* i965/fs: Don't double-convert integer/boolean uniforms.Kenneth Graunke2011-08-191-16/+20
| | | | | | | | | | | | | When ctx->Const.NativeIntegers is set, Core Mesa loads integer/boolean uniforms directly, rather than loading the floating point equivalent. So, when that's set, we don't need to perform any conversions. Unfortunately, we can't properly support native integers with the old vertex shader backend, so this patch leaves them disabled for now.

* mesa, glsl_to_tgsi: Add new gl_context::NativeIntegers flag.Kenneth Graunke2011-08-193-27/+37
| | | | | | | | | | | | | | | | | | | Previously, native integer support was based on whether the driver advertised GLSL 1.30 or not. However, drivers that natively support integers may wish to do so for older GLSL versions as well. Adding this new opt-in flag allows them to do so. Currently disabled by default on all drivers, which was the existing behavior (no drivers currently implement GLSL 1.30). Fixes piglit tests on i965 with INTEL_GLSL_VERSION=130 set: - spec/glsl-1.10/fs-uniform-int-110.shader_test - spec/glsl-1.30/fs-uniform-int-130.shader_test (it was doubly converting the data) Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* i965/vs: Implement proper register allocation instead of 1:1 mapping.Eric Anholt2011-08-192-1/+155
| | | | | | Fixes vs-atan-* and several others. This is not the real solution we eventually want, which will pack floats, vec2s, and vec3s into vec4 registers, but this code should provide the framework for that.
* i965/vs: Add simple dead code elimination.Eric Anholt2011-08-193-0/+38
| | | | | This is copied right from the fragment shader. It is needed for real register allocation to work correctly.
* i965/vs: Copy the live intervals calculation over from the FS.Eric Anholt2011-08-194-0/+139
| | | | | | This is a rather pessimistic calculation, since it doesn't distinguish individual channels of a vec4, or elements of an array, but should be a minimum start for register allocation.

| | | | | This was copy'n'paste from the fragment shader, and didn't make sense here.

| | | | | | | | | | | Q should not be significant for OPCODE_TEX, but it winds up getting passed to the compute_lambda() function. Make sure it's 1.0 to prevent garbage values, which is effectively what we get when the swizzle is coord.xyzz (which is what GLSL gives us).

* 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.

| | | | | | | | | The operation ir_binop_any_nequal is (a.x != b.x) || (a.y != b.y) || (a.z != b.z) || (a.w != b.w), and that is the same as any(bvec4(a.x != b.x, a.y != b.y, a.z != b.z, a.w != b.w)).

| | | | | | | | | | | | | | | | | | | | | | 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]>

| | | | | | | | | | | | | | | | | | | Logical-or is implemented using addition (followed by clampling to [0,1]) on values of 0.0 and 1.0.
