* libguile/tags.h (scm_tc7_with_fluids): Allocate a tc7 for
"with-fluids" objects, which will only live on the dynamic stack (wind
list), not in normal scheme-land.
* libguile/fluids.h (SCM_WITH_FLUIDS_P, SCM_WITH_FLUIDS_LEN)
(SCM_WITH_FLUIDS_NTH_FLUID, SCM_WITH_FLUIDS_NTH_VAL)
(SCM_WITH_FLUIDS_SET_NTH_VAL): Add some accessors.
* libguile/fluids.c (scm_i_make_with_fluids, scm_i_swap_with_fluids):
New internal functions.
(scm_c_with_fluids, scm_c_with_fluid): Push with-fluids objects on the
dynwind list, not winders.
* libguile/dynwind.c (scm_i_dowinds): Add cases for winding and
unwinding with-fluids objects.
* libguile/memoize.h (scm_sym_with_fluids, SCM_M_BEGIN): New public
data.
* libguile/memoize.c (scm_m_with_fluids): Define with-fluids as a
primitive syntax.
(unmemoize): Add with-fluids case.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Add with-fluids cases.
* test-suite/tests/fluids.test
("fluids not modified if nonfluid passed to with-fluids"): Enable a
now-passing test.
* module/ice-9/eval.scm: Add a comment explaining the frequencies of the
various memoized expression types.
(eval): Reorder the cases based the profile.
* libguile/memoize.h (scm_sym_at_dynamic_wind, SCM_M_DYNWIND)
* libguile/memoize.c (memoized_tags, MAKMEMO_DYNWIND)
(scm_m_at_dynamic_wind, unmemoize): Add dynwind as a primitive
expression type.
* libguile/dynwind.c (scm_dynamic_wind): Downgrade to a normal C
function.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Add dynwind support.
* module/ice-9/r4rs.scm: More relevant docs.
(apply): Define in a more regular way.
(dynamic-wind): Add to this file, with docs, dispatching to
@dynamic-wind.
* module/language/tree-il/primitives.scm: Parse @dynamic-wind into a
tree-il dynamic-wind.
* module/system/base/compile.scm (compiled-file-name): Add a comment.
* module/ice-9/boot-9.scm (load): Avoid loading up (system base compile)
just to compute an autocompiled file name. Fixes the issue whereby
guile-tools snarf-check-and-output-texi was inadvertantly loading up
srfi-1, and thereby a stale library, just to see if guile-tools itself
had a compiled version.
Not sure what the right unit test is here, other than vigilance.
* module/language/assembly/compile-bytecode.scm (write-bytecode):
Replace the WRITE-BYTE and GET-ADDR parameters with PORT. New ADDRESS
and EMIT-OPCODE? parameters. Callers updated.
[write-byte, get-addr]: New procedures.
Adjust to write to PORT.
(compile-bytecode): Update accordingly.
* test-suite/tests/asm-to-bytecode.test (munge-bytecode): Return a
bytevector instead of a u8vector.
(comp-test): Deal with bytevectors.
* module/language/tree-il/compile-glil.scm (flatten): Push a handler
value even in the inline-handler case, to make prompt's interface more
uniform, and also to correspond to the existing VM implementation.
* module/language/tree-il/analyze.scm (graph-reachable-nodes): Add
REACHABLE argument. Update to use vhash instead of alists or lists.
(graph-reachable-nodes*): Adjust accordingly.
(partition*): New function.
(unused-toplevel-analysis): Adjust to use vhash instead of alists or
lists.
* module/language/tree-il/primitives.scm (define-primitive-expander):
Allow quoted datums. Allow all self-evaluating expressions to be
constants.
(prompt, control): Add primitive expanders to turn these into @prompt
and @control.
* module/ice-9/control.scm: New module, for delimited continuation
operators.
* module/Makefile.am: Add.
* module/language/tree-il/analyze.scm (analyze-lexicals): Add cases for
<prompt>, <dynamic-wind>, and <control>. If a continuation is not
referenced in the body of a prompt handler, mark the prompt as
escape-only.
* module/language/tree-il/inline.scm (inline!): Inline the handler of a
prompt if it is a simple lambda.
* module/language/tree-il/primitives.scm: Resolve calls to dynamic-wind
to <dynamic-wind>, thereby inlining the dynwind to VM ops, and
allowing inline allocation of the body thunk.
* libguile/foreign.h:
* libguile/foreign.c (scm_foreign_set_finalizer_x): New function, for a
limited form of finalization (like `free').
(scm_alignof, scm_sizeof, parse_ffi_type, fill_ffi_type): For the
purposes of make-foreign-function, treat '* (the asterisk symbol) as a
pointer.
* module/system/foreign.scm: Export foreign-set-finalizer!.
* module/statprof.scm (get-call-data): For closures, get call data by
the program's objcode.
(statprof-start, statprof-stop): Fix bug in which all statprof runs
were enabling the apply hook regardless of the setting of
#:count-calls?. The result was distorted timings, where procedure
calls were unfairly penalized.
(procedure=?): Streamline.
* module/language/tree-il/compile-glil.scm (*primcall-ops*):
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Actually resolve calls to
`variable-bound?' to the opcode that we have for it.
* libguile/Makefile.am (AM_CPPFLAGS): Move LIBFFI_CFLAGS here (from
AM_CFLAGS), allowing snarfing to work.
* libguile/foreign.h (scm_make_foreign_function): New public function.
* libguile/foreign.c: Flesh out an implementation of foreign functions.
(scm_take_foreign_pointer): Bugfix for the case in which we have a
finalizer.
* module/system/foreign.scm: Export `make-foreign-function'.
* libguile/foreign.h:
* libguile/foreign.c (scm_foreign_ref, scm_foreign_set_x): Remove all
bits about offsets and aliasing; bytevectors are much better at that.
(scm_foreign_to_bytevector, scm_bytevector_to_foreign): New functions
for getting at the bytes of a memory region.
* module/system/foreign.scm (foreign->bytevector, bytevector->foreign):
Export these.
* libguile/foreign.h:
* libguile/init.c: Change so that init just registers an extension,
later called by foreign.scm.
* libguile/foreign.c (scm_init_foreign): Define constants for the
various foreign types.
* module/Makefile.am:
* module/system/foreign.scm: New module, for the foreign function
interface.
* module/scripts/snarf-check-and-output-texi.scm
(process-multiline-directive): Be more accepting of source location
markers in the preprocessed source, by adding a couple cases in which
they can appear. Not foolproof, but it does adapt to what new GCCs are
putting out (e.g. cpp (GCC) 4.4.2 20091222 (Red Hat 4.4.2-20)).
* libguile/posix.h:
* libguile/posix.c (scm_utime): Add optional nanosecond arguments. This
is an incompatible change on the C level, but it's unlikely people are
using this POSIX wrapper function, because they would just use the
POSIX function directly. Hopefully, anyway.
* module/system/base/compile.scm (call-with-output-file/atomic):
Propagate source timestamps to targets with nanosecond precision, if
available. Fixes build on systems with ext4 filesystems.
* libguile/filesys.c (scm_stat2scm):
* module/ice-9/posix.scm (stat:atimensec, stat:mtimensec)
(stat:ctimensec): Add three new elements to Scheme stat structures,
for nanosecond-level timestamps.
* configure.ac: Add checks for utimensat, and for nanosecond fields in
struct stat. We should switch to using Gnulib things for these,
though.
* doc/ref/posix.texi (File System): Add documentation for utime's
additional arguments, and nanosecond stat timestamp accessors.
* module/statprof.scm: Use VM modules, instead of using @ hacks.
(statprof): New public export, a functional interface to the profiler.
(profile-signal-handler, count-call, statprof-start, statprof-stop):
Fix call counting with the VM.
(statprof-call-data->stats): Hack around a case in which a call could
be sampled but not counted, if you get my drift.
(procedure=?): Update for current API.
(with-statprof): Use `statprof'.
* module/system/repl/command.scm (profile): Use the `statprof'
procedural interface.
* module/ice-9/syncase.scm: Export datum->syntax-object and
syntax-object->datum as aliases of datum->syntax and syntax->datum.
Thanks to Daniel Llorens del Río for the suggestion.
* module/system/vm/trace.scm (vm-trace): Change to just export the one
procedure, vm-trace. This way it's threadsafe and more robust. Also
refactor to not print any of Guile's internal bits. Hopefully Neil
will be happier :)
* module/system/repl/command.scm (option): Adapt to removal of
vm-trace-on! and vm-trace-off!, as those are unlikely to DTRT.
* module/system/vm/program.scm (program-arguments-alist): Rename from
program-arguments, a name shadowed by features.c
(arglist->arguments-alist, arity->arguments-alist)
(arguments-alist->lambda-list, program-lambda-list, write-program):
Adapt callers.
* module/system/vm/frame.scm (frame-lookup-binding): Return #f if the
binding is not found, not an error.
(frame-binding-set!, frame-binding-ref): Adapt to error appropriately.
(frame-arguments): Dispatch to frame-call-representation.
(frame-call-representation): Refactor a bit.
* module/ice-9/session.scm (procedure-arguments): Adapt to
program-arguments name change.
* module/texinfo/reflection.scm (get-proc-args): Refactor to actually
work with VM procedures.
* libguile/arrays.h:
* libguile/arrays.c (scm_from_contiguous_array): New public function,
like scm_from_contiguous_typed_array but for arrays of generic Scheme
values.
* libguile/vm-i-scheme.c (make-struct): Sync regs before making the
struct, so if we get a GC the regs are on the heap.
(make-array): New instruction, makes an generic (untyped) Scheme
array.
* module/language/glil/compile-assembly.scm (dump-object): Correctly
compile arrays.
* module/ice-9/boot-9.scm (export, re-export): Evaluate at compile-time
in addition to load/eval.
* test-suite/tests/tree-il.test ("warnings")["unused-toplevel"]("unused
but define-public"): Remove throw to `unresolved'.
