Missing xenon cpu instructions

[JayC-03]

All of the games I have tried recompiling seem to fail due to many missing cpu instructions, for example:
'vsubshs': is not a member of 'cpu::op'
'vmrghh': is not a member of 'cpu::op'
'vsr': is not a member of 'cpu::op'
'vctsxs': is not a member of 'cpu::op'

Am I doing something incorrectly?
I thought most cpu instructions were already implemented.

@rexdex I don't see the inline representations of these instructions, but they are clearly emitted in the instruction decoding process. Another merge issue?

Most likely. I'm improving the debugging tools ATM. Soon after this is done I will take a look. Those are quite nice instructions, can be done from memory :)

@rexdex Ah, okay. I checked xenonCPU.h, and I didn't see any of the instructions defined, but they are in xenonInstructionDecoding.cpp for some reason.

@rexdex By the way, this is an amazing project!
I never would have thought anything even close to this would be possible.
I just hope this bug is fixed soon, I have tried decompiling more games and they also fail due to this merge problem.

Thanks! Have faith :) I'm working on the issues. You guys are amazing - it's a lot of powerful motivation for me that you are taking interest in this project.

@JayC-03 : can you provide me with the .xex ? send it to rexdexpl@gmail.com I could take a look to make sure it works properly.

[JayC-03]

@rexdex Check your email :)

@rexdex Can you confirm if this is a merge issue? If not, I can work on implementing these vector functions.

[rexdex]

I've fixed those instructions. I would say 99% are there :)

@sumit0190 Thanks for letting me know to come here, as you can see in xenonCPU.h on my fork I've stubbed a few cpu functions and if search TMP1 you'll find all the ones I did.

Note I did this before the most recent 2 commits.

[sumit0190]

@theTwist84 Nice! Thankfully rex has fixed this issue, because otherwise the vector instructions can be a pain to implement. Let's wait until the next commit to see if these have been put in.

The gist of it is the 2 errors below

error C2039: 'vsubsws': is not a member of 'cpu::op'
error C2039: 'vsububs': is not a member of 'cpu::op'

Useful documentation on PPC assembly

vsubuws also needs to be implemented (working on this).

RPCS3 has quite a lot of PPC opcodes implemented here: https://github.com/RPCS3/rpcs3/blob/master/rpcs3/Emu/Cell/PPUInterpreter.cpp
