Thiago Jung Bauermann e09342b536 2011-01-11 Sergio Durigan Junior <sergiodj@linux.vnet.ibm.com> ... Thiago Jung Bauermann <bauerman@br.ibm.com> Implement support for PowerPC BookE ranged watchpoints. gdb/ * breakpoint.h (struct breakpoint_ops) <resources_needed>: New method. Initialize to NULL in all existing breakpoint_ops instances. (struct breakpoint) <exact>: New field. (target_exact_watchpoints): Declare external global. * breakpoint.c (target_exact_watchpoints): New global flag. (update_watchpoint): Set b->type to bp_hardware_watchpoint and b->enable_state to bp_enabled before calling hw_watchpoint_used_count. (hw_watchpoint_used_count): Iterate over all bp_locations in a watchpoint. Call breakpoint's breakpoint_ops.resources_needed if available. (insert_watchpoint, remove_watchpoint): Use fixed length of 1 byte if the watchpoint is exact. (resources_needed_watchpoint): New function. (watchpoint_breakpoint_ops): Add resources_needed_watchpoint. (watch_command_1): Set b->exact if the user asked for an exact watchpoint and one can be set. (can_use_hardware_watchpoint): Add exact_watchpoints argument. Pass fixed length of 1 to target_region_ok_for_hw_watchpoint if the user asks for an exact watchpoint and one can be set. Return number of needed debug registers to watch the expression. * gdbtypes.c (is_scalar_type): New function, based on valprint.c:scalar_type_p. (is_scalar_type_recursive): New function. * gdbtypes.h (is_scalar_type_recursive): Declare. * ppc-linux-nat.c (ppc_linux_region_ok_for_hw_watchpoint): Always handle regions when ranged watchpoints are available. (create_watchpoint_request): New function. (ppc_linux_insert_watchpoint, ppc_linux_remove_watchpoint): Use create_watchpoint_request. * rs6000-tdep.c (show_powerpc_exact_watchpoints): New function. (_initialize_rs6000_tdep): Add `exact-watchpoints' boolean to the `set powerpc' and `show powerpc' commands. * target.h (struct target_ops) <to_region_ok_for_hw_watchpoint>: Mention documentation comment in the target macro. (target_region_ok_for_hw_watchpoint): Document return value. gdb/doc/ * gdb.texinfo (PowerPC Embedded): Document ranged watchpoints and the "set powerpc exact-watchpoints" flag.		2011-01-11 19:23:03 +00:00
