2021-05-17Add ROM mirroring and fix mult. cycle countDavid Guillen Fandos
This should correct some minor issues in some games.
2021-05-17Fix ARM dynarec unaligned 32 bit loadsDavid Guillen Fandos
This might make a handful games slightly slower (but on the upper side they work now instead of crashing or restarting). Also while at it, fix some minor stuff in arm stubs for speed.

2021-05-07Small optimization (~2-4%) and whitespace cleanup!David Guillen Fandos
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.
2021-05-05Fix aligned32 reads in interpreter modeDavid Guillen Fandos
An address check was missing to read aligned 32 (stm/ldm) data from high mem areas (0xX0000000). This fixes SM4 EU that for some reason has some weird memory access (perhaps a bug?)
2021-05-05Fix small buf and add cheat error messagesDavid Guillen Fandos
Some minor formating too
2021-05-05Adding Code Breaker cheat supportDavid Guillen Fandos
This works on both interpreter and dynarec. Tested in MIPS, ARM and x86, still needs some more testing, some edge cases can be buggy.

2021-04-27Fix Vita port and likely some Linux/Android hidden issuesDavid Guillen Fandos
Using an invalid SP makes Vita crash (for an unkown reason) and makes things like C signal handlers crash (luckily Retroarch doesn't use them). It is also a violation of the ABI and not a great idea. Recycled some little used registers to free SP. Perf should be roughly the same.
2021-04-26Fix RTC support for MIPSDavid Guillen Fandos
2021-04-04Fix palette writes in MIPSDavid Guillen Fandos
Was not writing to the right address (but decoded memory was working). Most game worked well except those that depend on modifying the existing palette bits (instead of copying from ROM/RAM). Fixes several games.
2021-04-03Do not use stack in mips stubsDavid Guillen Fandos
No need for it (faster) and avoid mis-aligning it across calls

Handle already translated blocks in the ARM asm to speed up indirect branches (affect some games more than others)

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.

Make ewram memory linear
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.

Adding Normmatt's BIOS as a built-in BIOS
2021-03-22Adding Normmatt's BIOS as a built-in BIOSDavid Guillen Fandos
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).

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.

Remove BIOS reserved translation area
2021-03-17Remove BIOS reserved translation areaDavid Guillen Fandos
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.

Rewrite the MIPS stub backend to add OpenDingux
2021-03-16Simplify open load handling for MIPS and fix other archesDavid Guillen Fandos
Also rewrite a bit memory handlers for smaller functions.
2021-03-16Add Dingux supportDavid Guillen Fandos
Uses a different cache primitive and a differend madd(u) encoding. Also added a flag for BGR vs RGB color output (since PSP is assuming to be BGR for speed). Aside from that the ABI required some special function calls for PIC.
