Implement TARGET_OBJECT_STACK_MEMORY.
* NEWS: Add note on new "set stack-cache" option.
* corefile.c (read_stack): New function.
* dcache.c (dcache_struct): New member ptid.
(dcache_enable_p): Mark as obsolete.
(show_dcache_enabled_p): Flag option as deprecated.
(dcache_invalidate): Update ptid.
(dcache_invalidate_line): New function.
(dcache_read_line): No longer check cacheable attribute, stack
accesses get cached despite attribute.
(dcache_init): Set ptid.
(dcache_xfer_memory): Flush cache if from different ptid than before.
Update cache after write.
(dcache_update): New function.
(dcache_info): Report ptid.
(_initialize_dcache): Update text for `remotecache' to indicate it
is obsolete.
* dcache.h (dcache_update): Declare.
* dwarf2loc.c (dwarf2_evaluate_loc_desc): Mark values on stack with
set_value_stack.
* frame-unwind.c (frame_unwind_got_memory): Ditto.
* gdbcore.h (read_stack): Declare.
* memattr.c (mem_enable_command): Call target_dcache_invalidate
instead of dcache_invalidate.
(mem_disable_command, mem_delete_command): Ditto.
* target.c (stack_cache_enabled_p_1): New static global.
(stack_cache_enabled_p): New static global.
(set_stack_cache_enabled_p): New function.
(show_stack_cache_enabled_p): New function.
(target_dcache): Make static.
(target_dcache_invalidate): New function.
(target_load, target_resume): Call target_dcache_invalidate
instead of dcache_invalidate.
(memory_xfer_partial): New arg object, all callers updated.
Check for existing inferior before calling dcache routines.
When writing non-TARGET_OBJECT_STACK_MEMORY, notify dcache.
(target_xfer_partial): Call memory_xfer_partial for
TARGET_OBJECT_STACK_MEMORY.
(target_read_stack): New function.
(initialize_targets): Install new option `stack-cache'.
* target.h: Remove #include of dcache.h.
(enum target_object): New value TARGET_OBJECT_STACK_MEMORY.
(target_dcache): Delete.
(target_dcache_invalidate): Declare.
(target_read_stack): Declare.
* top.c (prepare_execute_command): New function.
(execute_command): Call prepare_execute_command
instead of free_all_values.
* top.h (prepare_execute_command): Declare.
* valops.c (get_value_at): New function.
(value_at): Guts moved to get_value_at.
(value_at_lazy): Similarly.
(value_fetch_lazy): Call read_stack for stack values.
* value.c (struct value): New member `stack'.
(value_stack, set_value_stack): New functions.
* value.h (value_stack, set_value_stack): Declare.
* mi/mi-main.c (mi_cmd_execute): Call prepare_execute_command
instead of free_all_values.

* gdb.texinfo (Caching Data of Remote Targets): Update text.
Mark `set/show remotecache' options as obsolete.
Document new `set/show stack-cache' option.
Update text for `info dcache'.
