# This program loops, putting powers of two into $1 at the end of each
# iteration.

addiu $1, $0, 1 # put 1 into register 1

# start of loop
# (copy current PC into register 31 so we can jr $31 later to loop)
addiu $31, $0, PC

addu $2, $1, $0 # copy register 1 into register 2
j skip
# stuff between here and skip should never be executed
or $4, $3, $2

skip:
addu $1, $2, $2 # register 1 gets double the value of register 2
jr $31 # begin next iteration of loop
