Enable hardware breakpoints for gdbserver on Windows
When trying to use hardware breakpoints with gdbserver you get this error:
(gdb) hbreak main
Hardware assisted breakpoint 2 at 0x40162d: file gdb-9493.c, line 5.
(gdb) c
Continuing.
Warning:
Cannot insert hardware breakpoint 2.
Could not insert hardware breakpoints:
You may have requested too many hardware breakpoints/watchpoints.
It turns out the respective types just needed to be added to the
appropriate callback functions, because x86_dr_(insert|remove)_watchpoint
already handles them.
gdbserver/ChangeLog:
2020-05-15 Hannes Domani <ssbssa@yahoo.de>
* win32-i386-low.cc (i386_supports_z_point_type): Handle
Z_PACKET_HW_BP z_type.
(i386_insert_point): Handle raw_bkpt_type type.
(i386_remove_point): Likewise.
