Yeah.  GDB doesn't do that sort of thing, involving
basically disassembling the instructions and grokking
what they do.

Well it does, in some special and limited circumstances
when it can't be avoided, but not in general.  And those
cases where it does it are very fragile and difficult to
maintain.  In general we'd like to have gdb do that kind
of thing less, not more.
