Savestates Support For PS3 Emulation (#10478) 2022-07-04 16:02:17 +03:00
Megamouse 2821eb7397 Remove some lwmutex log spam 
I don't know if there's a reason for the warning message.
So I'll just change it and see how many developers throw insults at me :)

Eladash 8c3a4c260e Bugfix of sys_lwmutex_destroy 2021-08-04 09:03:17 +03:00
Nekotekina 160b131de3 types.hpp: implement smin, smax, amin, amax 
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.

Fix operators == and <=> for synthesized rel-ops.

Atomic waiting refactoring (#9208) 
* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
