+       (show_dcache_enabled_p): Flag option as deprecated.
+       (dcache_invalidate): Update ptid.
+       (dcache_invalidate_line): New function.

+       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.

+       is obsolete.
+       * dcache.h (dcache_update): Declare.
+       * dwarf2loc.c (dwarf2_evaluate_loc_desc): Mark values on stack with

+       * 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.

+       (value_fetch_lazy): Call read_stack for stack values.
+       * value.c (struct value): New member `stack'.
