ARM VFPv2 missing instructions

So, I am decompiling a 3DS game, which uses armv6, as well as the VFP Coprocessor Unit for floating point math instructions. I am... completely missing all of the coprocessor instructions, as well as the 3ds's kernel syscall functions/datatypes. After doing a lot of digging, I still can't... find any plugin or module anything else that I could use to import these instructions into my project?
I would rather not reinvent the wheel here and try to define all these instructions myself, so... where do I even find these?
The VFP floating point math instructions are a much bigger concern to be lacking, and are a much higher priority to have, for me.

It appears that at least vmul and vsqrt instructions are incorrectly wrapped in @if defined(SIMD) as opposed to VFPv2 || VFPv3 || SIMD as they should be. This causes them to disassemble as CDP instructions rather than the appropriate VFP instructions.
