PRED_NORETURN seems a better match; not that I see anything in
the current source that actually treats them differently other
than generating them, but my grep-fu may be weak and certainly
my crystall-ball-fu is.
After testing (no regressions compared to r204080 before the
breakage), committed.
* config/cris/cris.c (cris_emit_trap_for_misalignment): Replace the
removed PRED_MUDFLAP with PRED_NORETURN. Correct file-path in comment.
