Duncan Sands aaffa05d0a There are no longer any places that require a
MERGE_VALUES node with only one operand, so get
rid of special code that only existed to handle
that possibility.

//===- README.txt - Notes for improving CellSPU-specific code gen ---------===//

This code was contributed by a team from the Computer Systems Research
Department in The Aerospace Corporation:

- Scott Michel (head bottle washer and much of the non-floating point
  instructions)
- Mark Thomas (floating point instructions)
- Michael AuYeung (intrinsics)
- Chandler Carruth (LLVM expertise)
- Nehal Desai (debugging, RoadRunner SPU expertise)

--WARNING--:
--WARNING--: The CellSPU work is work-in-progress and "alpha" quality code.
--WARNING--:

If you are brave enough to try this code or help to hack on it, be sure
to add 'spu' to configure's --enable-targets option, e.g.:

        ./configure <your_configure_flags_here> \
           --enable-targets=x86,x86_64,powerpc,spu

TODO:
* Finish branch instructions, branch prediction

  These instructions were started, but only insofar as to get llvm-gcc-4.2's
  crtbegin.ll working (which doesn't.)

* Double floating point support

  This was started. "What's missing?" to be filled in.

* Intrinsics

  Lots of progress. "What's missing/incomplete?" to be filled in.
