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