14.25.2 Enhanced support for C++ templates

This version of HP WDB includes these features to support C++ templates:

•Setting breakpoints in template class functions and template functions without having to specify details about the instantiation.

•The ptype command shows any one of the class instantiations.

A option -vin ptype command will now display the field offset and size information of a struct/union/class in addition to the default type information.

Syntax:

(gdb) ptype -v struct info

type = struct info /* off 0 bits, len 512 bits */ int i;

/* off 0 bits, len 32 bits */ char a[20];

/* off 32 bits, len 160 bits */ struct details d;

/* off 192 bits, len 256 bits */ int b : 2;

/* off 448 bits, len 2 bits */ int c : 3;

/* off 450 bits, len 3 bits */ < filler >
