Dan Gohman cd25487258 Pool-allocation for MachineInstrs, MachineBasicBlocks, and ... MachineMemOperands. The pools are owned by MachineFunctions. This drastically reduces the number of calls to malloc/free made during the "Emit" phase of scheduling, as well as later phases in CodeGen. Combined with other changes, this speeds up the "instruction selection" phase of CodeGen by 10% in some cases. llvm-svn: 53212		2008-07-07 23:14:23 +00:00
