Implement all Instructions from Xenia CPU Tests

[tomcl7]

All of the instructions have been tested against Xenia's CPU tests and are passing.

The only remaining unimplemented instructions from the CPU tests are vslo and vrlo.

[testdriveupgrade]

Your instructions are very useful. Shall you implement these functions: (fsqrte, lq) - they are used in a lot of projects(but I don't understand how to use xenia/test-bin for debug). I'm working on some recomp project.

Hello there, I just wanted to say you've done a great job in terms of translating all the oppcodes in the reccompiler.

I'm trying to translate a different game (SM Edge of Time), but I am running into an issue where I don't have all the oppcodes recognized.

bdnzt
bdzf
lbzux
ldux
lfdu
lfsu
lfsux
lhau
lhzu
lhzux
lwzux
stbux
stdux
stfdu
stfsu
stfsux
sthu
sthux

Any chance you could help guide me in the right direction?

You can try this: https://github.com/testdriveupgrade/XenonRecompUnlim (works without simd_wrapper, but less commands)
or this (but there is simde_wrapper which works bad on windows, only in linux: https://github.com/Fable2Recomp/XenonRecomp And also my other fork of it with biggest count of commands(at this moment): https://github.com/testdriveupgrade/XenonRecompUnlimited/ (There some new and some from fable2recomp changed to implemented in this merge. (they works better)

@testdriveupgrade The one that you made https://github.com/testdriveupgrade/XenonRecompUnlimited/ mostly works!
Here's my console log. It seems I am only missing one instruction: vrlimi128. Any chance you know how to place it in your code?

maybe I've forgotten to add it, just borrow from this:
case PPC_INST_VRLIMI128: { constexpr size_t shuffles[] = { _MM_SHUFFLE(3, 2, 1, 0), _MM_SHUFFLE(2, 1, 0, 3), _MM_SHUFFLE(1, 0, 3, 2), _MM_SHUFFLE(0, 3, 2, 1) }; println("\t_mm_store_ps({}.f32, _mm_blend_ps(_mm_load_ps({}.f32), _mm_permute_ps(_mm_load_ps({}.f32), {}), {}));", v(insn.operands[0]), v(insn.operands[0]), v(insn.operands[1]), shuffles[insn.operands[3]], insn.operands[2]); break; }

I actually managed to fork the repository that you made and edited the code myself with the proper translation. I have already updated my repository and it works!

My next issue that I have is that I cannot find the sizes of the addresses/functions for the jump tables. Do you happen to have a tutorial on how to do that?

1)try to find setjmp and longjmp, game can use them(by finding RtlUnwind , or if not, it means game not use them):
https://github.com/hedge-dev/XenonRecomp?tab=readme-ov-file#longjmp--setjmp
My projects aren't use it, then I'm not sure in this stage
2)Use this script to collect the boundaries: (there are some instruction): #98

Why did you close it?

[tomcl7]

It seemed there was no interest from the maintainers of this repository. I will reopen a PR if there is interest.

[testdriveupgrade]

Why did you close it?

This is the reason, why a lot of developers create their own forks(like Xenia Canary for example). Also what are you think about my guide (it's a first part: https://www.youtube.com/watch?v=w-1Pgn5V3wY). Later I'll make it better and we can add on the main page in readme.md for helping to begginers

It's not that there's no interest, we're just taking a break from recompilation projects. The PRs will take a while to get reviewed.
