fd51e66190 attempt to handle steady-state mallocations better
* 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.

47ed8656db add SCM_HEAP_OBJECT_BASE
* libguile/tags.h (SCM_HEAP_OBJECT_BASE): New macro.  Given a SCM,
  returns a pointer to the start of its memory area on the heap.

21041372ed add SCM_{PACK,UNPACK}_POINTER
* libguile/tags.h (SCM_UNPACK_POINTER, SCM_PACK_POINTER): New macros.
  The old SCM2PTR and PTR2SCM were defined in such a way that
  round-tripping through a pointer could lose precision, even in the
  case in which you weren't interested in actually dereferencing the
  pointer, it was simply that you needed to plumb a SCM through APIs
  that take pointers.  These new macros are more like SCM_PACK and
  SCM_UNPACK, but for pointer types.  The bit representation of the
  pointer should be the same as the scm_t_bits representation.

* libguile/gc.h (PTR2SCM, SCM2PTR): Remove support for (old) UNICOS
  pointers.  We are going to try tagging the SCM object itself in the
  future, and I don't think that keeping this support is worth its
  cost.  It probably doesn't work anyway.

* libguile/backtrace.c:
* libguile/bytevectors.c:
* libguile/continuations.c:
* libguile/fluids.c:
* libguile/foreign.c:

ff670362aa scm_cell, scm_double_cell, scm_words back to gc.h
* 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.

4cf77f0946 simplify inline function infrastructure
* 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.

* module/ice-9/boot-9.scm:
* module/ice-9/deprecated.scm: Remove all deprecated code.  CPP defines
  that were not previously issuing warnings were changed so that their
  expansions would indicate the replacement forms to use,
  e.g. scm_sizet__GONE__REPLACE_WITH__size_t.

  The two exceptions were SCM_LISTN, which did not produce warnings
  before, and the string-filter argument order stuff.

  Drops the initial dirty memory usage of Guile down to 2.8 MB on my
  machine, from 4.4 MB.

82ae1b8eb3 Garbage collection cleanup.
* 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.

outside of marking stage.

5dbc6c0679 replace port table with weak hash table. This simplifies
memory management, and fixes freed cells appearing in
port-for-each output.

9a5fa6e98a * configure.in: New check for uca lib (needed for IA64 on HP-UX).
* 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.

b17e0ac397 * gc.h, gc.c (SCM_FREECELL_P): Removed for good.
(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.

(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.
