The br statement branches to a loop, block, or if.

Other variants of br are br_if for branching on condition, and br_table for branching to different blocks based on an argument.

Try it


;; 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
