gcc v2, ctor and dtor methods have a hidden
# argument in front, the "in-charge" flag. With gcc v3, there is no
# hidden argument; instead, there are multiple object functions for
# each ctor and dtor.
