* glsl: lower SSBO atomic intrinsicsIago Toral Quiroga2015-09-251-0/+159
| | | | | | | | | | | | | 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.

* glsl: use ir_rvalue instead of ir_dereference in auxiliary functionsSamuel Iglesias Gonsalvez2015-09-251-4/+4
| | | | | | | | | | In a later commit we will need to handle ir_swizzle nodes too, which are not an ir_dereference. That can happen, for example, when we pass a component of an integer vector as argument to any of the SSBO atomic functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
