# tests for misc. C++ method stuff

# Written by Satish Pai  1997-07-08

# This file is part of the gdb testsuite

# This tests:

# 0. method arguments are correct

# 1. access to class data members inside method scopes

# 2. correct param types for methods in ptype.

# 3. const and volatile methods

# (#0 and #1 above relate to an HP specific problem -- GDB must correctly

# integrate FPARAM symbols in HP debug info into the local var list

# for the function or method's block.)
