* libguile/objcodes.h (SCM_OBJCODE_TYPE_MMAP)
(SCM_OBJCODE_TYPE_BYTEVECTOR, SCM_OBJCODE_TYPE_SLICE)
(SCM_OBJCODE_TYPE_STATIC): Enumerate objcode types instead of
expressing them as flags.
(SCM_OBJCODE_TYPE): Type is held in bits 8-15.
(SCM_OBJCODE_FLAGS): Flags are now shifted by 16 bits, not 8.
(SCM_MAKE_OBJCODE_TAG): New helper.
* libguile/continuations.c (STATIC_OBJCODE_TAG):
* libguile/control.c (STATIC_OBJCODE_TAG):
* libguile/foreign.c (STATIC_OBJCODE_TAG):
* libguile/gsubr.c (STATIC_OBJCODE_TAG):
* libguile/smob.c (STATIC_OBJCODE_TAG):
* libguile/objcodes.c (make_objcode_by_mmap, scm_c_make_objcode_slice)
(scm_bytecode_to_objcode): : Use SCM_MAKE_OBJCODE_TAG.
* libguile/smob.c: Instead of having special evaluator support for
applying smobs, we use the same strategy that gsubr uses, that smob
application should happen via a trampoline VM procedure, which uses a
special opcode (smob-apply). So statically allocate all of the desired
trampoline procedures here.
(scm_i_smob_apply_trampoline): Unfortunately there's no real place to
put the trampoline, so instead use a weak-key hash. It's nasty, but I
think the benefits of speeding up procedure calls in the general case
are worth it.
* libguile/smob.h (scm_smob_descriptor): Remove fields apply_0, apply_1,
apply_2, and apply_3; these were never public. Also remove the
gsubr_type field. Instead cache the trampoline objcode here.
(SCM_SMOB_APPLY_0, SCM_SMOB_APPLY_1, SCM_SMOB_APPLY_2,
SCM_SMOB_APPLY_3): Just go through scm_call_0, etc here.
* libguile/vm-i-system.c (call, tail-call, mv-call): Simplify. All
procedure calls are VM calls now.
(smob-call): New instruction, used in smob trampoline procedures.
* libguile/vm.c (apply_foreign): Remove. Yay!
* libguile/procprop.c (scm_i_procedure_arity): Refactor a bit for the
smob changes.
* libguile/gsubr.h (SCM_GSUBR_MAX): Restore this define, which specifies
the max number of args to a gsubr.
* libguile/smob.c: Remove local SCM_GSUBR_MAX define.
* libguile/tags.h (scm_tc7_gsubr): Return to the pool of unused tc7s, as
there are no more gsubrs. Yay :)
* libguile/programs.h (SCM_F_PROGRAM_IS_PRIMITIVE):
(SCM_PROGRAM_IS_PRIMITIVE): New flag and accessor.
* libguile/gsubr.c (create_gsubr):
* libguile/snarf.h (SCM_STATIC_PROGRAM): Give subrs a PRIMITIVE flag.
* libguile/smob.h:
* libguile/smob.c (scm_i_smob_arity): New internal procedure. Uses the
old GSUBR type macros, local to the file.
* libguile/procprop.c (scm_i_procedure_arity): Call out to
scm_i_smob_arity, and remove a gsubr case.
* libguile/gc.c (scm_i_tag_name):
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (scm_class_of):
* libguile/vm.c (apply_foreign):
* libguile/hash.c (scm_hasher):
* libguile/debug.c (scm_procedure_name):
* libguile/print.c (iprin1): Remove gsubr cases.
* libguile/gsubr.h (SCM_PRIMITIVE_P): Fix to work with the new VM
program regimen.
(SCM_GSUBR_TYPE, SCM_GSUBR_MAKTYPE, SCM_GSUBR_MAX, SCM_GSUBR_REQ)
(SCM_GSUBR_OPT, SCM_GSUBR_REST): Remove these macros, that are no
longer useful.
* libguile/gsubr.c (scm_i_gsubr_apply, scm_i_gsubr_apply_list)
(scm_i_gsubr_apply_array): Remove internal gsubr application
functions.
* libguile/smob.h: Regularize the SCM_SMOB macros, and make them all go
through some generic SMOB accessor macros.
* libguile/smob.c (scm_i_set_smob_flags): Remove, as it is unused.
* libguile/goops.c (scm_smob_class): Statically allocate it.
(create_smob_classes): Don't malloc(3) `scm_smob_class'.
* libguile/goops.h (scm_smob_class): Update declaration.
* libguile/smob.c (scm_make_smob_type, scm_set_smob_apply): When
checking whether GOOPS is initialized, check whether the first element
of SCM_SMOB_CLASS is non-zero.
* libguile/goops.c (create_smob_classes): Refer to
`SCM_I_MAX_SMOB_TYPE_COUNT' rather than 255 (which is wrong) or 256.
* libguile/smob.c (MAX_SMOB_COUNT): Alias for `SCM_I_MAX_SMOB_TYPE_COUNT'.
* libguile/smob.h (SCM_I_MAX_SMOB_TYPE_COUNT): New macro.
* libguile/goops.c (scm_smob_class): Statically allocate it.
(create_smob_classes): Don't malloc(3) `scm_smob_class'.
* libguile/goops.h (scm_smob_class): Update declaration.
* libguile/smob.c (scm_make_smob_type, scm_set_smob_apply): When
checking whether GOOPS is initialized, check whether the first element
of SCM_SMOB_CLASS is non-zero.
* libguile/goops.c (create_smob_classes): Refer to
`SCM_I_MAX_SMOB_TYPE_COUNT' rather than 255 (which is wrong) or 256.
* libguile/smob.c (MAX_SMOB_COUNT): Alias for `SCM_I_MAX_SMOB_TYPE_COUNT'.
* libguile/smob.h (SCM_I_MAX_SMOB_TYPE_COUNT): New macro.
* libguile/smob.c (scm_smob_prehistory): When initializing
SMOB_GC_KIND, pass 1 as the CLEAR_NEW_OBJECTS argument to
`GC_new_kind ()'. Without this, an assertion failure is
triggered in libgc's `reclaim.c'.
* libguile/smob.c (smob_mark): Check the 7-bit type tag and ignore those
whose type tag is not that of a SMOB in order to cleanly handle
free-list objects (this fixes a bug which showed up on SPARC64).
Also, don't mark & push ADDR itself.
(scm_gc_mark): Moved the definition and undefinition of
`CURRENT_MARK_PTR' and `CURRENT_MARK_LIMIT' here.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-30
* libguile/smob.c (scm_make_smob): Use `SCM_RETURN_NEWSMOB ()' instead of
`scm_cell ()' when instantiating the SMOB.

* libguile/smob.c (scm_i_finalize_smob): New.
* libguile/smob.h (SCM_NEWSMOB): Register `scm_i_finalize_smob ()' as a
finalizer for Z if its SMOB type has a free function.
(SCM_NEWSMOB3): Likewise.
(scm_i_finalize_smob): New declaration.

print.c, ports.c, mallocs.c, hooks.c, hashtab.c, fports.c,
guardians.c, filesys.c, coop-pthreads.c, continuations.c: Use
scm_uintprint to print unsigned integers, raw heap words, and
adresses, using a cast to scm_t_bits to turn pointers into
integers.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.
non-zero is returned from a port or smob free function.

appropriate. Return zero from smob and port free functions.
* debug-malloc.c (scm_malloc_reregister): Handle "old == NULL".

it is pointing to the putback buffer.
