2015-07-09glsl: Consider active all elements of a shared/std140 block arrayAntia Puentes1-0/+23
Commmit 1ca25ab (glsl: Do not eliminate 'shared' or 'std140' blocks or block members) considers active 'shared' and 'std140' uniform blocks and uniform block arrays but did not include the block array elements. It was possible to have an active uniform block array without any elements marked as used, making the assertion ((b->num_array_elements > 0) == b->type->is_array()) in link_uniform_blocks fail. Fixes the following 5 dEQP tests: * dEQP-GLES3.functional.ubo.random.nested_structs_instance_arrays.18 * dEQP-GLES3.functional.ubo.random.nested_structs_instance_arrays.24 * dEQP-GLES3.functional.ubo.random.nested_structs_arrays_instance_arrays.19 * dEQP-GLES3.functional.ubo.random.all_per_block_buffers.49 * dEQP-GLES3.functional.ubo.random.all_shared_buffer.36

2015-07-09glsl: Do not allow reads from write-only variablesIago Toral Quiroga1-0/+49
The error location won't be right, but fixing that would require to check for this as we process each type of AST node that can involve a variable read.

2015-07-09glsl: Allow memory layout qualifiers on shader storage buffer objectsIago Toral Quiroga2-5/+101
Since memory qualifiers are also keywords we need to do the same trick we use for other keywords that can be used as layout qualifiers to handle alternate capitalizations in desktop GLSL, like row_major, etc.

2015-07-09glsl: lower SSBO atomic intrinsicsIago Toral Quiroga1-0/+141
The first argument to SSBO atomics is a reference to a SSBO buffer variable so we want to compute its block index and offset and provide these values to an internal version of the intrinsic that takes them instead of the buffer variable reference.

We need our reads to provide well-defined results for all enabled channels even for helper invocations, which means that we should not use a pixel mask with them.

2015-07-09glsl: propagate std430 packing qualifier to struct's members and array of ↵Samuel Iglesias Gonsalvez4-52/+106
structs When propagating std430 packing qualifier to the struct's members, new glsl_types need to be created because the existing ones are const. The new glsl_types are meant to replace the already defined one taking into account that the field names cannot have different names as it is the same struct definition but with different packing. This patch is designed to keep previous default behavior (use std140 as interface packing qualifier) when there is no std430 interface packing. In order to facilitate the task, the glsl_type constructors for struct and for interfaces are unified, as they had the same code but different base_type.

Otherwise we can expect odd things to happen if, for example, we ask for the size of the attached buffer from shader code, since that might query this value from the surface we uploaded and get random results. Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com>

2015-07-09glsl: Add parser/compiler support for unsized array's length()Samuel Iglesias Gonsalvez9-6/+75
It also creates unop and triop expressions to tell the driver to calculate the unsized array length. It is needed two expressions to do the calculation: * The unop expression saves the ir_rvalue* whose length should be calculated. * Afterwards, this unop is going to be processed by a lowering pass that will convert it to a triop that includes the block index, offset of the variable inside the shader storage block and the array stride. All of them are needed for length() calculation following GL_ARB_shader_storage_buffer spec: array.length() = max((buffer_object_size - offset_of_array) / stride_of_array, 0) Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com>
