-;; On the mips16, reload will sometimes decide that a pseudo register
-;; should go into $24, and then later on have to reload that register.
-;; When that happens, we get a load of a general register followed by
-;; a move from the general register to $24 followed by a branch.
-;; These peepholes catch the common case, and fix it to just use the
-;; general register for the branch.
