2008-09-18 | cell: Added SGE and SLE instructions | Jonathan White | |
2008-09-18 | CELL: finish fragment ops blending (except for unusual D3D modes) | Robert Ellison | |
- Added new "macro" functions spe_float_min() and spe_float_max() to rtasm_ppc_spe.{ch}. These emit instructions that cause the minimum or maximum of each element in a vector of floats to be saved in the destination register. - Major changes to cell_gen_fragment.c to implement all the blending modes (except for the mysterious D3D-based PIPE_BLENDFACTOR_SRC1_COLOR, PIPE_BLENDFACTOR_SRC1_ALPHA, PIPE_BLENDFACTOR_INV_SRC1_COLOR, and PIPE_BLENDFACTOR_INV_SRC1_ALPHA). - Some revamping of code in cell_gen_fragment.c: use the new spe_float_min() and spe_float_max() functions (instead of expanding these calculations inline via macros); create and use an inline utility function for handling "optional" register allocation (for the {1,1,1,1} vector, and the blend color vectors) instead of expanding with macros; use the Float Multiply and Subtract (fnms) instruction to simplify and optimize many blending calculations. | |||

2008-09-17 | cell: dump generated code if CELL_DEBUG=asm | Brian Paul | |
2008-09-17 | CELL: fleshing out the blending fragment ops | Robert Ellison | |
- Added two new debug flags (to be used with the CELL_DEBUG environment variable). The first, "CELL_DEBUG=fragops", activates SPE fragment ops debug messages. The second, "CELL_DEBUG=fragopfallback", will eventually be used to disable the use of generated SPE code for fragment ops in favor of the default fallback reference routine. (During development, though, the parity of this flag is reversed: all users will get the reference code *unless* CELL_DEBUG=fragopfallback is set. This will prevent hiccups in code generation from affecting the other developers.) - Formalized debug message usage and macros in spu/spu_main.c. - Added lots of new code to ppu/cell_gen_fragment.c to extend the number of supported source RGB factors from 4 to 15, and to complete the list of supported blend equations. More coming, to complete the source and destination RGB and alpha factors, and to complete the rest of the fragment operations... | |||

Only one level of if/else/endif nesting is currently working. | |||

2008-09-12 | cell: implement colormask on fallback path | Brian Paul | |
Also, some var renaming and additional comments | |||
2008-09-12 | cell: fix non-debug build error | Brian Paul | |
2008-09-12 | cell: implement swizzling for src regs | Brian Paul | |
2008-09-12 | cell: setup fragment program inputs in SOA format | Brian Paul | |

2008-09-12 | cell: disable calls to old gen code | Brian Paul | |
2008-09-11 | cell: initial support for fragment shader code generation. | Brian Paul | |
TGSI shaders are translated into SPE instructions which are then sent to the SPEs for execution. Only a few opcodes work, no swizzling yet, no support for constants/immediates, etc. | |||
