- Incorporate Tilmann Scheller's ISD::TRUNCATE custom lowering patch - Update SPU calling convention info, even if it's not used yet (but can be at some point or another) - Ensure that any-extended f32 loads are custom lowered, especially when they're promoted for use in printf. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60438 91177308-0d34-0410-b5e6-96231b3b80d8 |

//===- 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.
