Dan Gohman c76909abfe Improve MachineMemOperand handling. ... - Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions. This eliminates MachineInstr's std::list member and allows the data to be created by isel and live for the remainder of codegen, avoiding a lot of copying and unnecessary translation. This also shrinks MemSDNode. - Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated fields for MachineMemOperands. - Change MemSDNode to have a MachineMemOperand member instead of its own fields with the same information. This introduces some redundancy, but it's more consistent with what MachineInstr will eventually want. - Ignore alignment when searching for redundant loads for CSE, but remember the greatest alignment. Target-specific code which previously used MemOperandSDNodes with generic SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range so that the SelectionDAG framework knows that MachineMemOperand information is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82794 91177308-0d34-0410-b5e6-96231b3b80d8		2009-09-25 20:36:54 +00:00
