Evan Cheng 46668e09be Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When ... set, these flags indicate the instructions source / def operands have special register allocation requirement that are not captured in their register classes. Post-allocation passes (e.g. post-alloc scheduler) should not change their allocations. e.g. ARM::LDRD require the two definitions to be allocated even / odd register pair. llvm-svn: 83196		2009-10-01 08:21:18 +00:00
