Redcode.txt
The Minecraft Redstone-inspired Pseudo-language
Registers and ports
--------------------
R0.. R15 Redstone lines, each a 16 bit SIGNED register, but the value is shifted every instruction
If the top bit is 0, it shifts down,
If thetop bit is 1, it shifts up
C0..15 Cauldrons, respectively pre-filled with "(1<<n)-1"
Instructions
-------------
INV Rd, Rs Negates the bits from source into destination
SUB Rd, Rs Writes the difference between the destination and the source (Rd=Rd-Rs)
REP Rd[, Rs], d Writes the value from source into destination, (1<<d) instructions later (d = 1..4)
CMP Rd, Cs Reads the input from the "cauldron" bus and writes it into the destination
... need something for flow control. "pistons" to change the active instruction? maybe?
