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.

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.

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.

- eliminate the auxInfo union, merging it into the contents union. This shaves
4 bytes off MachineOperand on a 32-bit machine.
- Use accessors in ctor methods.
- Add comments.
llvm-svn: 45462
- Eliminate the static "print" method for operands, moving it
into MachineOperand::print.
- Change various set* methods for register flags to take a bool
for the value to set it to. Remove unset* methods.
- Group methods more logically by operand flavor in MachineOperand.h
llvm-svn: 45461
- Add getParent() accessors.
- Move SubReg out of the AuxInfo union, to make way for future changes.
- Remove the getImmedValue/setImmedValue methods.
- in some MachineOperand::Create* methods, stop initializing fields that are dead.
MachineInstr:
- Delete one copy of the MachineInstr printing code, now there is only one dump
format and one copy of the code.
- Make MachineOperand use the parent field to get info about preg register names if
no target info is otherwise available.
- Move def/use/kill/dead flag printing to the machineoperand printer, so they are
always printed for an operand.

return attributes on the floor. In the case of a call
to a varargs function where the varargs arguments are
being removed, any call attributes on those arguments
need to be dropped. I didn't do this because I plan to
make it illegal to have such attributes (see next patch).
With this change, compiling the gcc filter2 eh test at -O0
and then running opt -std-compile-opts on it results in
a correctly working program (compiling at -O1 or higher
results in the test failing due to a problem with how we
output eh info into the IR).

calls 'nounwind'. It is important for correct C++
exception handling that nounwind markings do not get
lost, so this transformation is actually needed for
correctness.
