Evan Cheng	d0a66e438f	Add a ARM specific pre-allocation pass that re-schedule loads / stores from ... consecutive addresses togther. This makes it easier for the post-allocation pass to form ldm / stm. This is step 1. We are still missing a lot of ldm / stm opportunities because of register allocation are not done in the desired order. More enhancements coming. llvm-svn: 73291	2009-06-13 09:12:55 +00:00
