SelectionDAGISel can now natively handle Switch instructions, in the same
...
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary
search tree of basic blocks. The new approach has several advantages:
it is faster, it generates significantly smaller code in many cases, and
it paves the way for implementing dense switch tables as a jump table by
handling switches directly in the instruction selector.
This functionality is currently only enabled on x86, but should be safe for
every target. In anticipation of making it the default, the cfg is now
properly updated in the x86, ppc, and sparc select lowering code.

Add support for TargetConstantPool nodes to the dag isel emitter, and use
...
them in the PPC backend, to simplify some logic out of Select and
SelectAddr.

Use new PPC-specific nodes to represent shifts which require the 6-bit
...
amount handling that PPC provides. These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits. This fixes a miscompilation of crafty with
the new front-end.

add an option to generate completely non-pic code, corresponding to what
...
gcc -static produces on PPC. This is used for building kexts and other things.
With this, materializing the address of a global looks like:
lis r2, ha16(L_H$non_lazy_ptr)
la r3, lo16(L_H$non_lazy_ptr)(r2)
we're still emitting stubs for functions, which is wrong. That is next.

Enable global address legalization, fixing a todo and allowing the removal
...
of some code. This exposes the implicit load from the stubs to the DAG, allowing
them to be optimized by the dag combiner. It also moves darwin specific stuff
out of the isel into the legalizer, and allows more to be moved to the .td file.

Add an initial hack at legalizing GlobalAddress into the appropriate nodes
...
on Darwin to remove smarts from the isel. This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file. However, we can currently emit stuff like
this: :)
li r2, lo16(L_x$non_lazy_ptr)
lis r3, ha16(L_x$non_lazy_ptr)
lwzx r2, r3, r2
The obvious improvements will follow.

When lowering direct calls, lower them to use a targetglobaladress directly
