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 -v in 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 */
