'total-cells-allocated in gc-stats output. This allows profiling
of a program's memory use.
* gc-segment.c (scm_i_sweep_some_cards): update
scm_gc_cells_allocated_acc when sweeping happens.
* gc.h: add scm_gc_cells_allocated_acc, scm_last_cells_allocated.
(scm_block_gc, scm_gc_heap_lock): Removed. Removed all uses.
(scm_gc_running_p): Now a macro that refers to the scm_i_thread
field.
(scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen
recursively.
(scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
scm_gc_running_p. Do not run the scm_after_gc_c_hook.
(scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
scm_after_gc_c_hook here.
(scm_gc_for_new_cell): Set scm_gc_running_p here and run the
scm_after_gc_c_hook when a full GC has in fact been performed.
(scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
* gc-segment.c (scm_i_get_new_heap_segment): Do not check
scm_gc_heap_lock.
* gc-malloc.c (scm_realloc, increase_mtrigger): Set
scm_gc_running_p while the scm_i_sweep_mutex is locked.
* gc-segment.c (scm_i_all_segments_statistics): new function.
(scm_i_heap_segment_statistics): new function
* gc.c (s_scm_gc_live_object_stats): new GUILE callable: return
statistics on the number of live objects of each type.
* gc-card.c (scm_i_tag_name): new function.
(scm_i_card_statistics): new function.
for sanity.
* gc-malloc.c (scm_gc_init_malloc): check user settings for
sanity.
(scm_gc_register_collectable_memory): prevent overflow of memory
counts.
* gc-freelist.c (scm_init_freelist): check user settings for sanity.
* gc-malloc.c (scm_gc_register_collectable_memory): use floats;
these won't ever wrap around with high memory usage.
* gc-freelist.c: include <stdio.h>
* gc-malloc.c: add DEBUGINFO for mtrigger GCs.
* gc-malloc.c (scm_gc_register_collectable_memory): use floats;
these won't ever wrap around with high memory usage.
* gc-malloc.c: add DEBUGINFO for mtrigger GCs.
* gc-malloc.c (scm_calloc): try to use calloc() before calling
scm_realloc().
* gc-segment.c (scm_i_initialize_heap_segment_data): remove card
init loop; handle this from scm_init_card_freelist()
* gc-card.c (scm_init_card_freelist): init bit vector here.
malloc.
* gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
only use SCM_MIN_HEAP_SEG_SIZE.
* ports.c (scm_add_to_port_table): add backwards compatibility
function
* ports.h: use scm_i_ prefix for port table and port table size.
* gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
* gc.c (scm_i_expensive_validation_check): separate expensive
validation checks from cheap ones.
