2008-02-16Fix typos.Bill Wendling

2008-02-10Rename MRegisterInfo to TargetRegisterInfo.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner
Make MachineInstr::getDesc return a reference instead of a pointer, since it can never be null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45695 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner
that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45674 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-14Remove isReg, isImm, and isMBB, and change all their users to use Dan Gohman
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent, and more popular. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41958 91177308-0d34-0410-b5e6-96231b3b80d8
