I am REing some iPhone code, and want to know what the following OR instruction does:
The logical OR instruction above does not have operand2.
0001d772 2000 movs r0, #0
0001d774 4300 orrs r0, r0
0001d776 0611 lsls r1, r2, #24
Does this mean?:
R0 |= R0 (which I guess only have the effect of possibly setting the Z-flag?)
Feedback is greatly appreciated
[edit: my guess was correct, R0 |= R0]
