You need these templates for generic code.
In other words, in another templates.
Stop increasing compilation time for no reason.

 2020-11-29 15:35:05 +03:00
Nekotekina 8b6d615aa6 atomic.hpp: remove/deprecate incomplete notify features 
Notification with "phantom value" could be useful in theory.
As an alternative way of sending signal from the notifier.
But current implementation is just useless.
Also fixed slow_mutex (not used anywhere).
 2020-11-26 06:31:36 +03:00
Nekotekina 27097cbcfe atomic.hpp: alter atomic_storage<>::store a bit

Nekotekina 280f5f0b54 atomic.hpp: redefine op::ne to actually mean "not equal"

 2020-11-13 12:40:02 +03:00
Nekotekina 70761a4ef0 atomic.cpp: fix notification bug from few commits before 
Make sure forced notification ignores mask comparison.
Also fix masks provided by smaller types to correct ones.
 2020-11-12 05:01:44 +03:00
Nekotekina 7cd1e767be atomic.cpp: implement some atomic wait operations. 
Instead of plain waiting while equal to some value,
it can be something like less, or greater, or even bitcount.
But it's a draft and untested. Hopefully doesn't break anything.
 2020-11-11 20:46:37 +03:00
Nekotekina c047ab6147 atomic.cpp: waitable atomics got brutally rewritten 
Hashtable increased and flatten, tree-alike extensions removed.
Some things simplified, so it can actually decrease perf a bit.
But most platforms shouldn't be affected.
Removed limit of 56 waiters per pointer.
Real limit now is about 65535.
 2020-11-11 05:35:27 +03:00
Nekotekina 0bd989b118 atomic.cpp: allow waiting on multiple variables simultaneously 
Arbitrary maximum set to 8, but really we need 2, maybe 3.
Added atomic_wait::list object for multi-waiting.
Added atomic_wait::get_unique_tsc just in case.
 2020-11-07 18:18:02 +03:00
Nekotekina 1e45437498 Remove unused atomic with lock bit 2020-11-06 16:48:43 +03:00
Nekotekina 557f0c5a8a atomic.cpp: remove load() from notify functions 
Only compare masks for overlap for second overload (with mask provided).
Explicit "new value" can be provided in new 3-arg overloads.
Also rename atomic_storage_futex -> atomic_wait_engine.
 2020-11-06 04:44:31 +03:00
Nekotekina 5248240e10 atomic.cpp: improvements. 
Reduced static memory amount for waitable atomics.
Allow notifier to skip notifications if wait/notify masks don't overlap.
Improve raw_notify to wake up the thread by its id, add thread_id arg.
Add optional mask argument to notify_one() and notify_all().

Remove vm::reservation_lock from it.
Use lock bits to prevent memory clobbering in GETLLAR.

Improve vm::reservation_op and friends.

 2020-10-28 03:47:41 +03:00
Nekotekina 6806e3d5c7 atomic.cpp: implement notify callback

Callback is set for cpu_thread in order to set wait flag accordingly.
