2021-03-26Move OAM RAM to stubs alsoDavid Guillen Fandos
Makes accesses more efficient for MIPS. Make accesses also fast for palette reads.
2021-03-26Move OAM update flag to a registerDavid Guillen Fandos
Fix a small bug in MIPS dynarec that affects non -G0 targets
2021-03-23Move caches to stub files to get around gcc 10David Guillen Fandos
Seems that using the __atribute__ magic for sections is not the best way of doing this, since it injects some default atributtes that collide with the user defined ones. Using assembly is far easier in this case. Reworked definitions a bit to make it easier to import from assembly. Also wrapped stuff around macros for easy and less verbose implementation of the symbol prefix issue.
2021-03-23Make ewram memory linealDavid Guillen Fandos
This saves a few cycles in MIPS and simplifies a bit the core. Removed the write map, only affects interpreter performance very minimally. Rewired ARM and x86 handlers to support direct access to I/EWRAM (and VRAM on ARM) to compensate. Overall performance is slightly better but code is cleaner and allows for further improvements in the dynarecs.

Added a more thorough cache cleanup for reset/mode-change too. Fixed the mmap initialization that ends up leaking memory. Minor x86 asm fixes for Android.
2021-03-16Move a few more registers to contextDavid Guillen Fandos
This gets rid of some more absolute addrs in the MIPS dynarec. Tested on several platforms, we should be good.
2021-03-15Move palettes around to simplify MIPS dynarecDavid Guillen Fandos
Will move also OAM structures to gain a few cycles per load/store. Loads can also be optimized for an extra instruction per access.
2021-03-08Remove libcoDavid Guillen Fandos
This removes libco and all the usages of it (+pthreads). Rewired all dynarecs and interpreter to return after every frame so that libretro can process events. This required to make dynarec re-entrant. Dynarecs were updated to check for new frame on every update (IRQ, cycle exhaustion, I/O write, etc). The performance impact of doing so should be minimal (and definitely outweight the libco gains). While at it, fixed small issues to get a bit more perf: arm dynarec was not idling correctly, mips was using stack when not needed, etc. Tested on PSP (mips), OGA (armv7), Linux (x86 and interpreter). Not tested on Android though.
