Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it.
...
This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

In some rare cases, the register allocator can spill registers but end up not utilizing registers at all. The fundamental problem is linearscan's backtracking can end up freeing more than one allocated registers. However, reloads and restores might be folded into uses / defs and freed registers might not be used at all.
...
VirtRegMap keeps track of allocations so it knows what's not used. As a horrible hack, the stack coloring can color spill slots with *free* registers. That is, it replace reload and spills with copies from and to the free register. It unfold instructions that load and store the spill slot and replace them with register using variants.
Not yet enabled. This is part 1. More coming.

Enhance ScheduleDAGSDNodesEmit to be more flexible and robust
in the presense of subregister superclasses and subclasses. It
can now cope with the definition of a virtual register being in
a subclass of a use.
Re-introduce the code for recording register superreg classes and
subreg classes. This is needed because when subreg extracts and
inserts get coalesced away, the virtual registers are left in
the correct subclass.

SDIsel processes llvm.dbg.declare by recording the variable debug information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc.
...
Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes.
For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time.

Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects
...
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.

Fix a problem where lib/Target/TargetInstrInfo.h would include and use

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.

Instructions with variable operands (variable_ops) can have a number required

operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
"call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.
Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

Nice tasty llc fixes. These should fix LLC for x86 for everything in
...
SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.

NOP instructions are pseudo-instructions. We should not have them explicitly in
...
our representation, since they are usually special cases of already-existing
instructions.
This abstracts away methods that let a pass create and verify a NOP instruction,
without relying on a `NOP' enum to be in existence in the target's instruction
info descriptor.
