bc700b6dd3 First stab at the guardian implementation. Works fine at first glance! 
* libguile/guardians.c: Overhauled.  Removed the `tconc' structure.
  Much, much, simpler.
  (finalize_guarded): New function.

* libguile/init.c (scm_i_init_guile): Call `scm_init_guardians ()'.

89f423d5ad Tell `libgc' that we're using POSIX threads. This fixes Guile on PPC. 
* libguile/coop-defs.h: If `GUILE_PTHREAD_COMPAT' is defined, then define
  `GC_THREADS' and include <gc/gc.h> after <pthread.h>.

* libguile/coop-pthreads.h: Likewise.

  (SCM_WEAK_CELL_WORD_DELETED_P): Use `SCM_CELL_OBJECT' instead of
  `SCM_CELL_WORD'.

  (SCM_WEAK_CELL_WORD_DELETED_P): New.

  (scm_hash_fn_get_handle): Call `scm_fixup_weak_alist ()' on weak

  ()' for HANDLE when needed.

  pairs.

Ludovic Courtes
a82e795325 Fixed GC initialization and static roots.

  `GC_add_roots ()' as well.
  (scm_init_gc): Removed call to `GC_init ()'.

Ludovic Courtes
6a4be32986 Fixed garbage collection of ports: basics work (no SMOBs, no guardians, no WHT). 
* libguile/gc.c (scm_init_storage): Do not initialize SCM_I_PORT_TABLE
  here: this is done in `scm_ports_prehistory ()'.  This fixes the bug
  mentioned in the previous patch log.

* libguile/ports.c (scm_new_port_table_entry): Slightly clarified the
  code.

 2008-09-05 00:46:22 +02:00
Ludovic Courtes
fca4388748 First `working'' Guile! Crashes in flush-all-ports' (relates to SCM_I_PORT_TABLE). 
* libguile/gc.c (scm_gc_stats): Fixed so that it returns a relevant
  result instead of just `SCM_EOL'.

* libguile/ports.c: Include `assert.h'.  Don't include `malloc.h'.
  (scm_make_port_type): Use `scm_gc_realloc ()' instead of `realloc ()'.
  (scm_new_port_table_entry): Likewise.
  (scm_flush): Added an assertion on the port number.

c812243ba1 Small fixes. Gets to the REPL and `abort ()'s soon after. 
* libguile/inline.h (scm_cell): Re-added comment about the assignment
  order of CAR/CDR.

* libguile/srcprop.c (scm_make_srcprops): Use `scm_gc_malloc ()' instead
  of `malloc' + `scm_gc_register_collectable_memory ()'.

* libguile/threads.c (guilify_self_1): Likewise.
  (guilify_self_2): Likewise.
