This new version is much more aggressive about doing "full" reduction in

reduces register pressure.

opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.

Now that we have everything nicely factored (e.g. asmprinter is not
...
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.
Some notes:
1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives. I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global. If .globl is
actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
before. If this is undesirable, it should explicitly opt out of these
things by clearing the relevant fields of MCAsmInfo.
This leads to a nice diffstat:

The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in

the various MOV (register) instructions (16-bit Thumb), including tBRIND (the

only specifies the register class, which includes both hi-and-lo registers.

An unaligned ldr causes a trap, and is then emulated by the kernel with

Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg.
...
For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

Teach dag combine to fold the following transformation more aggressively:

Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness.

Fixes to the X86 disassembler:
...
Made LEA memory operands emit only 4 MCInst operands.
Made the scale operand equal 1 for instructions that have no
SIB byte.

While converting one of the operands to a memory operand, we need to check if it is Legal and does not result into a cyclic dep.

Add more plumbing. This time in the LowerArguments and "get" functions which
...
return partial registers. This affected the back-end lowering code some.
Also patch up some places I missed before in the "get" functions.

Fix setting and default setting of code model for jit. Do this
