Nekotekina c30cdfb3a7 atomic.cpp: merge more atomic variables for simplicity 
Compress 16-bit ref counter and two 48+64 bit slot allocators.
This allowed to remove some weird unnecessary logic paths.
Adjust hashtable size to keep it the same.
 2020-11-12 03:39:05 +03:00
Nekotekina 350b704cd7 atomic.cpp: combine two atomics (ref ctr and wait ptr) 
Should fit into cache line perfectly.
Also makes ptr check more robust.
 2020-11-12 01:06:12 +03:00
Nekotekina ad013d59f4 atomic.cpp: don't load actual memory on empty mask 
It's not an optimization. It just allows some tricks safely.
 2020-11-11 23:59:09 +03:00
Nekotekina d391133524 atomic.cpp: minor notification improvement 
Check mask before locking the reference.
Can help to not bother non-eligible waiters.

 2020-11-11 22:43:13 +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 d1ee7c651f Make memory locking optional (mlock, VirtualLock). 
Fix desired locking operation (to fix "sudo" memory).
It was discovered that some systems have outdated configuration.
With too tight limit, it's almost impossible to lock anything in memory.
 2020-11-10 06:05:37 +03:00
Nekotekina dcbe8ef5f4 Import VirtualAlloc2 if available (Win10+) 
Import MapViewOfFile3 as well.

Nekotekina 0bd989b118 atomic.cpp: allow waiting on multiple variables simultaneously

Nekotekina 6811ec562c Use parentheses for new T() syntax 
MSVC keeps being dumb...
 2019-08-27 03:50:15 +03:00
Nekotekina 8517ccfdfa Add new typemap for always existing objects 
Not to be confused with singletons or global variables.
 2019-08-22 02:13:39 +03:00
Nekotekina 11a43e25d7 typeindices.hpp - start index from 0 
Starting it from 1 makes it more error-prone to use.
 2019-08-17 23:40:51 +03:00
Nekotekina 4df1c16099 Implement stx::typeinfo_v (util/typeindices.hpp) 
Move and generalize logic from typemap.h
 2019-08-14 21:04:25 +03:00
Nekotekina 4f22559ff0 Remove dumb overloads of atomic_op, fetch_op 
And lf_queue::apply.
Fix inlining problem by passing F by value.
 2019-08-14 20:28:34 +03:00
Nekotekina 5bd17a44c9 Add fallback implementation for waitable atomics

 2019-07-29 21:55:59 +03:00
Nekotekina e1db6cef6f Remove ignored bits in waitable atomics 
It was not implemented correctly.
