* 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 (_initialize_dcache): Update text for `remotecache' to indicate it is obsolete.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. doc/ * 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'.
