fix memory usage stats to include pdumped objects -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-02-21 Ben Wing <ben@xemacs.org> * diagnose.el: * diagnose.el (show-object-memory-usage-stats): Fix errors preventing this from working properly, account for words like "entry" pluralized to "entries". src/ChangeLog addition: 2010-02-21 Ben Wing <ben@xemacs.org> * alloc.c: * alloc.c (FREE_FIXED_TYPE_WHEN_NOT_IN_GC): * alloc.c (struct): * alloc.c (tick_lrecord_stats): * alloc.c (tick_lcrecord_stats): * alloc.c (sweep_lcrecords_1): * alloc.c (COUNT_FROB_BLOCK_USAGE): * alloc.c (SWEEP_FIXED_TYPE_BLOCK_1): * alloc.c (free_cons): * alloc.c (free_key_data): * alloc.c (free_button_data): * alloc.c (free_motion_data): * alloc.c (free_process_data): * alloc.c (free_timeout_data): * alloc.c (free_magic_data): * alloc.c (free_magic_eval_data): * alloc.c (free_eval_data): * alloc.c (free_misc_user_data): * alloc.c (free_marker): * alloc.c (gc_sweep_1): * alloc.c (HACK_O_MATIC): * alloc.c (FROB): * alloc.c (object_memory_usage_stats): * alloc.c (Fgarbage_collect): * dumper.c: * dumper.c (pdump_objects_unmark): * lrecord.h: * lrecord.h (enum lrecord_alloc_status): Fixes to memory-usage-tracking code, etc. (1) Incorporate NEW_GC stuff into FREE_FIXED_TYPE_WHEN_NOT_IN_GC to avoid duplication. (2) Rewrite tick_lcrecord_stats() to include separate tick_lrecord_stats(); use in dumper.c to note pdumped objects. (3) Instead of handling frob-block objects specially in object_memory_usage_stats(), have SWEEP_FIXED_TYPE_BLOCK_1 increment the stats in lrecord_stats[] so that they get handled like other objects. (4) Pluralize entry as entries, etc.
