Dan Gohman 3311a1f8f0 Fix a post-RA scheduling dependency bug. ... If a MachineInstr doesn't have a memoperand but has an opcode that is known to load or store, assume its memory reference may alias *anything*, including stack slots which the compiler completely controls. To partially compensate for this, teach the ScheduleDAG building code to do basic getUnderlyingValue analysis. This greatly reduces the number of instructions that require restrictive dependencies. This code will need to be revisited when we start doing real alias analysis, but it should suffice for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63370 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-30 02:49:14 +00:00
