* glsl: Apply memory qualifiers to buffer variablesIago Toral Quiroga2015-09-253-3/+91
| | | | | | | | | | | | v2: - Save memory qualifier info in the top level members of a shader storage block. - Add a checks to record_compare() which is used when comparing shader storage buffer declarations in different shaders. - Always report an error for incompatible readonly/writeonly definitions, whether they are present at block or field level.

| | | | | | | | | | | | | 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. v2: - Support single components of integer vectors to be passed in as arguments. - Get interface packing information from interface's type.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The unsized array length is computed with the following formula: array.length() = max((buffer_object_size - offset_of_array) / stride_of_array, 0) Of these, only the buffer size needs to be provided by the backends, the frontend already knows the values of the two other variables. This patch identifies the cases where we need to get the length of an unsized array, injecting ir_unop_ssbo_unsized_array_length expressions that will be lowered (in a later patch) to inject the formula mentioned above. It also adds the ir_unop_get_buffer_size expression that drivers will implement to provide the buffer length. v2: - Do not define a triop that will force backends to implement the entire formula, they should only need to provide the buffer size since the other values are known by the frontend (Curro). v3: - Call state->has_shader_storage_buffer_objects() in ast_function.cpp instead of using state->ARB_shader_storage_buffer_object_enable (Tapani).
