if the following are true:- instruction #1 is
addi dst=8 src=4 imm=0
- the PC at time 1 = 1
- value of cell 7 at time 1 = 13
addi dst=8 src=4 imm=0
then value of cell 7 at time 2 = 13
Start from the conclusion and work back up the proof. Click the arrow to show the parents.
- value of cell 7 at time 2 = 13,
if the following are true:
- a = b
- b = c
then a = c
- value of cell 7 at time 2 = value of cell 7 at time 1,
if the following are true:
- a = b
- a = c
then b = c
- value of cell 7 at time (1 + 1) = value of cell 7 at time 2,
if 1 + 1 = 2, then value of cell 7 at time (1 + 1) = value of cell 7 at time 2
- 1 + 1 = 2, 1 + 1 = 2
- value of cell 7 at time (1 + 1) = value of cell 7 at time 1,
if the following are true:
- instruction #i is
addi dst=dst src=src imm=imm
- the PC at time t = i
- not (other = dst)
then value of cell other at time (t + 1) = value of cell other at time t
- instruction #1 is
addi dst=8 src=4 imm=0
- the PC at time 1 = 1
- not (7 = 8), not (7 = 8)
- instruction #i is
- value of cell 7 at time 1 = 13
