* glsl: Add a lowering pass to handle advanced blending modes.Kenneth Graunke2016-08-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many GPUs cannot handle GL_KHR_blend_equation_advanced natively, and need to emulate it in the pixel shader. This lowering pass implements all the necessary math for advanced blending. It fetches the existing framebuffer value using the MESA_shader_framebuffer_fetch built-in variables, and the previous commit's state var uniform to select which equation to use. This is done at the GLSL IR level to make it easy for all drivers to implement the GL_KHR_blend_equation_advanced extension and share code. Drivers need to hook up MESA_shader_framebuffer_fetch functionality: 1. Hook up the fb_fetch_output variable 2. Implement BlendBarrier() Then to get KHR_blend_equation_advanced, they simply need to: 3. Disable hardware blending based on ctx->Color._AdvancedBlendEnabled 4. Call this lowering pass. Very little driver specific code should be required. v2: Handle multiple output variables per render target (which may exist due to ARB_enhanced_layouts), and array variables (even with one render target, we might have out vec4 color[1]), and non-vec4 variables (it's easier than finding spec text to justify not handling it). Thanks to Francisco Jerez for the feedback. v3: Lower main returns so that we have a single exit point where we can add our blending epilogue (caught by Francisco Jerez).

* nir: Add an IO scalarizing pass using the intrinsic's first_component.Eric Anholt2016-08-191-0/+1
| | | | | | | | | | vc4 wants to have per-scalar IO load/stores so that dead code elimination can happen on a more granular basis, which it has been doing in the backend using a multiplication by 4 of the intrinsic's driver_location. We can represent it properly in the NIR using the first_component field, though. Reviewed-by: Kenneth Graunke <[email protected]>

* nir: Add a pass for propagating invariant decorationsJason Ekstrand2016-06-201-0/+1
| | | | | | | | | | This pass is similar to propagate_invariance in the GLSL compiler. The real "output" of this pass is that any algebraic operations which are eventually consumed by an invariant variable get marked as "exact".

* nir: Add a simple nir_lower_wpos_center() pass for Vulkan drivers.Kenneth Graunke2016-05-201-0/+1
| | | | | | | | | | | | | | | | | | | | nir_lower_wpos_ytransform() is great for OpenGL, which allows applications to choose whether their coordinate system's origin is upper left/lower left, and whether the pixel center should be on integer/half-integer boundaries. Vulkan, however, has much simpler requirements: the pixel center is always half-integer, and the origin is always upper left. No coordinate transform is needed - we just need to add <0.5, 0.5>. This means that we can avoid using (and setting up) a uniform. I thought about adding more options to nir_lower_wpos_ytransform(), but making a new pass that never even touched uniforms seemed simpler. v2: Use normal iterator rather than _safe variant (noticed by Matt).

* nir: lower-io-types passRob Clark2016-05-111-0/+1
| | | | | | | | | | | | | | | | | A pass to lower complex (struct/array/mat) inputs/outputs to primitive types. This allows, for example, linking that removes unused components of a larger type which is not indirectly accessed. In the near term, it is needed for gallium (mesa/st) support for NIR, since only used components of a type are assigned VBO slots, and we otherwise have no way to represent that to the driver backend. But it should be useful for doing shader linking in NIR. v2: use glsl_count_attribute_slots() rather than passing a type_size fxn pointer Signed-off-by: Rob Clark <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
