- Author: zero_gravity
- Log message:
- - new instruction added: NEG Rd, Rx (Rd <- 0 - Ra)
- instruction is built from redundant SUB with identical operands (SUB Rd, Ra, Ra; will always result in 0)
- since there are other instructions to clear a register, the redundant SUB has been recoded to perform the NEG operation
- NEG operation added to documentary and assembler
