It looks like the committed version removed the space after "insn".
Was that intentional?  It now triggers on MIPS because of the frame-related
(insn/f) prologue instruction that stores the link register.  The posted
version works for me FWIW.

And I guess this shows that it'd be worth having a comment saying _why_
the space is needed. :-)
