Andrew Trick	d24698c8ef	CriticalAntiDepBreaker is no longer needed for armv7 scheduling. ... This is being disabled because it is no longer needed for performance. It is only used by postRAscheduler which is also planned for removal, and it is implemented with an out-dated view of register liveness. It consideres aliases instead of register units, assumes valid kill flags, and assumes implicit uses on partial register defs. Kill flags and implicit operands are error prone and impossible to verify. We should gradually eliminate dependence on them in the postRA phases. Targets that still benefit from this should move to the MI scheduler. If that doesn't solve the problem, then we should add a hook to regalloc to optimize reload placement. llvm-svn: 191348	2013-09-25 00:26:16 +00:00
Lang Hames	b85fcd07df	Lower mem-ops to unaligned i32/i16 load/stores on ARM where supported. ... Add support for trimming constants to GetDemandedBits. This fixes some funky constant generation that occurs when stores are expanded for targets that don't support unaligned stores natively. llvm-svn: 144102	2011-11-08 18:56:23 +00:00
Lang Hames	c47e283430	Make sure short memsets on ARM lower to stores, even when optimizing for size. ... llvm-svn: 143055	2011-10-26 20:56:52 +00:00
