I'll add this to TODO:
- add support for masks in watchpoints. The trick is that GDB does not
support a breakpoint mask in the remote protocol. One way to work around
this is to add a separate command "watchpoint_mask add/rem <addr>
<mask>", that
is run to register a list of masks that the gdb_server knows to use with
a particular watchpoint address.
Any other bright ideas?
The idea is to replace 0xfffffffu w/a mask looked up in a list using
address as a key...
if (packet[0] == 'Z')
{
if ((retval = watchpoint_add(target, address,
size, type-2, 0,
0xffffffffu)) != ERROR_OK)
{
if ((retval = gdb_error(connection,
retval)) != ERROR_OK)
return retval;
}
else
{
gdb_put_packet(connection, "OK", 2);
}
}
else
{
watchpoint_remove(target, address);
gdb_put_packet(connection, "OK", 2);
}
