23 # This file is part of the gdb testsuite
26 # 0. method arguments are correct
27 # 1. access to class data members inside method scopes
28 # 2. correct param types for methods in ptype.
29 # 3. const and volatile methods
31 # (#0 and #1 above relate to an HP specific problem -- GDB must correctly
32 # integrate FPARAM symbols in HP debug info into the local var list
33 # for the function or method's block.)
