padmgr and related (#71)
* In process of moving changes over from old repo
* Merged in changes
* Finished import of padmgr changes from old repo
* Adjusted some volatile
* Improving padmgr volatile situation
* Almost matched osReadMempak
* Working on osMempakDataCRC
* Explanations and equivalents but no matches for osMempakAddrCRC and osMempakDataCRC
* OK after merge
* Matched osMempakAddrCRC and osMempakDataCRC
* Matched osReadMempak
* Updated PadMgr function names to be less like original code
* Changed variable names to make them further from original code
* Changed names and it stopped matching
* Undid clang-format steamrollering whitespace memes
* Cleaned up Input names
* More formatting changes
* Moved padmgr to z64.h, deleted padmgr.h

It might also copy padding data (?), and if the size is 3 (mod 4) it may also generate `lwr`/`swr` instructions (like array initialization). +Sometimes, copying small structs with members that fit nicely into primitive types will use normal `lw`, `lh`, etc. instructions. But, usually copying larger structs will use `lwl`/`lwr` instructions, regardless of the internal data. Also, regalloc for struct copying is different between IDO V5.3 and V7.1. If this is the only non-matching in your function, try the other compiler. + ### Register allocation TODO: we really need to figure this out. |
