* | Fix atomics compilation on clang...* libguile/atomics-internal.h (scm_atomic_subtract_uint32):
(scm_atomic_compare_and_swap_uint32, scm_atomic_set_pointer):
(scm_atomic_ref_pointer, scm_atomic_set_scm):
(scm_atomic_ref_scm, scm_atomic_swap_scm):
(scm_atomic_compare_and_swap_scm): Use C11 atomic types if we have
loaded C11 stdatomic.h.

* | Refine check for when atomics are available....* configure.ac:
* libguile/atomics-internal.h: Use HAVE_STDATOMIC_H to know when to use
atomics.
| Andy Wingo | 2016-12-06 | 1 | -5/+3 |
* | Use atomics for async interrupts...* libguile/__scm.h (SCM_TICK): Always define as scm_async_tick().
* libguile/error.c (scm_syserror, scm_syserror_msg):
* libguile/fports.c (fport_read, fport_write):
* libguile/_scm.h (SCM_SYSCALL): Replace SCM_ASYNC_TICK with
scm_async_tick ().
(SCM_ASYNC_TICK, SCM_ASYNC_TICK_WITH_CODE)
(SCM_ASYNC_TICK_WITH_GUARD_CODE): Remove internal definitions. We
inline into vm-engine.c, the only place where it matters.
* libguile/async.h:
* libguile/async.c (scm_async_tick, scm_i_setup_sleep):
(scm_i_reset_sleep, scm_system_async_mark_for_thread):
* libguile/threads.h (struct scm_thread_wake_data):
* libguile/threads.h (scm_i_thread):
* libguile/threads.c (block_self, guilify_self_1, scm_std_select):
Rewrite to use sequentially-consistent atomic references.
* libguile/atomics-internal.h (scm_atomic_set_pointer):
(scm_atomic_ref_pointer): New definitions.
* libguile/finalizers.c (queue_finalizer_async): We can allocate, so
just use scm_system_async_mark_for_thread instead of the set-cdr!
shenanigans.
* libguile/scmsigs.c (take_signal):
* libguile/gc.c (queue_after_gc_hook): Adapt to new asyncs mechanism.
Can't allocate but we're just manipulating the current thread when no
other threads are running so we should be good.
* libguile/vm-engine.c (VM_HANDLE_INTERRUPTS): Inline the async_tick
business.

* | Add atomic boxes...* doc/ref/api-scheduling.texi (Atomics): New manual section.
* libguile.h: Include atomic.h.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(DOT_X_FILES, DOT_DOC_FILES, modinclude_HEADERS): Add atomic.
* libguile/atomic.c:
* libguile/atomic.h: New files.
* libguile/atomics-internal.h (scm_atomic_set_scm, scm_atomic_ref_scm)
(scm_atomic_swap_scm, scm_atomic_compare_and_swap_scm): New
facilities.
* libguile/goops.c (class_atomic_box, scm_sys_goops_early_init): Add
support for <atomic-box>. Remove duplicate <keyword> fetch.
* libguile/init.c (scm_i_init_guile): Call scm_register_atomic_box.
* libguile/print.c (iprin1): Add atomic box case.
* libguile/tags.h (scm_tc7_atomic_box): New tag.
* libguile/validate.h (SCM_VALIDATE_ATOMIC_BOX): New macro.
* module/Makefile.am (SOURCES): Add ice-9/atomic.scm.
* module/ice-9/atomic.scm: New file.
* module/oop/goops.scm (<atomic-box>): New var.

* libguile/atomics-internal.h: New file.
* libguile/ports-internal.h (refcount): New member.
* libguile/ports.c (release_port, scm_dynwind_acquire_port): New
facility for acquiring a port within a dynwind.
(scm_port_poll, scm_i_read_bytes, scm_setvbuf, scm_end_input)
(scm_i_write_bytes, scm_char_ready_p, scm_seek)
(scm_truncate_file, trampoline_to_c_read)
(trampoline_to_c_write): Acquire port.
(scm_c_make_port_with_encoding): Init refcount to 1.
