2010-07-03mesa: Fix OpenGL ES-only builds.Chia-I Wu
Check FEATURE_GL in _mesa_init_shader_dispatch and _mesa_init_shader_uniform_dispatch. OpenGL ES can not and does not use _mesa_init_<...>_dispatch. This is supposed to be temporary. Ideally, a more flexible way for initializing dispatch tables should be developed.
2010-07-03r300/compiler: Fix loop unrollingTom Stellard
2010-07-03r300/compiler: Use hardware flow control instructions for loops on r500.Tom Stellard
2010-07-03r300/compiler: Don't continue copy propagation inside loops.Tom Stellard
2010-07-03r300/compiler: Print debug info for flow control instructions.Tom Stellard
2010-07-03r300/compiler: Enable hardware IF statements for r500 cards.Tom Stellard
2010-07-03r300/compiler: In the peephole optimizer, ELSE should mark the end of aTom Stellard
block.
2010-07-03r300/compiler: Correctly calculate the max number of iterations for loops.Tom Stellard
2010-07-03r300/compiler: Handle loops in deadcode analysis.Tom Stellard
This also allows us to split the loop emulation into two phases. A tranformation phase which either unrolls loops or prepares them to be emulated, and the emulation phase which unrolls remaining loops until the instruction limit is reached. The second phase is completed after the deadcode analysis in order to get a more accurate count of the number of instructions in the body of loops.
2010-07-02ir_to_mesa: Fix uninitalized value.Kenneth Graunke
2010-07-02osmesa: remove old renderbuffer before adding newBrian Paul
Fixes fd.o bug 10966 when OSMesaMakeCurrent() was called twice. NOTE: This is a candidate for the 7.8 branch.
2010-07-02mesa: updated instruction commentsBrian Paul
2010-07-02ir_to_mesa: Fix up implementation of ir_unop_exp.Eric Anholt
OPCODE_EXP is not to ir_unop_exp what OPCODE_EX2 is to ir_unop_exp2. It's the weird VP approximation helper opcode. Just implement it with OPCODE_POW instead. Fixes glsl-fs-exp.
2010-07-02i965: Add support for the DP2 opcode, which we use for dot(vec2, vec2).Eric Anholt
The original glsl compiler would generate a.x * b.x + a.y * b.y, which we would do mul+mul+add for instead of this mul+mac. Fixes glsl-fs-dot-vec2.
2010-07-02ir_to_mesa: Add support for scalar * mat, vec * mat.Eric Anholt
This is not tested by piglit currently.
2010-07-02ir_to_mesa: Add support for shadow comparison to texture instructions.Eric Anholt
piglit lacks tests for this currently.
2010-07-02ir_to_mesa: Move projection handling out of ir_tex so txb and txl get it.Eric Anholt
Fixes: glsl-fs-texture2dproj-bias glsl-fs-texture2dproj-bias-2
2010-07-02ir_to_mesa: Add support for projected non-shadow/bias/lod texturing.Eric Anholt
Fixes: glsl-fs-texture2dproj glsl-fs-texture2dproj-2
2010-07-02mesa: add geometry shader fields to gl_shader_programBrian Paul
These 3 fields are per shader-program. Copy them into the geometry program at link time for convenient access later. Also, add some missing glGetProgramiv() queries.
2010-07-02ir_to_mesa: Fix sparse swizzling of src regs when a writemask is present.Eric Anholt
Fixes glsl-fs-texture2d-masked.
2010-07-02ir_to_mesa: Don't forget to run the Mesa IR optimization passes.Eric Anholt
With how we generate assignments, the trivial copy propagation in it is really important, and some drivers will really want the register allocation, too.
2010-07-02glsl2: Add a pass to break ir_binop_div to _mul and _rcp.Eric Anholt
This results in constant folding of a constant divisor.
2010-07-02mesa: fix texenv generation when num color bufs == 0Brian Paul
Before, if there were no color buffers enabled (with glDrawBuffers(GL_NONE)) when the texenv program was generated, we'd emit writes to OUTPUT[1] but the OutputsWritten mask was 0. This inconsistency caused an assertion to fail later in the Mesa->TGSI translation. Fixes fd.o bug 28169 NOTE: this is a candidate for the 7.8 branch (and depends on commit b6b9b17d27c570cc99ae339e595cf2f63ca5e8d7).
2010-07-02mesa: add missing error checks in _mesa_program_parameteri()Brian Paul
2010-07-02main: change some GS field types, added commentsBrian Paul
2010-07-02mesa: make the number of draw buffers part of the texenv program key stateBrian Paul
All the state that effects the program should be in the key. This didn't help with bug 28169 but is a good fix anyway. NOTE: this is a low-priority candidate for the 7.8 branch. In practice, this issue might never be hit.
2010-07-02mesa: Silence warning.José Fonseca
2010-07-01glsl2: Conditionally allow optional extensions to be enabledIan Romanick
The only optional extension currently supported by the compiler is GL_EXT_texture_array.
2010-07-01glsl2: Conditionally define preprocessor tokens for optional extensionsIan Romanick
The only optional extension currently supported by the compiler is GL_EXT_texture_array.
2010-07-01mesa: extension flags and version testing for GL 3.x featuresBrian Paul
2010-07-01mesa: entrypoints for GL 3.1 primitive restartBrian Paul
2010-07-01glsl2: Add gl_MaxTextureCoordsIan Romanick
2010-07-01mesa: free xform feedback hash tableBrian Paul
2010-07-01st/mesa: fix commentBrian Paul
2010-07-01ir_to_mesa: Fill in remaining ops, remove default case for expression types.Eric Anholt
We should now have support for all the expression types we need for GLSL 1.20.
2010-07-01ir_to_mesa: Add support for ir_unop_rcp.Eric Anholt
This isn't used at the moment, but will be soon.
2010-07-01glsl2: Add a pass to convert mod(a, b) to b * fract(a/b).Eric Anholt
This is used by the Mesa IR backend to implement mod, fixing glsl-fs-mod.
2010-07-01glsl2: Add ir_unop_fract as an expression type.Eric Anholt
Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
2010-06-30ir_to_mesa: Add support for discard instructions.Eric Anholt
Fixes glsl-fs-discard-01.
2010-06-30ir_to_mesa: Add support for ir_unop_sign.Eric Anholt
Fixes glsl-fs-sign, glsl-vs-sign.
2010-06-30i965: Add support for OPCODE_SSG.Eric Anholt
The old compiler didn't use SSG, and instead emitted SGT/SGT/SUB. We can do a little better for SSG than we do for the SGT series.
2010-06-30ir_to_mesa: Add missing no-op type conversions.Eric Anholt
Fixes glsl-fs-step.
2010-06-30ir_to_mesa: Note which of our expr ops are unsupported 1.30 features.Eric Anholt
2010-06-30ir_to_mesa: Initialize the (we never use it) abs field of Mesa src regs.Eric Anholt
2010-06-30ir_to_mesa: Send the negate field on to Mesa IR.Eric Anholt
Fixes glsl-fs-neg.
2010-06-30ir_to_mesa: When generating a swizzle, respect the reg's current swizzle.Eric Anholt
Fixes depth-tex-modes-glsl.
2010-06-30glsl2: Define new ir_discard instruction.Kenneth Graunke
2010-06-30ir_to_mesa: Support gl_FragDepth.Eric Anholt
Fixes glsl-bug-22603.
2010-06-30mesa: Don't look in unallocatd param slots for parameter values.Eric Anholt
glsl-derivs would add 40.0, 0.0, and 1.0 in order. When we went looking for 0.0, we'd find it in the second slot of the param, and use it, but param->Size would still be 1. When we went to add 1.0 and didn't find it, we'd put allocate it to that second slot and the 0.0 would actualy end up being 1.0. Fixes glsl-derivs, glsl-deriv-varyings.
2010-06-30ir_to_mesa: Fix the indexing of attributes in the program's Attributes.Eric Anholt
This fixes GetAttribLocation returning VERT_ATTRIB_GENERIC1 instead of 1, caught by glsl-dlist-getattriblocation.
