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.
