Don't include system headers in the .d files.
Don't use $@ in the makefile rules, as there are two possible targets it could resolve to: use the one that we need explicitly.

values, which means doing extra legalization work.
It would be easier to get this kind of thing right if
there was some documentation...

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.

function, then go ahead and hoist it out of the loop. This is the result:
$ cat a.c
volatile int G;
int A(int N) {
for (; N > 0; --N)
G++;
}
$ llc -o - -relocation-model=pic
_A:
...
LBB1_2: # bb
movl L_G$non_lazy_ptr-"L1$pb"(%eax), %esi
incl (%esi)
incl %edx
cmpl %ecx, %edx
jne LBB1_2 # bb
...
$ llc -o - -relocation-model=pic -machine-licm
_A:
...
movl L_G$non_lazy_ptr-"L1$pb"(%eax), %eax
LBB1_2: # bb
incl (%eax)
incl %edx
cmpl %ecx, %edx
jne LBB1_2 # bb

I'm limiting this to the MOV32rm x86 instruction for now.
