# tests for misc. C++ method stuff
# Written by Satish Pai <pai@apollo.hp.com> 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.)
