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