Use longer and more explicit names for instance vars (particularly important
...
data structures). Fix the print method to send to the right ostream, not
always cerr. Delete typedefs that are only used once.

Move include/Config and include/Support into include/llvm/Config,

public header files must be under include/llvm/.

Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.

Add a spiller option to llc. A simple spiller will come soon. When we get CFG in the machine code represenation a global spiller will also be possible. Also document the linear scan register allocator but mark it as experimental for now.

Move machine code rewriter and spiller outside the register
...
allocator.
The implementation is completely rewritten and now employs several
optimizations not exercised before. For example for 164.gzip we have
997 loads and 699 stores vs the 1221 loads and 880 stores we have
before.
