* llvmpipe: native line rasterization with correct pixel rasterizationHui Qi Tay2010-08-271-29/+213
| | | | | Line rasterization that follows diamond exit rule. Can still optimize logic for start/endpoints.
* llvmpipe: native rasterization for linesHui Qi Tay2010-08-2711-22/+685
| | | | | Rasterize lines directly by treating them as 4-sided polygons. Still need to check the exact pixel rasteration.

* llvmpipe: intrinsics version of triangle coeficient calculationKeith Whitwell2010-08-275-300/+577
| | | | | | Looks nice, but makes almost no impact on performance - maybe a percent or so in isosurf, nothing elsewhere. May be of use later on.

* Revert "r600g: simplify states"Dave Airlie2010-08-2715-8277/+1720
| | | | | | | | | This reverts commit bd25e23bf3740f59ce8859848c715daeb9e9821f. Apart from introducing a lot of hex magic numbers and being highly impenetable code, it causes lots of lockups on an average piglit run that always runs without lockups. Always run piglit before/after doing big things like this.
* r600g: add initial if/else/endif supportDave Airlie2010-08-274-12/+170
| | | | | | | | | this adds handling for some more CF instructions and conditions also adds parameter for stack size emission These seem to pass on VS with the stack size hack but not on FS, TODO: fix FS + stack size calcs
* r600g: optimise op2 and swapped op2 emission.Dave Airlie2010-08-271-48/+37
| | | | | | this makes op2 emission smaller, since it skips instructions that don't write to the dst. not sure if this could have unwanted side effects but try it and see.
* r600g: add exp support in theory.Dave Airlie2010-08-271-1/+105
| | | | though it isn't passing the test, and this instruction is pure bonghits.
* r600g: add DPH support.Dave Airlie2010-08-271-1/+8

* i965: Add preliminary support for uniforms to the new FS backend.Eric Anholt2010-08-261-8/+55
| | | | +269 piglits
* i965: Abort on gl_FragDepth in the new FS backend for now.Eric Anholt2010-08-261-0/+1
| | | | | It hangs the GPU due to FB_WRITE handling being incomplete. There are bigger issues to handle first.
* i965: Fix up and actually enable the NewShader and NewShaderProgram hooks.Eric Anholt2010-08-262-3/+8
|
* i965: Hack in avoidance of c++ reserved keyword in libdrm.Eric Anholt2010-08-261-0/+8
| | | | | I'm also fixing this upstream in libdrm, but this avoids new libdrm dependency for the moment.
* i965: Add GLSL IR-level source annotation and comments to new FS debug.Eric Anholt2010-08-261-5/+83
| | | | | This should make debugging way easier, as now we have context for reading large programs.
* i965: Use the implied move in brw_math() in the new FS.Eric Anholt2010-08-261-2/+1
|
* i965: Add support for in varyings to the new FS codegen.Eric Anholt2010-08-261-55/+390
| | | | At least some tests, like glsl-vs-sign, now work.
* i965: Start building the codegen visitor.Eric Anholt2010-08-261-10/+659
| | | | This can successfully emit a real program that generates magenta now.
* i965: Start building direct GLSL2 IR to 965 assembly codegen.Eric Anholt2010-08-264-17/+381
| | | | | | | | | | | Our channel-expressions and vector-splitting changes now happen into a private copy of the IR that we maintain for ourselves. Uniform assignment still happens by the core, so we continue using Mesa IR generation not just for swrast fallbacks but also for uniform values (since there's no storage for their contents other than shader_program->FragmentProgram->Parameters->ParameterValues). And most importantly, at the moment no actual codegen is hooked up other than emitting our favorite color to the framebuffer.
* i965: Add new pass to split vectors into scalar variablesEric Anholt2010-08-264-1/+393
| | | | | | | Combined with the previous pass, this lets other optimization passes do their work thanks to ir_tree_grafting. Still have regression in instruction count with INTEL_NEW_FS, but register count is even better.
* i965: Add a pass for the FS to reduce vector expressions down to scalar.Eric Anholt2010-08-264-1/+384
| | | | | | | | | | | | | | | This is a step towards implementing a GLSL IR backend for the 965 fragment shader. Because it has downsides with the current codegen, it is hidden under the environment variable INTEL_NEW_FS. This results in an increase in instruction count at the moment (1444 -> 1752 for glsl-fs-raytrace, 345 -> 359 on my demo), because dot products are turned into a series of multiplies and adds instead of a custom expansion of MULs and MACs, and by not splitting the variable types up we don't get tree grafting and thus there are extra moves of temporary storage. However, register count drops for the non-GLSL path (64 -> 56 on my demo shader) because the register allocator sees all the sub-operations.

| | | | | | Shader inputs appear in source registers, not dst registers. Catches unsupported shaders in glsl-fs-varying-array and Humus RaytracedShadows.
* glsl2: Remove a couple FINISHME comments that have already been resolvedIan Romanick2010-08-261-7/+1

* glsl: Move built-ins to live beyond the global scope.Kenneth Graunke2010-08-261-4/+20
| | | | | | | | | | Per the GLSL 1.20 specification (presumably a clarification of 1.10). Also, when creating user functions, make a new ir_function that shadows the built-in ir_function, rather than adding new signatures. User functions are supposed to hide built-ins, not overload them. Fixes piglit tests redeclaration-{04, 12, 14}.vert.
* glsl: Move is_built_in flag from ir_function_signature to ir_function.Kenneth Graunke2010-08-268-18/+13
| | | | | | Also rename it to "is_builtin" for consistency. Signed-off-by: Ian Romanick <[email protected]>
* glsl: Refactor variable declaration handling.Kenneth Graunke2010-08-261-36/+41
| | | | | | | | | | | | | Moving the check for an earlier variable declaration helps cleanly separate out the re-declaration vs. new declaration code a bit. With that in place, conflicts between variable names and structure types or function names aren't caught by the earlier "redeclaration" error message, so check the return type on glsl_symbol_table::add_variable and issue an error there. If one occurs, don't emit the initializer. Fixes redeclaration-01.vert and redeclaration-09.vert. Signed-off-by: Ian Romanick <[email protected]>
* glsl: Don't add overloads to existing structure constructors.Kenneth Graunke2010-08-263-4/+9
| | | | | | Instead, make a new ir_function and try to add it to the symbol table. Fixes piglit test redeclaration-08.vert.
