* MachineOperand:Chris Lattner2007-12-301-57/+38
| | | | | | | | | | | | | | | | | | | - Add getParent() accessors. - Move SubReg out of the AuxInfo union, to make way for future changes. - Remove the getImmedValue/setImmedValue methods. - in some MachineOperand::Create* methods, stop initializing fields that are dead. MachineInstr: - Delete one copy of the MachineInstr printing code, now there is only one dump format and one copy of the code. - Make MachineOperand use the parent field to get info about preg register names if no target info is otherwise available. - Move def/use/kill/dead flag printing to the machineoperand printer, so they are always printed for an operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45460 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up sub-register implementation by moving subReg information back toEvan Cheng2007-11-141-0/+2
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44104 91177308-0d34-0410-b5e6-96231b3b80d8
* Optionally create a MachineInstr without default implicit operands.Evan Cheng2007-10-131-4/+5

* EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG likeEvan Cheng2007-10-121-0/+18
| | | | | | | | | | (almost) a register copy. However, it always coalesced to the register of the RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub- register uses which adds subtle complications to load folding, spiller rewrite, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42899 91177308-0d34-0410-b5e6-96231b3b80d8
