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.
