2008-09-18cell: Added SGE and SLE instructions to dispatch functionJonathan White
2008-09-18cell: Added SGE and SLE instructionsJonathan White
2008-09-18CELL: 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.
2008-09-17cell: example of doing fs/fm sequence with fnms in blendingBrian Paul
2008-09-17cell: dump generated code if CELL_DEBUG=asmBrian Paul
2008-09-17CELL: fleshing out the blending fragment opsRobert 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...

2008-09-15i915simple: dri winsys does now compile and worksJakob Bornecrantz
Glxgears hits an assert, but tri works

Fixes glitches seen in morph3d demo.
2008-09-12cell: remove old disassembly/dump code; use dumper code in SPE emitter.Brian Paul

2008-09-12cell: implement colormask on fallback pathBrian Paul
Also, some var renaming and additional comments
2008-09-12gallium: avoid redundant tgsi_exec_machine_bind_shader() calls on draw exec pathBrian Paul
tgsi_exec_machine_bind_shader() isn't cheap so avoiding unecessary calls is a big win. A similar change should be done for softpipe's fragment exec path but extra care needs to be taken with the texture sampler state/params.
2008-09-12gallium: use copy_token() function to avoid type punning/aliasing problemsBrian Paul
This fixes parsing errors seen with optimized builds on PPC (which led to crashes). The memcpy() is heavy-handed, but works. A lighter uint assignment could be used on x86...
2008-09-12cell: fix twiddled tile display for XSHM. Fixed blank window problem.Brian Paul

2008-09-12mesa: get fixed-function program generation working againKeith Whitwell
2008-09-11cell: 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.
