fix various problems with allocation statistics, track overhead properly
-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-03-20 Ben Wing <ben@xemacs.org>
* diagnose.el (show-memory-usage):
* diagnose.el (show-object-memory-usage-stats):
Further changes to correspond with changes in the C code;
add an additional column showing the overhead used with each type,
and add it into the grand total memory usage.
src/ChangeLog addition:
2010-03-20 Ben Wing <ben@xemacs.org>
* alloc.c:
* alloc.c (init_lrecord_stats):
* alloc.c (free_normal_lisp_object):
* alloc.c (struct):
* alloc.c (clear_lrecord_stats):
* alloc.c (tick_lrecord_stats):
* alloc.c (COUNT_FROB_BLOCK_USAGE):
* alloc.c (COPY_INTO_LRECORD_STATS):
* alloc.c (sweep_strings):
* alloc.c (UNMARK_string):
* alloc.c (gc_sweep_1):
* alloc.c (finish_object_memory_usage_stats):
* alloc.c (object_memory_usage_stats):
* alloc.c (object_dead_p):
* alloc.c (fixed_type_block_overhead):
* alloc.c (lisp_object_storage_size):
* emacs.c (main_1):
* lisp.h:
* lrecord.h:
Export lisp_object_storage_size() and malloced_storage_size() even
when not MEMORY_USAGE_STATS, to get the non-MEMORY_USAGE_STATS
build to compile.
Don't export fixed_type_block_overhead() any more.
Some code cleanup, rearrangement, add some section headers.
Clean up various bugs especially involving computation of overhead
and double-counting certain usage in total_gc_usage. Add
statistics computing the overhead used by all types. Don't add a
special entry for string headers in the object-memory-usage-stats
because it's already present as just "string". But do count the
overhead used by long strings. Don't try to call the
memory_usage() methods when NEW_GC because there's nowhere obvious
in the sweep stage to make the calls.
* marker.c (compute_buffer_marker_usage):
Just use lisp_object_storage_size() rather than trying to
reimplement it.
