Hi!
It is nice to be able to reload the pretty printers and convenience
functions from gdbhooks.py without exiting GDB: reloading cc1 takes
several seconds (plus, the debugging session is lost).
Previously:
(gdb) python import imp; imp.reload(gdbhooks);
RuntimeError: pretty-printer already registered: gcc
Fixing this turned out easier than I expected.
(gdb) py help (gdb.printing)
revealed, that we can pass replace parameter to register_pretty_printer
(which is False by default).
With the patch:
(gdb) python import imp; imp.reload(gdbhooks);
Successfully loaded GDB hooks for GCC
gcc/
* gdbhooks.py: Pass replace=True to
gdb.printing.register_pretty_printer.

OK?
BTW, perhaps I should also add a convenience function for 'import imp;
imp.reload(gdbhooks)' or something to that effect?
