Just a few missing AltiVec instructions

[icantplayy]

While working on mcla ive come across some missing instruction errors, from reading on here ive been able to implement some that I need from the BBB_MoreInstructions branch and using the Xenia docs ive found pdfs containing the rest of the instructions I need to implement, ive been able to implement most of the rest of them but since this is my first dive into instruction sets and stuff like that im having trouble implementing these instructions:

vpkuwus
vpkuwum
vpkuhum

I see that vpkuhus was implemented in the BBB_MoreInstructions branch and vpkshus is in the main branch but their implementations differ quite a bit, can anyone help me implement these missing instructions or give me insight on how I can implement them myself?

Thank you!

Also do the same for this, because this my repository not only for my project, but universaly and I try to collect instructions regularly:
