* mesa, st/mesa: fix gl_FragCoord with FBOs in GalliumMarek Olšák2010-12-032-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | gl_FragCoord.y needs to be flipped upside down if a FBO is bound. This fixes: - piglit/fbo-fragcoord - https://bugs.freedesktop.org/show_bug.cgi?id=29420 Here I add a new program state STATE_FB_WPOS_Y_TRANSFORM, which is set based on whether a FBO is bound. The state contains a pair of transformations. It can be either (XY=identity, ZW=transformY) if a FBO is bound, or (XY=transformY, ZW=identity) otherwise, where identity = (1, 0), transformY = (-1, height-1). A classic driver (or st/mesa) may, based on some other state, choose whether to use XY or ZW, thus negate the conditional "if (is a FBO bound) ...". The reason for this is that a Gallium driver is allowed to only support WPOS relative to either the lower left or the upper left corner, so we must flip the Y axis accordingly again. (the "invert" parameter in emit_wpos_inversion) NOTE: This is a candidate for the 7.9 branch. Signed-off-by: Marek Olšák <[email protected]> Signed-off-by: Brian Paul <[email protected]>

* ir_to_mesa: Detect and emit MOV_SATs for saturate constructs.Eric Anholt2010-11-191-0/+32
| | | | | The goal here is to avoid regressing performance on ir_to_mesa drivers for fixed function fragment shaders requiring saturates.
* glsl: Combine many instruction lowering passes into one.Kenneth Graunke2010-11-191-3/+2
| | | | | | | This should save on the overhead of tree-walking and provide a convenient place to add more instruction lowering in the future. Signed-off-by: Ian Romanick <[email protected]>
* glsl: Add ir_quadop_vector expressionIan Romanick2010-11-191-0/+132
| | | | | | | | | | The vector operator collects 2, 3, or 4 scalar components into a vector. Doing this has several advantages. First, it will make ud-chain tracking for components of vectors much easier. Second, a later optimization pass could collect scalars into vectors to allow generation of SWZ instructions (or similar as operands to other instructions on R200 and i915). It also enables an easy way to generate IR for SWZ instructions in the ARB_vertex_program assembler.
* glsl: Eliminate assumptions about size of ir_expression::operandsIan Romanick2010-11-191-1/+1
| | | | This may grow in the near future.
* glsl: Add ir_unop_sin_reduced and ir_unop_cos_reducedIan Romanick2010-11-191-0/+110
| | | | | | | | | | | | The operate just like ir_unop_sin and ir_unop_cos except that they expect their inputs to be limited to the range [-pi, pi]. Several GPUs require this limited range for their sine and cosine instructions, so having these as operations (along with a to-be-written lowering pass) helps this architectures. These new operations also matche the semantics of the GL_ARB_fragment_program SCS instruction. Having these as operations helps in generating GLSL IR directly from assembly fragment programs.
* ir_to_mesa: Generate smarter code for some conditional movesIan Romanick2010-11-181-12/+99
| | | | | | | Condiation moves with a condition of (a < 0), (a > 0), (a <= 0), or (a >= 0) can be generated with "a" directly as an operand of the CMP instruction. This doesn't help much now, but it will help with assembly shaders that use the CMP instruction.

* i965: Add support for register spilling.Eric Anholt2010-10-212-0/+65
| | | | | It can be tested with if (0) replaced with if (1) to force spilling for all virtual GRFs. Some simple tests work, but large texturing tests fail.
* glsl: Slightly change the semantic of _LinkedShadersIan Romanick2010-10-141-3/+13
| | | | | | | | | | | | | | | Previously _LinkedShaders was a compact array of the linked shaders for each shader stage. Now it is arranged such that each slot, indexed by the MESA_SHADER_* defines, refers to a specific shader stage. As a result, some slots will be NULL. This makes things a little more complex in the linker, but it simplifies things in other places. As a side effect _NumLinkedShaders is removed. NOTE: This may be a candidate for the 7.9 branch. If there are other patches that get backported to 7.9 that use _LinkedShader, this patch should be cherry picked also.
* glsl: Add a new ir_unop_round_even opcode for GLSL 1.30's roundEven.Kenneth Graunke2010-10-141-0/+1
| | | | Also, update ir_to_mesa's "1.30 is unsupported" case to "handle" it.

* glsl: Fix incorrect assertionIan Romanick2010-10-121-1/+1
| | | | | | | This assertion was added in commit f1c1ee11, but it did not notice that the array is accessed with 'size-1' instead of 'size'. As a result, the assertion was off by one. This caused failures in at least glsl-orangebook-ch06-bump.

* glsl: Rework assignments with write_masks to have LHS chan count match RHS.Eric Anholt2010-09-221-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that most people new to this IR are surprised when an assignment to (say) 3 components on the LHS takes 4 components on the RHS. It also makes for quite strange IR output: (assign (constant bool (1)) (x) (var_ref color) (swiz x (var_ref v) )) (assign (constant bool (1)) (y) (var_ref color) (swiz yy (var_ref v) )) (assign (constant bool (1)) (z) (var_ref color) (swiz zzz (var_ref v) )) But even worse, even we get it wrong, as shown by this line of our current step(float, vec4): (assign (constant bool (1)) (w) (var_ref t) (expression float b2f (expression bool >= (swiz w (var_ref x))(var_ref edge)))) where we try to assign a float to the writemasked-out x channel and don't supply anything for the actual w channel we're writing. Drivers right now just get lucky since ir_to_mesa spams the float value across all the source channels of a vec4. Instead, the RHS will now have a number of components equal to the number of components actually being written. Hopefully this confuses everyone less, and it also makes codegen for a scalar target simpler. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* glsl: introduce ir_binop_all_equal and ir_binop_any_equal, allow vector cmpsLuca Barbieri2010-09-131-1/+7
| | | | | | | | | | | | | | | | | Currently GLSL IR forbids any vector comparisons, and defines "ir_binop_equal" and "ir_binop_nequal" to compare all elements and give a single bool. This is highly unintuitive and prevents generation of optimal Mesa IR. Hence, first rename "ir_binop_equal" to "ir_binop_all_equal" and "ir_binop_nequal" to "ir_binop_any_nequal". Second, readd "ir_binop_equal" and "ir_binop_nequal" with the same semantics as less, lequal, etc. Third, allow all comparisons to acts on vectors. Signed-off-by: Ian Romanick <[email protected]>
