discussion of this change. Boy are my fingers tired. ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45411 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-14Clean up sub-register implementation by moving subReg information back toEvan Cheng
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
2007-10-13Optionally create a MachineInstr without default implicit operands.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42945 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-12EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG likeEvan Cheng
(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
