* python: Use range() instead of xrange()Mathieu Bridon2018-07-241-2/+2
| | | | | | | | | | | | | | | | Python 2 has a range() function which returns a list, and an xrange() one which returns an iterator. Python 3 lost the function returning a list, and renamed the function returning an iterator as range(). As a result, using range() makes the scripts compatible with both Python versions 2 and 3.

* python: Better use iteratorsMathieu Bridon2018-07-241-2/+2
| | | | | | | | | | | | | | | | | In Python 2, iterators had a .next() method. In Python 3, instead they have a .__next__() method, which is automatically called by the next() builtin. In addition, it is better to use the iter() builtin to create an iterator, rather than calling its __iter__() method. These were also introduced in Python 2.6, so using it makes the script compatible with Python 2 and 3.

* python: Better iterate over dictionariesMathieu Bridon2018-07-246-8/+8
| | | | | | | | | | | | | | | | In Python 2, dictionaries have 2 sets of methods to iterate over their keys and values: keys()/values()/items() and iterkeys()/itervalues()/iteritems(). The former return lists while the latter return iterators. Python 3 dropped the method which return lists, and renamed the methods returning iterators to keys()/values()/items(). Using those names makes the scripts compatible with both Python 2 and 3.

* nir: Do not use continue block after removing it.Bas Nieuwenhuizen2018-07-201-6/+25
| | | | | | | | | | | | | | | | Reinserting code directly before a jump means the block gets split and merged, removing the original block and replacing it in the process. Hence keeping a pointer to the continue block over a reinsert causes issues. This code changes nir_opt_if to simply look for the new continue block.

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

| | | | | | | | | | | | | | | | This pass searches for reasonably large local variables which can be statically proven to be constant and moves them into shader constant data. This is especially useful when large tables are baked into the shader source code because they can be moved into a UBO by the driver to reduce register pressure and make indirect access cheaper. v2 (Jason Ekstrand): - Use a size/align function to ensure we get the right alignments - Use the newly added deref offset helpers Reviewed-by: Timothy Arceri <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]> Reviewed-by: Kenneth Graunke <[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]>

* nir: fix selection of loop terminator when two or more have the same limitTimothy Arceri2018-06-302-4/+4
| | | | | | | | | | | | | | | | | 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. Because of the logic change we also switch some list access in the complex unrolling logic to avoid breakage.
