* compiler/nir: add a lowering pass to convert the bit size of ALU operationsIago Toral Quiroga2018-05-031-0/+1
| | | | | | | | | | | | | | | | Not all bit-sizes may be supported natively in hardware for all operations. This pass allows drivers to lower such operations to a bit-size that is actually supported and then converts the result back to the original bit-size. Compiler backends control which operations and wich bit-sizes require the lowering through a callback function. v2: generalize this pass and make it available in NIR core (Rob, Jason) v3: remove some temporaries and reduce nesting in instruction loop using a continue statement (Jason) Reviewed-by: Jason Ekstrand <[email protected]>

INVALID_VALUE is generated if any element of <pConstantIndex> refers to a specialization constant that does not exist in the shader module contained in <shader>."" v2: rebase update (spirv_to_nir options added, changes on the warning logging, and others) v3: include passing options on common initialization, doesn't call setjmp on common_initialization v4: (after Jason comments): * Rename common_initialization to vtn_builder_create * Move validation method and their helpers to own source file. * Create own handle_constant_decoration_cb instead of reuse existing one v5: put vtn_build_create refactoring to their own patch (Jason) v6: update after vtn_builder_create method renamed, add explanatory comment, tweak existing comment and commit message (Timothy)
* nir: mako all the intrinsicsRob Clark2018-03-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | I threatened to do this a long time ago.. I probably *should* have done it a long time ago when there where many fewer intrinsics. But the system of macro/#include magic for dealing with intrinsics is a bit annoying, and python has the nice property of optional fxn params, making it possible to define new intrinsics while ignoring parameters that are not applicable (and naming optional params). And not having to specify various array lengths explicitly is nice too. I think the end result makes it easier to add new intrinsics. v2: couple small fixes found with a test program to compare the old and new tables v3: misc comments, don't rely on capture=true for meson.build, get rid of system_values table to avoid return value of intrinsic() and *mostly* remove side-effects, add autotools build support v4: scons build Signed-off-by: Rob Clark <[email protected]> Acked-by: Dylan Baker <[email protected]> Acked-by: Jason Ekstrand <[email protected]>

* glsl: fix derived cs variablesIlia Mirkin2017-10-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are two issues with the current implementation. First, it relies on the layout(local_size_*) happening in the same shader as the main function, and secondly it doesn't work for variable group sizes. In both cases, the simplest fix is to move the setup of these derived values to a later time, similar to how the gl_VertexID workarounds are done. There already exist system values defined for both of the derived values, so we use them unconditionally, and lower them after linking is performed. While we're at it, we move to using gl_LocalGroupSizeARB instead of gl_WorkGroupSize for variable group sizes. Also the dead code elimination avoidance can be removed, since there can be situations where gl_LocalGroupSizeARB is needed but has not been inserted for the shader with main function. As a result, the lowering code has to insert its own copies of the system values if needed.

* nir: Add a pass for moving SPIR-V continue blocks to the ends of loopsJason Ekstrand2016-12-221-0/+1
| | | | | | | | | | | | | | | When shaders come in from SPIR-V, we handle continue blocks by placing the contents of the continue inside of a "if (!first_iteration)". We do this so that we can properly handle the fact that continues in SPIR-V jump to the continue block at the end of the loop rather than jumping directly to the top of the loop like they do in NIR. In particular, the increment step of a simple for loop ends up in the continue block. This pass looks for this case in loops that don't actually have any continues and moves the continue contents to the end of the loop instead. We need this because loop unrolling doesn't work if the increment is inside of a condition. Reviewed-by: Timothy Arceri <[email protected]>
