* Remove/modify C backend references from LLVM documentation.David Blaikie2012-06-141-1/+2
| | | | | | Patch by Wei-Ren Chen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158456 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the old register list functions from MCRegisterInfo.Jakob Stoklund Olesen2012-06-011-3/+3
| | | | | | | | | | These functions exposed the layout of the underlying data tables as null-terminated uint16_t arrays. Use the new MCSubRegIterator, MCSuperRegIterator, and MCRegAliasIterator classes instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157855 91177308-0d34-0410-b5e6-96231b3b80d8

* 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
