* mesa: add _NEW_CURRENT_ATTRIB in _mesa_program_state_flags()Brian Paul2011-09-301-2/+5
| | | | | | | | | | | | If color material mode is enabled, constant buffer entries related to the material coefficients will depend on glColor. So add _NEW_CURRENT_ATTRIB to the bitset returned for material-related constants in _mesa_program_state_flags(). This fixes a bug exercised by the new piglit draw-arrays-colormaterial test. Note: This is a candidate for the 7.11 branch.
* ir_to_mesa: Don't assertion fail on remaining GLSL 1.30 ops.Eric Anholt2011-09-281-2/+10
| | | | | | | | | | For hardware drivers, we only have ir_to_mesa called for the purposes of potential swrast fallbacks (basically never on a 1.30 driver), which we don't really care about. This will allow 1.30 to be implemented without rewriting swrast for it. Reviewed-by: Chad Versace <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* mesa: Add a flag to indicate whether a program uses gl_ClipDistance.Paul Berry2011-09-231-0/+2
| | | | | | | | | | | | | | | | | | GLSL 1.30 requires us to use gl_ClipDistance for clipping if the vertex shader contains a static write to it, and otherwise use user-defined clipping planes. Since the driver needs to behave differently in these two cases, we need a flag to record whether the shader has written to gl_ClipDistance. The new flag is called UsesClipDistance. We initially store it in gl_shader_program (since that is the data structure that is available when we check to see whethe gl_ClipDistance was written to), and we later copy it to a flag with the same name in gl_vertex_program, since that is a more convenient place for the driver to access it (in i965, at least).

* glsl: Use a separate div_to_mul_rcp lowering flag for integers.Bryan Cain2011-08-311-1/+1
| | | | | | | | | | | | | | Using multiply and reciprocal for integer division involves potentially lossy floating point conversions. This is okay for older GPUs that represent integers as floating point, but undesirable for GPUs with native integer division instructions. TGSI, for example, has UDIV/IDIV instructions for integer division, so it makes sense to handle this directly. Likewise for i965.

| | | | | | | | | At least for Intel, all our uniform components are of uint32_t size, either float or signed or unsigned int. For uploading uniform data in the driver, it's much easier to upload a full dword per uniform element instead of trying to pick out the bool byte and then fill in the top 3 bytes of pad with 0.

* ir_to_mesa: Implement ir_binop_all_equal using DP4 w/SGEIan Romanick2011-08-161-1/+12
| | | | | | | | | | | | | | | | | | | The operation ir_binop_all_equal is !(a.x != b.x || a.y != b.y || a.z != b.z || a.w != b.w). Logical-or is implemented using addition (followed by clampling to [0,1]) on values of 0.0 and 1.0. Replacing the logical-or operators with addition gives !bool((int(a.x != b.x) + int(a.y == b.y) + int(a.z == b.z) + int(a.w == b.w)). This can be implemented using a dot-product with a vector of all 1.0. After the dot-product, the value will be an integer on the range [0,4]. Previously a SEQ instruction was used to clamp the resulting logic value to [0,1] and invert the result. Using an SGE instruction on the negation of the dot-product result has the same effect. Many older shader architectures do not support the SEQ instruction. It must be emulated using two SGE instructions and a MUL. On these architectures, the single SGE saves two instructions.

| | | | | | | | | | | | | | | | | | | | | | This is just like the ir_binop_logic_or case. The operation ir_unop_any is (a.x || a.y || a.z || a.w). Logical-or is implemented using addition (followed by clampling to [0,1]) on values of 0.0 and 1.0. Replacing the logical-or operators with addition gives (a.x + a.y + a.z + a.w). This can be implemented using a dot-product with a vector of all 1.0. Previously a SNE instruction was used to clamp the resulting logic value to [0,1]. In a fragment shader, using a saturate on the dot-product has the same effect. Adding the saturate to the dot-product is free, so (at least) one instruction is saved. In a vertex shader, using an SLT on the negation of the dot-product result has the same effect. Many older shader architectures do not support the SNE instruction. It must be emulated using two SLT instructions and an ADD. On these architectures, the single SLT saves two instructions. Reviewed-by: Eric Anholt <[email protected]>
