* libguile/array-handle.c (scm_array_handle_pos_1):
(scm_array_handle_pos_2): New functions.
* libguile/generalized-arrays.c (scm_c_array_ref_1, scm_c_array_ref_2):
(scm_c_array_set_1_x, scm_c_array_set_2_x): New functions.
(scm_i_array_ref, scm_i_array_set_x): New subr bindings for array-ref
and array-set! that avoid consing for arrays of rank 1 or 2.
* test-suite/tests/arrays.test ("array-set!"): Fix expected exception
for wrong number of indices.
* libguile/array-handle.c (scm_i_register_array_implementation):
(scm_i_array_implementation_for_obj): Add generic array facility,
which will (in a few commits) detangle the array code.
(scm_array_get_handle): Use the generic array facility. Note that
scm_t_array_handle no longer has ref and set function pointers;
instead it has a pointer to the array implementation. It is unlikely
that code out there used these functions, however, as the supported
way was through scm_array_handle_ref/set_x.
(scm_array_handle_pos): Move this function here from arrays.c.
(scm_array_handle_element_type): New function, returns a Scheme value
representing the type of element stored in this array.
* libguile/array-handle.h (scm_t_array_element_type): New enum, for
generically determining the type of an array.
(scm_array_handle_rank):
(scm_array_handle_dims): These are now just #defines.
* libguile/arrays.c:
* libguile/bitvectors.c:
* libguile/bytevectors.c:
* libguile/srfi-4.c:
* libguile/strings.c:
* libguile/vectors.c: Register array implementations for all of these.
* libguile/inline.h: Update for array_handle_ref/set change.
* libguile/deprecated.h: Need to include arrays.h now.
* libguile/array-handle.c:
* libguile/array-handle.h: Move some parts of unif.c and unif.h to these
new files.
* libguile/unif.c:
* libguile/unif.h: Update includers. Since unif.h depends on the array
handle type, we include array-handle.h, which also means that there
will be no difference for our callers.
* libguile/init.c: Call scm_init_array_handle, though it does nothing as
of yet.
* libguile/Makefile.am: Adapt for new files.
