a1719c9130 InstSelectSimple.cpp: Include llvm/iOther.h for ShiftInst.
Add ISel::visitShiftInst() to instruction select shift instructions.
 Add a comment in visitAdd about how to do 64 bit adds.

X86InstrInfo.def: Add register-to-register move opcodes and shift opcodes.

9b87c5c53c * Minor optimization: when merging nodes, merge the smaller one into the
larger one.
     * Handle the case where we are merging two nodes of different size better.

Huge thanks go to Casey Carter for writing this fix, reassociate is now
reoperational!

26fbcec43b Restore support for indirect function calls (which briefly wasn't working
after I removed annotations on MachineInstr for the CallDescriptor).

8f0a16eac6 This fixes all kinds of problems with array handling. There are still bugs to
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

2fdaddf445 Fix two problems:
* Load Implementation can cause unaligned memory accesses, which caused
    problems for sparc.
  * cast from pointer to pointer would zero the upper 32 bits of the pointer
    which obviously causes problems on 64 bit hosts.
