* nir: Apply fragment color clamping to gl_FragData[] as well.Eric Anholt2018-07-051-7/+2
| | | | | | | | | | | | | | From the ARB_color_buffer_float spec: 35. Should the clamping of fragment shader output gl_FragData[n] be controlled by the fragment color clamp. RESOLVED: Since the destination of the FragData is a color buffer, the fragment color clamp control should apply. Fixes arb_color_buffer_float-mrt mixed on v3d.

* python: Stabilize some script outputsMathieu Bridon2018-07-052-2/+4
| | | | | | | | | | | | In Python, dictionaries and sets are unordered, and as a result their is no guarantee that running this script twice will produce the same output. Using ordered dicts and explicitly sorting items makes the build more reproducible, and will make it possible to verify that we're not breaking anything when we move the build scripts to Python 3.

* nir: Fix OpAtomicCounterIDecrement for uniform atomic countersAntia Puentes2018-07-035-9/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the SPIR-V 1.0 specification, section 3.32.18, "Atomic Instructions": "OpAtomicIDecrement: <skip> The instruction's result is the Original Value." However, we were implementing it, for uniform atomic counters, as a pre-decrement operation, as was the one available from GLSL. Renamed the former nir intrinsic 'atomic_counter_dec*' to 'atomic_counter_pre_dec*' for clarification purposes, as it implements a pre-decrement operation as specified for GLSL. From GLSL 4.50 spec, section 8.10, "Atomic Counter Functions": "uint atomicCounterDecrement (atomic_uint c) Atomically 1. decrements the counter for c, and 2. returns the value resulting from the decrement operation. These two steps are done atomically with respect to the atomic counter functions in this table." Added a new nir intrinsic 'atomic_counter_post_dec*' which implements a post-decrement operation as required by SPIR-V. v2: (Timothy Arceri) * Add extra spec quotes on commit message * Use "post" instead "pos" to avoid confusion with "position" Signed-off-by: Antia Puentes <[email protected]> Signed-off-by: Alejandro Piñeiro <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
* nir/linker: Add a pure NIR implementation of the atomic counter linkerNeil Roberts2018-07-034-0/+287
| | | | | | | | | | | | This is mostly just a straight-forward conversion of link_assign_atomic_counter_resources to C directly using nir variables instead of GLSL IR variables. It is based on the version of link_assign_atomic_counter_resources in 6b8909f2d1906. I’m noting this here to make it easier to track changes and keep the NIR version up-to-date.

| | | | | | | | | | | | | | | | | | | | When constructing NIR if we have a SPIR-V uint variable and the storage class is SpvStorageClassAtomicCounter, we store as NIR's glsl_type an atomic_uint to reflect the fact that the variable is an atomic counter.

* spirv/nir: tweak nir type when storage class is SpvStorageClassAtomicCounterAlejandro Piñeiro2018-07-031-1/+11
| | | | | | | | | | | | | GLSL types differentiates uint from atomic uint. On SPIR-V the type is uint, and the variable has a specific storage class. So we need to tweak the type based on the storage class. Ideally we would like to get the proper type at vtn_handle_type, but we don't have the storage class at that moment. We tweak only the nir type, as is the one that really requires it. Reviewed-by: Timothy Arceri <[email protected]>

* nir: Add a concept of constant data associated with a shaderJason Ekstrand2018-07-025-0/+30
| | | | | | | | | | | | | | | | | | | This commit adds a concept to NIR of having a blob of constant data associated with a shader. Instead of being a UBO or uniform that can be manipulated by the client, this constant data considered part of the shader and remains constant across all invocations of the given shader until the end of time. To access this constant data from the shader, we add a new load_constant intrinsic. The intention is that drivers will eventually lower load_constant intrinsics to load_ubo, load_uniform, or something similar. Constant data will be used by the optimization pass in the next commit but this concept may also be useful for OpenCL. v2 (Jason Ekstrand): - Rename num_constants to constant_data_size (anholt) Reviewed-by: Timothy Arceri <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | | | We need to add loop terminators to the list in the order we come across them otherwise if two or more have the same exit condition we will select that last one rather than the first one even though its unreachable. This fix is for simple unrolls where we only have a single exit point. When unrolling these type of loops the unreachable terminators and their unreachable branch are removed prior to unrolling.
