Found strange Davik opcode

Question

Who can help me what command meaning:

rsub-int/lit8 v9, v0, 0x8. 

I tried to search, but I got nothing about it. Thank you.

Answer 1

Perform twos-complement reverse subtraction op on the indicated register (first argument) and literal value (second argument), storing the result in the destination register.
