* libguile/gc.h:
* libguile/gc.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_gc_live_object_stats): Deprecate; it hasn't
worked in the whole 2.0 series.
* libguile/inline.h:
* libguile/gc.h (scm_cell, scm_double_cell, scm_words): Move
declarations and definitions back here, from inline.h. It's more
natural.
* libguile/inline.c: Include gc.h as well.
* libguile/__scm.h (SCM_C_EXTERN_INLINE): Move this definition here,
from inline.h. We'd like to support inline function definitions in
more header files: not just inline.h.
(SCM_CAN_INLINE, SCM_INLINE, SCM_INLINE_IMPLEMENTATION): New
definitions.
* libguile/gc.h (SCM_GC_MALLOC, SCM_GC_MALLOC_POINTERLESS): Define these
wrappers, which redirect to the GC_MALLOC macros when building Guile,
and the scm_gc_malloc functions otherwise. A step towards getting
BDW-GC out of Guile's API.
* libguile/inline.h: Simplify, using SCM_INLINE,
SCM_INLINE_IMPLEMENTATION, and SCM_IMPLEMENT_INLINES. Also use the
new SCM_GC_MALLOC macros.
* libguile/gc-malloc.c (scm_realloc): Call the new
scm_gc_register_allocation() here. If we have to collect, do a
GC_gcollect_and_unmap.
* libguile/gc.c (scm_gc_register_allocation): Add a routine to track
steady-state mallocation, and cause gc to run if there is a high
mallocation rate.
(adjust_gc_frequency): Reset the bytes-until-GC countdown timer.
* libguile/bytevectors.c (scm_bootstrap_bytevectors): Remove a call to
scm_gc_protect_object.
* libguile/gc.h:
* libguile/gc.c (scm_init_gc_protect_object): Rename from
scm_init_storage, and just return void. Make the GC boot procs have
internal linkage.
* libguile/init.c: Adapt to the name change.
* libguile/gc.c (scm_gc): Don't use `scm_gc_running_p' as
an lvalue.
* libguile/gc.h (scm_gc_running_p): Define to 0.
* libguile/threads.h (scm_i_thread)[gc_running_p]: Remove.
* libguile/gc.c (protected_obj_count): Made `static'.
(scm_heap_size): Mapped to `heap-size' rather than `cell-heap-size'.
(scm_heap_free_size): New.
(scm_heap_total_allocated): New.
(scm_gc_stats): Rewritten. Return the (little) information available
from `libgc'.
(scm_gc_disable): New.
(scm_gc_enable): New.
(scm_storage_prehistory): Don't call `GC_add_roots ()' with
SCM_SYS_PROTECTS. Use `GC_is_visible ()' to check whether
SCM_SYS_PROTECTS is visible.
* libguile/gc.h (scm_gc_enable): New declaration.
(scm_gc_disable): New declaration.
(scm_gc_for_alloc): Removed.
(scm_gc_for_newcell): Removed.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-46
* libguile/__scm.h (SCM_DEBUG): add SCM_DEBUG_MARKING_API
* libguile/gc.h (SCM_SET_GC_MARK): depending on
SCM_DEBUG_MARKING_API crash if someone is touching markbits
outside regular hours.
Rename ensure_marking() to scm_i_ensure_marking().
* libguile/inline.h (scm_double_cell, scm_cell): only set mark bits
for debugging if SCM_DEBUG_MARKING_API is unset
* libguile/gc-mark.c: Issue deprecation warning if we are marking
outside of the GC mark phase.
* libguile/gc.c (finalizer_trampoline): New.
(scm_gc_register_finalizer): New.
* libguile/gc.h (scm_gc_register_finalizer): New declaration.
* libguile/guardians.c (finalize_guarded): Updated to the new prototype.
(scm_i_guard): Use `scm_gc_register_finalizer ()' instead of
`GC_REGISTER_FINALIZER_NO_ORDER ()'.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-23
* New file gc-segment-table.c: hold code for the segment table.
* Remove data that might be out of date; remove
scm_i_adjust_min_yield(). We don't store min_yields, since they
are only accurate at one point in time (when the sweep finishes).
We decide the min yield at that point from min_yield_fraction and
freelist->collected / freelist->swept
* Introduce scm_i_gc_heap_size_delta() replacing
scm_i_gc_grow_heap_p().
* Remove foo_1 fields containing penultimate results.
* After GC, count mark bit vector to discover number of live
objects. This simplifies hairy updates.
* Many formatting and layout cleanups.
* Fix in scm_i_sweep_card(): return the length of free_list returned,
rather than number of deleted objects.
* For mtrigger GCs: do not also run a full sweep after the gc() call, as
this is inconsistent with lazy sweeping.
* Remove scm_i_make_initial_segment().
* Use calloc in scm_i_make_empty_heap_segment() to save on
initialization code.
* New function scm_i_sweep_for_freelist() which sweeps, with proper
statistic variable updates.
* New segments are conceptually blocks with 100% reclaimable cells.
* Remove some useless constants/comments: SCM_HEAP_SIZE,
SCM_INIT_HEAP_SIZE, SCM_EXPHEAP, SCM_HEAP_SEG_SIZE
* Do not increment scm_cells_allocated() from the
scm_[double]cell(). This would be a race condition.
* Move some deprecation checks in separate functions to not distract
from main code flow.
* threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
scm_ia64_register_backing_store_base() instead of Linux-specific
implementations.
* gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
New declarations.
* gc.c (__libc_ia64_register_backing_store_base): Declaration
removed.
(scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
implementations for Linux and HP-UX.
* coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
and scm_ia64_register_backing_store_base() instead of
Linux-specific implementations.
* continuations.h (__libc_ia64_register_backing_store_base):
Declaration removed.
(scm_t_contregs): New "fresh" field.
* continuations.c (ia64_getcontext): Removed.
(scm_make_continuation): Use continuation fresh field instead of
interpreting getcontext return values (which isn't portable). Use
scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
instead of Linux-specific implementations.
(copy_stack_and_call): Use scm_ia64_register_backing_store_base()
instead of Linux-specific implementation.
* _scm.h (__ia64__): Also detect __ia64.
(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.
scm_gc_mallocated, for now.
(scm_init_storage): Initialize it.
* gc-malloc.c (descrease_mtrigger, increase_mtrigger): Use it.
* gc-mark.c (scm_gc_mark_dependencies): Call scm_i_string_mark,
scm_i_stringbuf_mark and scm_i_symbol_mark, as appropriate.
* gc-card.c (scm_i_sweep_card): Call scm_i_string_free,
scm_i_stringbuf_free and scm_i_symbol_free, as appropriate.
scm_t_bits. Updated all users.
(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
duplicating the code.
(SCM_CELL_OBJECT_LOC): New.
(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
(SCM_CELL_WORD_LOC): Moved to "deprecated.h".
