* rename MachineInstr::setInstrDescriptor -> setDescChris Lattner2008-01-111-3/+3

* rename TargetInstrDescriptor -> TargetInstrDesc.Chris Lattner2008-01-071-1/+1
| | | | | | | | 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
* Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflectsChris Lattner2008-01-071-1/+1
| | | | | | | | | | | | | | | | | | 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

* Fix a problem where lib/Target/TargetInstrInfo.h would include and useChris Lattner2008-01-012-2/+2
| | | | | | | | | | | a header file from libcodegen. This violates a layering order: codegen depends on target, not the other way around. The fix to this is to split TII into two classes, TII and TargetInstrInfoImpl, which defines stuff that depends on libcodegen. It is defined in libcodegen, where the base is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45475 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename SSARegMap -> MachineRegisterInfo in keeping with the idea Chris Lattner2007-12-311-17/+17
| | | | | | | | | | | | | | | | that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45467 91177308-0d34-0410-b5e6-96231b3b80d8
* Add new shorter predicates for testing machine operands for various types: Chris Lattner2007-12-303-11/+15
| | | | | | | | | | | | | | e.g. MO.isMBB() instead of MO.isMachineBasicBlock(). I don't plan on switching everything over, so new clients should just start using the shorter names. Remove old long accessors, switching everything over to use the short accessor: getMachineBasicBlock() -> getMBB(), getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45464 91177308-0d34-0410-b5e6-96231b3b80d8

If not, then there is the potential for the stack to be changed while the stack's being used by another instruction (like a call).

This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43688 91177308-0d34-0410-b5e6-96231b3b80d8

* Long live the exception handling!Anton Korobeynikov2007-07-142-4/+6
| | | | | | | | | | | | | | | | This patch fills the last necessary bits to enable exceptions handling in LLVM. Currently only on x86-32/linux. In fact, this patch adds necessary intrinsics (and their lowering) which represent really weird target-specific gcc builtins used inside unwinder. After corresponding llvm-gcc patch will land (easy) exceptions should be more or less workable. However, exceptions handling support should not be thought as 'finished': I expect many small and not so small glitches everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39855 91177308-0d34-0410-b5e6-96231b3b80d8
