+
+ the following changes let Guile get rid of the `allocated' cell
+ state.
+
+ * smob.c (scm_smob_prehistory): don't init the "allocated" smob
+ type.
+
+ * tags.h (scm_tc16_allocated): removed.
+
+ * gc.h: removed now-obsolete comments about the `allocated' cell
+ state.
+ (SCM_NEWCELL): don't change cell type to `allocated'.
+ (SCM_NEWCELL2): ditto.
+
+ * gc.c (scm_mark_locations): mark freecells too, and don't worry
+ about any possible false positives.
+ (scm_debug_newcell): don't change cell type to `allocated'.
+ (scm_debug_newcell2): ditto.
+ (scm_gc_for_newcell): ditto.

+
+2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
+
+ * gdbint.c (gdb_print): Removed superfluous macro definition.
+
+ * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
+ (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'.)
+
+ * stacks.c (scm_init_stacks): Pass a string, not a layout object,
+ to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
+
+ * struct.c (scm_make_struct_layout): Removed reference to
+ "read-only string" in comment; Check that argument is a string.
+ (scm_make_vtable_vtable): Check that argument is a string.
+
+ * environments.c (scm_init_environments): All internal includes in
+ 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.)
+
+ * strings.c (scm_make_shared_substring, scm_read_only_string_p):
+ Deprecated.
+ (scm_string_length, scm_string_ref, scm_substring,
+ scm_string_append): Don't accept symbols as arguments (R5RS).
+
+2000-08-25 Neil Jerram <neil@ossau.uklinux.net>

+ * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
+ 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. :)
+
+ * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.

+
+ * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in

+
+ this changes the Guile GC to use cards (aka "chunklets").
+ (most of the ideas and some of the code are by Greg Harvey, though
+ the code is probably unrecognizable now. the original chunklet
+ proposal, way back, is by Dale Jordan).
+
+ * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
+ SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
+ some (most) of these are probably going to be deprecated.
+
+ * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
+ locations anymore.
+ (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
+ cards and bvecs (bit-vectors).
+
+ * gc.c: (scm_default_init_heap_size_*): defined to take cards into
+ 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.

+ 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.
+

+
+ * stime.c (scm_c_get_internal_run_time): new function, same as
+ 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.
+
+ * gc.c (scm_gc_stats): add more obscure stats, such as: mark 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.

+ 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}.

+ mismatch is discovered.

+
+ * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

+ environment specifier as second arg. `eval' hereby becomes R5RS
+ compatible.
+ (scm_i_eval_x, scm_i_eval): New functions (replace
+ scm_eval_3).
+ (scm_eval2, scm_eval_3): Deprecated.

+ The following changes are intended to ensure that struct instances
