- Fix bug 3185, with misc other cleanups. - Needed to implement SPUInstrInfo::InsertBranch(). CAUTION: Not sure what gets or needs to get passed to InsertBranch() to insert a conditional branch. This will abort for now until a good test case shows up. llvm-svn: 60811 |

//===- 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.
