loop statement creates a label that can later be branched to with a
br. The loop instruction doesn't loop by itself; you need to branch to it to actually create a loop.
loop statement is the opposite of the
block statement, in the sense that while branching to a
loop jumps to the beginning of the loop, branching to a
block jumps to the end of the block, that is, out of the block.
;; label the loop so that it can be branched to (loop $my_loop ;; branch to the loop. ;; most of the time you'll want to put this in an if statement and only branch on condition, ;; otherwise you have an infinite loop. br $my_loop )
