* libguile/frames.c: Add compile-time assertions on the layout of
`struct scm_vm_frame'.
(RELOC): Parenthesize and type VAL.
* libguile/frames.h (SCM_FRAME_STRUCT): Write in terms of
`SCM_FRAME_DATA_ADDRESS'.
(SCM_FRAME_DATA_ADDRESS): Parenthesize and type FP.
(SCM_FRAME_SET_DYNAMIC_LINK): Write in terms of
`SCM_FRAME_DYNAMIC_LINK'.
* libguile/vm.c (RELOC): Parenthesize and type SCM_P.
* test-suite/tests/asm-to-bytecode.test (native-cpu, native-word-size):
New procedures.
(test-target): When the target is the native CPU, use the native word
size instead of WORD-SIZE.
* libguile/symbols.c (scm_gensym): Make the gensym counter a 128-bit
thread-local, initialized to a random number upon the first call to
`gensym' within a given thread. This counter is rendered as a 22 byte
suffix of mostly base64 digits.
* libguile/threads.h (scm_i_thread): Add a thread-local gensym_counter.
* libguile/threads.c (guilify_self_1): Initialize gensym_counter to NULL.
* module/ice-9/boot-9.scm (syntax-local-binding): New binding.
* module/ice-9/psyntax.scm: Locally define a fluid that holds the
"transformer environment". with-transformer-environment calls a
procedure with the transformer environment, or raises an error if
called outside the extent of a transformer. Bind
transformer-environment in expand-macro.
(resolve-identifier): Backport this helper from master.
(syntax-local-binding): New procedure to return binding information of
a bound identifier (a lexical, macro, a pattern variable, a displaced
lexical, a global, or some other form).
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-macros.texi (Syntax Transformer Helpers): Add docs for
syntax-local-binding, and syntax-source, and move some other
descriptions to this new section.
Based on a patch by Julian Graham <julian@member.fsf.org>
* libguile/values.c, libguile/values.h (scm_c_value_ref): New function.
* doc/ref/api-control.texi (Multiple Values): Add documentation.
* test-suite/standalone/test-scm-values.c: New test program.
* test-suite/standalone/Makefile.am: Add test-scm-values test.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
* test-suite/tests/statprof.test ("statistical sample counts within
expected range"): Throw unresolved when one of A-DATA, B-DATA, and
C-DATA is #f, which means samples were not collected for this one.
* module/language/glil/compile-assembly.scm (scheme-list?): New
predicate, like `list?' but requires that the last cdr must be '(),
not #nil.
(dump-object, dump-constants): Use `list' opcode to create a list only
if it is terminated by '(). If it's terminated by #nil, we must use
the more general `cons' opcode.
* libguile/strings.c (scm_i_substring, scm_i_substring_read_only,
scm_i_substring_shared): When asked to create an empty substring,
return a freshly allocated null string. Previously, an empty
substring needlessly held a reference to the original stringbuf.
* libguile/strings.c (scm_from_stringn): Avoid calling
`u32_conv_from_encoding' on the null string, by using the same
fast-path code used if (encoding == NULL). This is an optimization,
and also avoids any possible encoding errors.
* libguile/strings.c (scm_from_stringn): Always return a freshly
allocated string from scm_from_stringn, even when asked to construct
the null string, in accordance with the R5RS. Previously, we
optimized the null string case by returning a reference to a global
null string object (scm_nullstr).
* test-suite/tests/regexp.test (with-unicode): New macro.
("regexp-quote"): Wrap all `regexp-quote' calls in it. This fixes
tests on machines where the default port encoding is US-ASCII.
* libguile/i18n.c (scm_i_locale_free): Remove.
(smob_locale_free): Define only when USE_GNU_LOCALE_API.
(scm_make_locale)[!USE_GNU_LOCALE_API]: Allocate
`c_locale->locale_name' with `scm_gc_strdup', not `malloc'.
* libguile/tags.h (scm_tc7_array): Allocate a tag for arrays.
* libguile/arrays.h (SCM_I_ARRAYP): Change to use scm_tc7_array. The
previous definition was not externally usable because scm_i_tc16_array
was internal.
(scm_i_print_array): Declare, though internally.
* libguile/arrays.c (scm_i_make_array): Use scm_cell with the tc7
instead of NEWSMOB.
(scm_i_print_array): Make not static.
(SCM_ARRAY_IMPLEMENTATION): Adapt.
(scm_init_arrays): Remove array smob declaration.
* libguile/eq.c (scm_equal_p): Refactor to put the string, pointer, and
bytevector cases in the switch. Add a case for arrays.
* libguile/goops.c: Add <array> declarations.
* libguile/print.c (iprin1): Call scm_i_print_array as needed.
* libguile/evalext.c (scm_self_evaluating_p): Add a case for arrays.
* libguile/load.c (scm_primitive_load): Return the values yielded from
evaluating the last expression in the file.
* test-suite/tests/load.test ("return value of `load'"): Add tests.
