* Add a new kind of MachineOperand: MO_RegisterMask.Jakob Stoklund Olesen2012-01-161-0/+15
| | | | | | | | | | | | | | | | | | | | | Register masks will be used as a compact representation of large clobber lists. Currently, an x86 call instruction has some 40 operands representing call-clobbered registers. That's more than 1kB of useless operands per call site. A register mask operand references a bit mask of call-preserved registers, everything else is clobbered. The bit mask will typically come from TargetRegisterInfo::getCallPreservedMask(). By abandoning ImplicitDefs for call-clobbered registers, it also becomes possible to share call instruction descriptions between calling conventions, and we can get rid of the WINCALL* instructions. This patch introduces the new operand kind. Future patches will add RegMask support to target-independent passes before finally the fixed clobber lists can be removed from call instruction descriptions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148250 91177308-0d34-0410-b5e6-96231b3b80d8
