2009-08-30util: Auto generate pixel format accessor functions fromJosé Fonseca
This has several advantages over the u_ - not hand written - no intermediate memcpy of raw pixels - supports 4 ubytes in addition to floats - no need to pass a pipe_transfer It also has (hopefully temporary) limitations: - no support for YUV - no support for SRGB

2009-08-29util: Make pixel format layout more meaningful.José Fonseca
Namelly, explicitly distinguish formats coded by arithmetic manipulation, from formats layed out in array.
2009-08-29util: Don't commit u_format_table.cJosé Fonseca
At least not until stabilizes, to reduce noise.
2009-08-29util: Fix r5g6b5 description.José Fonseca
2009-08-29util: Pixel format database.José Fonseca
There are some inconsistencies in pipe_format, but above all, there simply aren't enough bits in an enum to conveniently store all information about a pixel format we need to be able to dynamically generate pixel packing/unpacking code.

2009-08-24tgsi: Pass pipe_context as a parameter to ureg_create_shader.José Fonseca
Simplifies migration to tgsi_ureg. (cherry picked from commit f574398c07c41cb8d31249a7186fc178ef7d552a)
2009-08-24tgsi: add generic instruction builderKeith Whitwell
When translating an incoming shader (rather than building one from scratch) it's preferable to be able to call a single, generic instruction emitter rather than figuring out which of the opcode-specific functions to call.
2009-08-20tgsi: check for SOA dependencies in SSE and PPC code generatorsBrian Paul
Fall back to interpreter for now. This doesn't happen very often.
2009-08-20tgsi: handle SOA dependencies for MOV/SWZBrian Paul
SOA dependencies can happen when a register is used both as a source and destination and the source is swizzled. For example: MOV T, T.yxwz; would expand into: MOV t0, t1; MOV t1, t0; MOV t2, t3; MOV t3, t2; The second instruction will produce the wrong result since we wrote to t0 in the first instruction. We need to use an intermediate temporary to fix this. This will take more work to fix for all TGSI instructions. This seems to happen with MOV instructions more than anything else so fix that case now and warn on others. Fixes piglit glsl-vs-loop test (when not using SSE). See bug 23317.
2009-08-20tgsi: added tgsi_full_instruction::Flags fieldBrian Paul
Users of the parser can make use of this.

2009-08-19tgsi: add missing functionality to support instructions with labelsKeith Whitwell
Could previously emit opcodes with label arguments, but was no way to patch them with the actual destinations of those labels. Adds two functions: ureg_get_instruction_number - to get the id of the next instruction to be emitted ureg_fixup_label - to patch an emitted label to point to a given instruction number. Need some more complex examples than u_simple_shader, so far this has only been compile-tested.

2009-08-13draw: cope with more primitives in draw_pipeline_runKeith Whitwell
This previously was used only for decomposed (POINT/LINE/TRI) primitives, but for some time a full range of primitives could end up in here. Fixes trivial/lineloop-clip on softpipe, among others. (cherry picked from commit 87cd8a3b8a2407b30916be418ff2f95dfea5d2ad)

2009-08-13tgsi: use REALLOC for growing token poolKeith Whitwell
2009-08-13util: silence warnings for third REALLOC argumentKeith Whitwell
Our fallback realloc path requires an old_size argument, but the posix varient doesn't need this. Add some code to avoid gcc unused variable warnings for this extra argument.

2009-08-13util: convert u_simple_shaders to use tgsi_uregKeith Whitwell
Much nicer now.
2009-08-13tgsi: add tgsi_ureg, a simplified tgsi shader builderKeith Whitwell
This is modelled on the nice & easy-to-use facilities we had for building shaders in mesa, eg. in texenvprogram.c and friends. Key points include pass-by-value register structs that can be manipulated in a functional style, eg: negate(swizzle(reg, X,X,X,X)) and per-opcode instruction functions, eg: emit_MOV( p, writemask(dst, 0x1), negate(src)); and similar. Additionally, the interface allows mixed emit of instructions and decls, which are sorted out internally to obey TGSI ordering. Immediates may be emitted at any time and are scanned against existing immediates to try and reduce redundancy. Not all TGSI functionality is accessible through this interface, but most or all of what mesa uses should be.
2009-08-12Merge branch 'new-frag-attribs'Brian Paul
This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these attributes were packed with the FOG attribute. That made things complicated elsewhere.
2009-08-11gallium: Add texture usage information to surface_buffer_createJakob Bornecrantz
We need aditional meta data about the usage of the surface in softpipe because we need to be able tell the diffrence between PRIMARY and DISPLAY_TARGET surfaces.
