is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
__scm.h. Let's try this out and dump the old code after the
threads reorganization.
(set-tick-rate, set-switch-rate): Conditionally removed.
made SCM values into pointers. This turned an arithmetic
computation of the address of the vcell into a pointer-arithmetic
one, thereby screwing up marking of structs.
Bugfix 2: Removed incompletely introduced loop variable `j' used
when protecting the tail array of a struct.
prediction.
(SCM_MAX): New macro.
(scm_freelist_t): New field: collected_1. Previous amount of
collected cells.
(gc_sweep_freelist_finish): Trigger based on two last values of
freelist->collected to avoid unnecessary allocation due to
temporary peaks.
trigger adjustmeant: Take yield (freed cells) for all freelists
into account.
(SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
to 50000 cell heap with 45% trigger.
(scm_gc_cells_collected): Reintroduced.
(SCM_HEAP_SIZE): New macro.
(scm_gc_sweep): Reintroduced correct computation of
scm_cells_allocated.
(scm_freelist_t): Corrected commentary for field `cluster_size':
Clustersize counts objects, not cells; New member
`clusters_allocated'.
* gc.h: (typedef struct scm_freelist_t) remove from here.
* gc.c: (CELL_UP, CELL_DN) make these macros take additional
parameter (the span).
(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
(typedef struct scm_freelist_t) move here from gc.h, it had no
business being externally visible.
(typedef struct scm_heap_seg_data_t) renamed from
scm_heap_seg_data, to be style-compliant.
(scm_mark_locations) if the possible pointer points to a
multy-cell, check that it's properly aligned.
(init_heap_seg) alighn multy-cells properly, work with the
assumption that the segment size divides cleanly by cluster size
(so that there's no spill).
(round_to_cluster_size) new function.
(alloc_some_heap, make_initial_segment) use round_to_cluster_size
to satisfy the new init_heap_seg invariant.
