| //===- 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) |

| --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. |
