Prevents a problem where with-exception-handler isn't defined yet by the
time the first finalizer gets kicked off (it's a file port, probably one
that is closed already...)
* libguile/finalizers.h:
* libguile/init.c (scm_i_init_guile):
* libguile/finalizers.c (queue_finalizer_async): Mark maybe-unused.

finished initializing.

(scm_i_add_smob_finalizer):
(scm_i_add_port_finalizer):
(scm_i_add_pointer_finalizer):
(scm_i_add_finalizer): Use new helpers.

(spawn_finalizer_thread):
(scm_i_finalizer_pre_fork):
(scm_set_automatic_finalization_enabled):
(scm_init_finalizers):
(scm_init_finalizer_thread): Use Whippet API.
* libguile/finalizers.h (scm_i_set_finalizer, scm_i_add_resuscitator):
Remove.
Instead of storing keep-alive edges in weak tables, just add extra
fields on pointer objects.
* libguile/foreign.c (make_pointer, pointer_extra_word_count)
(set_pointer_extra_word, make_pointer_0, make_pointer_1, make_pointer_3)
(attach_finalizer): New helpers.
(scm_make_pointer): Never attach finalizers on the null pointer object.
(scm_from_pointer): Likewise.
(scm_bytevector_to_pointer, scm_procedure_to_pointer): Store keep-alive
links in extra words.
(scm_init_foreign, scm_register_foreign): Rework init for null, free,
and ffi_closure_free pointers.
These tables will be implemented differently after Whippet.
* libguile/weak-set.c (do_vacuum_weak_set, vacuum_all_weak_sets):
Remove.
(scm_c_make_weak_set, scm_init_weak_set): Don't keep a table of all weak
sets.

Remove.
(scm_c_make_weak_table, scm_init_weak_table): No table of all tables.
* libguile/atomics-internal.h (scm_atomic_set_bits): New routine.
* libguile/smob.c (scm_i_finalize_smob): Use atomics to clear the first
word instead of the GC alloc lock.
(finalize_smob): Implement as shim.
We're on a new version series, let's remove deprecated things. Also
reduces the amount of work we need to do in adapting to a new GC,
notably for bignums.
* configure.ac (--disable-tmpnam): Remove flag, tmpnam is gone.
* doc/ref/posix.texi (File System): Remove tmpnam docs.
* libguile/bitvectors.c (scm_bitvector_to_list): Remove deprecated
branch treating arrays as bitvectors.
* libguile/deprecated.c: Remove all deprecated code. Whee!
* libguile/deprecated.h: Remove deprecated decls.
* libguile/posix.c (scm_tmpnam): Remove.
* libguile/struct.c (scm_is_valid_vtable_layout): Remove support for 'r'
fields.
* libguile/vectors.c (scm_vector_copy_partial, scm_vector_to_list)
(scm_vector_move_left_x, scm_vector_move_right_x): Remove generalized
array cases.
* test-suite/tests/vectors.test ("vector->list"): Remove shared array
test
Whippet may add a shrink interface, if it is needed.
* doc/ref/api-memory.texi (Memory Blocks): Remove some 1.8 references.
Remove discussion of scm_gc_malloc. Remove discussion of scm_gc_free.
* libguile/gc.h:
* libguile/gc-malloc.c (scm_gc_malloc): Remove.
* libguile/srfi-14.c (char_ranges_insert, char_ranges_delete): New
helpers.
(scm_i_charset_set, scm_i_charset_set_range, scm_i_charset_unset): Use
the new helpers.
* module/ice-9/atomic.scm: Don't add-interesting-primitive! here.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Instead, import atomics here and
register the primitives as usual. This will let atomics be used earlier
in the boot graph.
* libguile/r6rs-ports.c (grow_byte_buffer, shrink_byte_buffer): New
helpers.
* libguile/r6rs-ports.c (bytevector_output_port_buffer_grow):
(bytevector_output_port_procedure): Use new helpers.

(scm_gc_malloc): Dispatch to scm_inline_gc_malloc.
(scm_gc_calloc): Dispatch to scm_gc_malloc.
(scm_gc_realloc): Mark for removal. The issue is that the realloc'd
object should have the same kind. We could add Whippet API but it would
be nice to not do that.
* libguile/jit.c (compile_allocate_words_immediate):
(compile_allocate_words_immediate_slow):
(compile_allocate_pointerless_words_immediate):
(compile_allocate_pointerless_words_immediate_slow): Update for new API.
* api/gc-api.h (gc_allocate_small_fast_freelist):
* src/bdw.c (allocate_small): Clear freelist link, so the object is
completely zeroed. In some cases the embedder / compiler / JIT will be
able to elide this write.
* libguile/gc-malloc.c: Trim set of includes.
(do_gc_malloc_atomic): Remove.
(scm_gc_malloc_pointerless): Call scm_inline_gc_malloc_pointerless.
(scm_gc_strndup): Call scm_gc_malloc_pointerless.
* libguile/gc.h:
* libguile/gc.c (scm_gc_after_nonlocal_exit): Give it a scm_thread
argument, and cause GC with whippet API.
(scm_init_gc): Set alloc failure handler using Whippet API instead of
BDW.
(scm_oom_fn): Add heap argumnet.
* libguile/eval.c (eval):
* libguile/exceptions.c (scm_c_with_exception_handler):
* libguile/vm.c (scm_call_n): Adapt.
Headed towards a 4.0. The binary format will change slightly but
incompatibly (e.g. renumbering of intrinsics). Having a new GC is
enough of a change to warrant a minor version bump, and it's been 5
years so why not go major.
* GUILE-VERSION (GUILE_EFFECTIVE_VERSION): Bump to 4.0.
(GUILE_MICRO_VERSION, GUILE_MINOR_VERSION): Bump to 3.9.0.
(LIBGUILE_INTERFACE_CURRENT, LIBGUILE_INTERFACE_AGE): Reset.
* meta/guile-4.0.pc.in:
* meta/guile-4.0-uninstalled.pc.in: Rename from guile-3.0.
* .gitignore: Ignore pkg-config files with 4.0 effective version.
* README: Update slightly.
* doc/ref/api-evaluation.texi (Load Paths):
* doc/ref/api-options.texi (Build Config):
* doc/ref/guile-invoke.texi (Environment Variables):
* doc/ref/history.texi (A Timeline of Selected Guile Releases):
* doc/ref/libguile-parallel.texi (Parallel Installations):
* doc/ref/srfi-modules.texi (SRFI-0): Update references to stable
version in paths.
* module/system/vm/assembler.scm (*bytecode-minor-version*):
* libguile/loader.h (SCM_OBJCODE_MAJOR_VERSION):
(SCM_OBJCODE_MINIMUM_MINOR_VERSION):
(SCM_OBJCODE_MINOR_VERSION): Use the same major objcode version for now
but bump the minor to 99.
* meta/guile.m4 (GUILE_PKG, GUILE_PROGS): Check for Guile 4.0.
* module/ice-9/boot-9.scm (%cond-expand-features): Add new cond-expand
features.
* libguile/scm.h (scm_tc7_thread): Give threads their own tc7.
* libguile/threads.h (struct scm_thread): Add a tag, so that struct
thread can be a SCM directly. Add a struct gc_mutator* member.
(scm_thread_handle): New inline function.
(SCM_I_IS_THREAD, SCM_I_THREAD_DATA, SCM_VALIDATE_THREAD): Update to use
tc7 instead of SMOB tags.
* libguile/continuations.c (scm_i_with_continuation_barrier)
* libguile/finalizers.c (queue_finalizer_async)
* libguile/jit.c (compile_current_thread)
* libguile/threads.c (block_self, guilify_self_2)
(lock_mutex, unlock_mutex, timed_wait scm_current_thread)
(scm_all_threads)
* libguile/vm-engine.c (current-thread): Use scm_thread_handle instead
of thread->handle.
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (class_thread, scm_class_of, scm_sys_goops_early_init)
* libguile/print.c (iprin1)
* module/language/cps/compile-bytecode.scm (compile-function)
* module/oop/goops.scm (<thread>)
* module/system/base/types.scm (cell->object)
* module/system/base/types/internal.scm (heap-tags)
* module/system/vm/assembler.scm: (emit-thread?): Adapt to
scm_tc7_thread.
* libguile/gc-internal.h: Move init functions that take "struct
gc_stack_addr" here, so that internal Whippet uses don't cause Whippet
to be added to public headers.
* libguile/gc.c (scm_storage_prehistory): Take struct gc_stack_addr as
arg, and pass to gc_init. Return a mutator pointer.
* libguile/init.c (scm_i_init_guile): Pass mutator and stack base to GC
and thread init routines.
* libguile/threads.c (scm_trace_dynstack, scm_trace_thread)
(scm_trace_thread_mutator_roots): New infra for marking threads in terms
of Whippet API.
* libguile/threads.c (guilify_self_1): Since we don't use a separate GC
kind for threads any more, and thread marking is keyed off
gc_mutator_set_roots, we can avoid some of the gnarly synchronization.
(on_thread_exit): Arrange to gc_finish_for_thread.
(scm_i_init_thread_for_guile): Use gc_init_for_thread.
(init_main_thread, with_guile, scm_i_with_guile): Use Whippet API.
(scm_threads_prehistory): Take main-thread mutator and the stack base as
arguments.
* libguile/vm.c (scm_trace_vm): Rework in terms of Whippet API.

the current mutator's SCM thread object.
* libguile/trace.h: New file, to declare implementations of trace
routines.
* libguile/Makefile.am (noinst_HEADERS): Add trace.h.
