Evan Cheng fd33cb316f Clean up sub-register implementation by moving subReg information back to ... MachineOperand auxInfo. Previous clunky implementation uses an external map to track sub-register uses. That works because register allocator uses a new virtual register for each spilled use. With interval splitting (coming soon), we may have multiple uses of the same register some of which are of using different sub-registers from others. It's too fragile to constantly update the information. llvm-svn: 44104		2007-11-14 07:59:08 +00:00
