* libguile/array-map.c: (scm_array_index_map_x): bail out if any one of the
axes is empty.
* test-suite/tests/ramap.test: add tests for empty array-case of
array-index-map!. The 'f64 case with not-last emtpy axis is broken in 2.0.9.
* libguile/generalized-arrays.c (scm_is_array, scm_is_typed_array): In
preparation for removing the registry of array implementations, remove
a couple uss of scm_i_array_implementation_for_obj.
* libguile/tags.h (SCM_TYP7S, SCM_HAS_TYP7S): Remove these, as we no
longer do the differs-by-one-bit thing for vectors and weak vectors.
* libguile/vectors.h (SCM_I_IS_VECTOR): Use SCM_HAS_TYP7.
(SCM_I_IS_NONWEAK_VECTOR): Remove.
* libguile/vm-engine.c (vector-length, vector-ref, vector-set!)
(vector-ref/immediate, vector-set!/immediate): We can inline these
instructions completely now.
* libguile/vm.c (vm_error_not_a_vector, vm_error_out_of_range): New
error conditions.
* libguile/vectors.c (scm_is_vector): Deprecate use on weak vectors and
arrays.
(scm_is_simple_vector): Deprecate use on weak vectors.
(scm_vector_length, scm_c_vector_ref, scm_c_vector_set_x): Deprecate
use on arrays.
* libguile/sort.c: Adapt to check explicitly for arrays.
* libguile/vectors.c (scm_vector_length, scm_c_vector_ref):
(scm_c_vector_set_x): Deprecate the use of vector-length, vector-ref,
and vector-set! as primitive generics.
This commit also renames uniform-vector-element-type-code to
array-type-code.

Deprecate. This interface lacked both generality and specificity.
The general replacement is array-length, array-ref, and friends on the
scheme side, or the array handle interface on the C side. On the
specific side of things, there are the specific bytevector, srfi-4,
and bitvector interfaces.
* test-suite/tests/arrays.test:
* test-suite/tests/bitvectors.test:
* test-suite/tests/ports.test:
* test-suite/tests/srfi-4.test: Update to use array interfaces.
* doc/ref/api-foreign.texi (Void Pointers and Byte Access):
* doc/ref/srfi-modules.texi (SRFI-4): Update.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): In the raw element
accessors (e.g scm_u32vector_writable_elements), only permit
bytevectors, as the constructors will only make bytevectors. This
harmonizes with the Scheme interfaces as well, which expect packed
bytevectors.
(scm_make_srfi_4_vector): Knowing that the new value is a bytevector
with base 0 and inc 1, simplify initialization.
* libguile/hashtab.c (scm_make_doubly_weak_hash_table): Make 'size'
argument optional, like the weak hash table constructors.
* doc/ref/api-memory.texi (Weak hash tables): Document that 'size'
argument is optional for the weak hash table constructors.
* libguile/weak-vectors.h:
* libguile/weak-vectors.c (scm_is_weak_vector, scm_c_weak_vector_length):
(scm_c_weak_vector_ref, scm_c_weak_vector_set_x): New interfaces for
dealing with weak vectors from C.
(scm_weak_vector_length, scm_weak_vector_ref, scm_weak_vector_set_x):
New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.

procedures on weak vectors.

* libguile/array-map.c
- rafill, ramap, rafe, racp: object from SCM_I_ARRAY_V always
has base 0, lbnd 0 and inc 1; make use of this.
* libguile/arrays.c
- array_handle_ref, array_handle_set: idem.
- array_get_handle: sanity check.
* libguile/generalized-vectors.c
- scm_c_generalized_vector_ref, scm_c_generalized_vector_set_x:
pos should be base when idx is lbnd. Furthermore, pos should be signed and
have its overflow checked; do this by handling the job to
scm_c_array_ref_1, scm_c_array_set_1_x.
* libguile/generalized-vectors.h
- fix prototypes.
* libguile/arrays.c (scm_transpose_array)
- Use scm_c_array_rank(), which contains an implicit is_array test.
- Handle the rank 0 case.
* test-suite/tests/arrays.test
- Add test for rank 0 case.
- Add failure test for non array argument.
* libguile/array-map.c (scm_ra_matchp): Refactor logic a bit.
(array_index_map_1, array_index_map_n)
(scm_array_index_map_x): Internally refactor array-index-map! to use
separate implementations for rank 1 versus rank >1 arrays.
* libguile/uniform.c (scm_is_uniform_vector): Replace
scm_is_generalized_vector and scm_generalized_vector_get_handle by
scm_is_array and manual rank check.
(scm_c_uniform_vector_length): Use scm_c_array_length.
(scm_c_uniform_vector_ref): Use scm_c_array_ref_1.
(scm_c_uniform_vector_set): Use scm_c_array_set_1_x.
(scm_uniform_vector_writable_elements): Use scm_array_get_handle, and
assert that the rank is 1.
* test-suite/test/arrays.test: Rename the uniform-vector-ref block to
uniform-vector. Exercise uniform-vector-length and shared arrays
remaining uniform.
Modifications by Andy Wingo <wingo@pobox.com>.
* libguile/vm.c (vm_increase_sp): New interface, to increase the SP to
some new level, possibly expanding the stack.
(vm_push_sp, vm_restore_sp): Intefaces to vm_increase_sp.
(vm_return_to_continuation): Don't throw an error if there's not
enough space; instead, expand.
(vm_reinstate_partial_continuation): Use the new helper.
(return_unused_stack_to_os): Avoid off-by-one error (sp points to
valid memory.)
(scm_call_n): Never write beyond the sp.
* module/language/cps.scm ($callk): New expression type, for calls to
known labels. Part of "low CPS".
* module/language/cps/arities.scm:
* module/language/cps/closure-conversion.scm:
* module/language/cps/compile-bytecode.scm:
* module/language/cps/dce.scm:

* module/language/cps/slot-allocation.scm:
* module/language/cps/verify.scm: Adapt call sites.
* libguile/vm-engine.c (call-label, tail-call-label): New instructions.
Renumber the rest; this is an ABI change.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION):
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* doc/ref/compiler.texi (CPS in Guile): Document $callk.
* libguile/gc.c: Remove code that would try to run GC more frequently as
the process image size was increasing. Before, it was often the case
that the heap was the main component of image size, but with
expandable stacks and statically allocated data that is no longer
true. Also, once scm_gc_register_allocation was incorporated, we
don't need to be so conservative any more. It seems this code was
simply causing too many gc's to run. Removing it improves some
micro-benchmarks; time will tell.
* libguile/bdw-gc.h: Remove a needless compatibility hack.
* libguile/gc-inline.h: New file, implementing thread-local freelists
providing faster allocation if we already have a scm_i_thread*
pointer. Based on gc_inline.h from libgc.
* libguile/threads.h (scm_i_thread): Add freelists here.
* libguile/threads.c (guilify_self_1, guilify_self_2): Initialize
freelists.
* libguile/vm.c: Include gc-inline.h.
* libguile/vm-engine.c: Rename current_thread to thread. Use
scm_inline_cons instead of scm_cons, scm_inline_cell instead of
scm_cell, and scm_inline_words instead of words.
* libguile/vm.h (struct scm_vm): Reorder fields. Add "sp_max_since_gc"
field.
* libguile/vm-engine.c (ALLOC_FRAME, RESET_FRAME):
* libguile/vm.c (vm_return_to_continuation)
(vm_reinstate_partial_continuation, scm_call_n): In places where we
could increase the stack height, update sp_max_since_gc.
(vm_expand_stack): Relocate sp_max_since_gc on expansion.
(scm_bootstrap_vm): Record the page size using gnulib's getpagesize.
(return_unused_stack_to_os): New routine, run when marking stacks.
