* configure.in: add --disable-arrays option, probably temporary.
* the following changes allow guile to be built with the array
"module" omitted. some of this stuff is just tc7 type support,
which wouldn't be needed if uniform array types were converted
to smobs.
* tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
HAVE_ARRAYS.
(scm_tag): don't check array types unless HAVE_ARRAYS.
* sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
remove the unused array types.
* (scm_stable_sort, scm_sort): don't support vectors if not
HAVE_ARRAYS. a bit excessive.
* random.c (vector_scale, vector_sum_squares,
scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
* gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
gh_uniform_vector_length, gh_uniform_vector_ref):
don't define unless HAVE_ARRAYS.
(gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
gh_scm2doubles):
don't check vector types if not HAVE_ARRAYS.
* eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
don't support the array types unless HAVE_ARRAYS is defined.
* tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
* read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
defined (this should use read-hash-extend).
* ramap.c, unif.c: don't check whether ARRAYS is defined.
* vectors.c (scm_vector_set_length_x): moved here from unif.c. call
scm_uniform_element_size if HAVE_ARRAYS.
vectors.h: prototype too.
* unif.c (scm_uniform_element_size): new procedure.
* init.c (scm_boot_guile_1): don't call scm_init_ramap or
scm_init_unif unless HAVE_ARRAYS is defined.
* __scm.h: don't define ARRAYS.
* Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
moved here from libguile_la_SOURCES.
* Makefile.am (ice9_sources): add arrays.scm.
* boot-9.scm: load arrays.scm if 'array is provided.
* arrays.scm: new file with stuff from boot-9.scm.
associated with subrs.
(SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
SCM_SUBR_DOC): New macros.
(scm_subr_table): New variable.
(scm_mark_subr_table): New function.
* init.c (scm_boot_guile_1): Call scm_init_subr_table.
* gc.c (scm_gc_mark): Don't mark subr names here.
(scm_igc): Call scm_mark_subr_table.
* snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
* procs.c, procs.h (scm_subr_p): New function (used internally).
* gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
* objects.c, objects.h (scm_primitive_generic): New class.
* objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
* print.c (scm_iprin1): Print primitive-generics.
* __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
* eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
primitives). NOTE: This means that it is now *required* to use
SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
obscured representation that will be removed in the future anyway,
so backward compatibility is no problem here).
* numbers.c: Converted most numeric primitives (all but bit
comparison operations and bit operations) to dispatch on generic
if args don't match.
* eval.c, eval.h (scm_eval_body): New function.
* objects.c (scm_call_generic_0, scm_call_generic_1,
scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
functions.
* eval.c (SCM_CEVAL): Apply the cmethod directly after having
called scm_memoize_method instead of doing a second lookup.
* objects.h (scm_memoize_method): Now returns the memoized cmethod.
* procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
scm_sysintern so that the binding connected with the subr name
isn't cleared when we give set = 0.
apply).
(scm_operator_p): Added.
(scm_sym_atdispatch): Added.
(scm_set_object_procedure_x): Modified to handle the new style
generic functions.
(scm_object_procedures): New debugging procedure.
(scm_class_keyword): Removed. (Class is automatically created by
make_smob_classes.)
(scm_smob_class): Array of smob classes indexed by smobnum.
(scm_make_extended_class): "Plugin" function pointer for creation
of wrapper classes for smob and struct types.
(scm_class_of): Handle compiled closures. (Currently regarded as
<procedure>.);
Use scm_smob_class to handle smob types;
Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
through scm_smob_class;
Handle structs.
* Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
"kw" --> "keywords" everywhere.
(I doubt that this will cause big compatibility problems since the
application interface is unaffected.)
make_class_object; exported; error checking moved to
scm_make_class_object and scm_make_subclass_object.
(scm_make_class_object, scm_make_subclass_object): Use
scm_i_make_class_object.
(scm_make_subclass_object): Let the subclass have same metaclass
as the superclass.
Some indentation fixes.
* objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
longer a user field; New field: class_flags.
* objets.c, objects.h: New metaclass: scm_metaclass_operator.
