about any possible false positives.
(scm_debug_newcell): don't change cell type to `allocated'.
(scm_debug_newcell2): ditto.
(scm_gc_for_newcell): ditto.
(scm_gc_mark): remove the tc16_allocated case.
(scm_init_struct): First arg to scm_make_vtable_vtable should be a
string, not a symbol. (`make-vtable-vtable' needs to append this
string to another string and then pass it through
`make-struct-layout'.)
libguile must use the prefix "libguile/" in path names since inly
the top-level source directory is on the include list. (That, in
turn, is because we want to distinguish between system header
files and hedares files internal to libguile.)
also here. (This is supposed to make sure that scmconfig.h is
built before all sources in order to prevent that everything has
to be rebuilt again. Hope it works---I'm just guessing. :)
account, but keeping more or less the same values as previously.
added some simple helper macros.
(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
into account.
(BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
current_mark_space_offset, mark_space_head, get_bvec,
clear_mark_space): new functions and supporting variables, types
and macros that implement mark space management.
(scm_igc): clear the mark space (all of it) before beginning the
mark phase.
(scm_gc_mark): changed the tests for rogue cells, much simplified
throughout (no different mark bit locations to worry about now).
(scm_mark_locations): don't consider card header cells.
(scm_cellp): ditto.
(scm_gc_sweep): simplified.
(init_heap_seg): changed to take cards into account.
scm_get_internal_run_time but returns a long. it's used by the GC
for timekeeping, since with scm_get_internal_run_time there is a
(extremely theoretical) possibility of consing.
(scm_get_internal_run_time): redefined in terms of
scm_c_get_internal_run_time.
* stime.h: added prototype for scm_c_get_internal_run_time.
sweep time, total marked cells, total swept cells, and number of
times GC was invoked.
(gc_start_stats): renamed from scm_gc_start, made static, taught
to init the new stats.
(gc_end_stats): renamed from scm_gc_end, made static, taught to
calculate the new stats.
(scm_igc): don't call gc_start_stats unless we are sure that we
are indeed going to collect. also, added some timekeeping between
the mark and sweep phases.
(scm_gc_sweep): count number of cells we sweep as we go.
* gc.h: removed prototypes for scm_gc_{start,end}.
