* CELL: fix colormask code generationRobert Ellison2008-09-231-83/+78
| | | | | | | | | The colormask code generation had assumed that its input packed pixels were in RGBA format. In fact, the format they're in is dependent on the pipe color format. Now the color format is passed in to gen_colormask(), and proper color format-dependent SPU code is generated.
* cell: Fixed bug with absolute, negate, set-negative logic in source fetch ↵Jonathan White2008-09-221-9/+5
| | | | | | for TGSI instructions. The logic should operate on the origin channel not the swizzled channel. Please enter the commit message for your changes.

* cell: flesh out support for other Z/stencil formatBrian Paul2008-09-191-36/+64
| | | | | Also: improve float/int Z conversion. Use clgt instead of cgt in depth test since we're comparing unsigned values.

* CELL: add codegen for logic op, color maskRobert Ellison2008-09-191-6/+137
| | | | | | | | | | | | | | | | - rtasm_ppc_spe.c, rtasm_ppc_spe.h: added a new macro function "spe_load_uint" for loading and splatting unsigned integers in a register; it will use "ila" for values 18 bits or less, "ilh" for word values that are symmetric across halfwords, "ilhu" for values that have zeroes in their bottom halfwords, or "ilhu" followed by "iohl" for general 32-bit values. Of the 15 color masks of interest, 4 are 18 bits or less, 2 are symmetric across halfwords, 3 are zero in the bottom halfword, and 6 require two instructions to load. - cell_gen_fragment.c: added full codegen for logic op and color mask.
* CELL: mark several transient files as .gitignoreRobert Ellison2008-09-181-0/+1
| | | | | | | | | | | | | progs/demos: added new demo "fbo_firecube" progs/glsl: added new demo "pointcoord" src/gallium/drivers/cell/spu: added the g3d_spu executable, a Cell SPU executable file, which seems to be occasionally built as part of the cell driver src/glu/sgi: added "exptmp", a byproduct of the "mklib" process that sometimes gets deleted and sometimes not.

* CELL: finish fragment ops blending (except for unusual D3D modes)Robert Ellison2008-09-181-217/+329
| | | | | | | | | | | | | | | | | | | | - 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.

* CELL: fleshing out the blending fragment opsRobert Ellison2008-09-175-68/+337
| | | | | | | | | | | | | | | | | | | | | - 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...
