* glsl: Do not allow reads from write-only buffer variablesIago Toral Quiroga2015-09-251-0/+56
| | | | | | | | | | | | | 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. v2: - Limit the check to buffer variables, image variables have different semantics involved.

| | | | | | | | | | | v2: - Merge the error check for the readonly qualifier with the already existing check for variables flagged as readonly (Timothy). - Limit the check to buffer variables, image variables have different semantics involved (Curro).

| | | | | | | | v2: - Memory qualifiers on shader storage buffer objects do not come in the form of layout qualifiers, they are block-level qualifiers. Reviewed-by: Kristian Høgsberg <[email protected]>

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