Cleans up a ton of whitespace in cpu.c (like 100KB!) and improves
readability of some massive decode statements.
Added an optimization for PC-relative loads (pool load) in ROM (since
it's read only and cannot possibily change) that directly emits an
immediate load. This is way faster, specially in MIPS/x86, ARM can be
even faster if we rewrite the immediate load macros to also use a pool.
|
|
Some minor formating too
|
|
This works on both interpreter and dynarec.
Tested in MIPS, ARM and x86, still needs some more testing, some edge
cases can be buggy.

This reverts commit fb7ca09b019248b9a0aba481ea55386f71053d73.
It seems that commit broke rolling in Minish Cap when using the ARM dynarec.

Handle already translated blocks in the ARM asm to speed up indirect
branches (affect some games more than others)
|
|
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.
|
|
Add options to select whether to boot from BIOS (default is no, as it is
now) and whether to use the original bios or the builtin one (default is
auto, which tries to use the official but falls back to the builtin if
not found).

Implements:
- fast-forward (toggle)
- audio-buffer-based frameskip and frame limiting
- color-correction (using the libretro code)
- lcd ghosting (using the libretro code)
- FPS display
- input rebinding
- emulator key rebinding
- scaling (with the old gpsp filters and drowsnug's scaled-nofilter)
- saving and savestates
- game-specific configuration
Not yet implemented:
- cheats
- fast-forward (hold)

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.

This is not really necessary since it can share area with ROM.
Performance impact should be very minimal (haven't noticed it myself)
and could be compensated (even by a positive offset) if we bump the ROM
cache area size.
Tested with several dynarecs.

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.

- Removing RETRO_SYSTEM_MEMORY from retro_get_memory_data/size
since its incompatible for 2 reasons:
1. gba uses at least 2 blocks of memory, which is not supported
2. the way gpsp's memory block are not contiguous (see memory
descriptors)
|
|
- Adds core option to allow battery saves using the libretro api
(retro_get_memory_data/size)
- Initial save size set at 128KB and actual size is automatically
determined internally by gba.
- This will always assume that a save file is supported since save
size or type cannot be determined until gba tries to write to backup memory.
- A 128KB block of memory is used as buffer, similar method to VBA
Next/Beetle GBA workarounds.

[3DS] Fix dynarec prefetch aborts
|
|
Similar fix to https://github.com/libretro/pcsx_rearmed/pull/390. The
Nintendo svcBackdoor can cause stack corruption if an interrupt
happens during it, this uses Luma3DS/Rosalina's svcCustomBackdoor instead.
