-Subject: [PATCH] arc: Update doloop_end patterns
-
-ARC processor can use LP instruction to implement zero overlay loops.
-The current inplementation doesn't handle the unlikely situation when
-the loop iterator is located in memory.  Refurbish the loop_end insn
-pattern into a define_insn_and_split pattern.
