What is the function of the ARM register in the picture, and how can I get all the register functions of 8Gen3?

Don't use decompiler if you realy want to understand.
This looks like pseudo functions.
Check asm code, than check ref manual.

Don't the git.codelinaro.org repos sometimes contain partial register definitions for certain crap?
