* libguile/bytevectors.h (scm_i_native_endianness): Allow the VM to use
scm_i_native_endianness, but still keep it marked as internal.
* libguile/bytevectors.c: Adjust to use scm_i_native_endianness instead
of native_endianness. Define it at bootstrap time.
* libguile/bytevectors.c (scm_tc16_bytevector, print_bytevector,
bytevector_equal_p, free_bytevector): Don't use the snarfing macros.
(scm_bootstrap_bytevectors): New.
(scm_init_bytevectors): No longer initialize SCM_NULL_BYTEVECTOR,
which is done by `scm_bootstrap_bytevectors ()'.
* libguile/bytevectors.h (scm_bootstrap_bytevectors): New declaration.
(scm_init_bytevectors): Made internal. This can be done because we
explicitly register it with `scm_c_register_extension ()' in
`scm_bootstrap_bytevectors ()'.
* libguile/init.c (scm_i_init_guile): Call `scm_bootstrap_bytevectors ()'.
This is so that expressions like "(generalized-vector-length #vu8())"
work even when `(rnrs bytevector)' hasn't been loaded.
As a side effect, this allows compilation of literal bytevectors
("#vu8(...)"), which gets done by the generic array handling
of the GLIL->assembly compiler.
* doc/ref/api-compound.texi (Generalized Vectors): Mention bytevectors.
(Arrays, Array Syntax): Likewise.
* doc/ref/api-data.texi (Bytevectors as Generalized Vectors): New node.
* libguile/bytevectors.c (scm_i_bytevector_generalized_set_x): New.
* libguile/bytevectors.h (scm_i_bytevector_generalized_set_x): New
declaration.
* libguile/srfi-4.c (scm_i_generalized_vector_type,
scm_array_handle_uniform_element_size,
scm_array_handle_uniform_writable_elements): Add support for
bytevectors.
* libguile/unif.c (type_creator_table): Add `vu8'.
(bytevector_ref, bytevector_set): New functions.
(memoize_ref, memoize_set): Add support for bytevectors.
* libguile/vectors.c (scm_is_generalized_vector,
scm_c_generalized_vector_length, scm_c_generalized_vector_ref,
scm_c_generalized_vector_set_x): Add support for bytevectors.
* test-suite/tests/bytevectors.test ("Generalized Vectors"): New test
set.
* libguile/bytevectors.c (bytevector_equal_p): New function.
* test-suite/tests/bytevectors.test ("2.3 Operations on Bytes and
Octets")["equal?"]: New test.
* module/rnrs/bytevector.scm (rnrs):
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): New function.
* libguile/unif.h:
* libguile/unif.c (scm_from_contiguous_typed_array): New function.
* libguile/vm-i-loader.c (load-array): New instruction, for loading byte
data into uniform vectors. Currently it copies out the data, though in
the future we could avoid that.
* module/language/assembly.scm (align-code): New exported function,
aligns code on some boundary.
(align-program): Use align-code.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Support
the load-array instruction.
* module/language/glil/compile-assembly.scm (dump-object): Dump uniform
arrays. Neat :)
