* glsl: Add ir_var_shader_storageKristian Høgsberg2015-07-141-0/+3
| | | | | | | | | | | This will be used to identify buffer variables inside shader storage buffer objects, which are very similar to uniforms except for a few differences, most important of which is that they are writable. Since buffer variables are so similar to uniforms, we will almost always want them to go through the same paths as uniforms. Reviewed-by: Jordan Justen <[email protected]>
* glsl: remove element_type() helperTimothy Arceri2015-05-221-2/+2
| | | | | | | | | | | | | | We now have is_array() and without_array() that make the code much clearer and remove the need for this. For all remaining calls to this we already knew that the type was an array so returning a null wasn't adding any value. v2: use without_array() in _mesa_ast_array_index_to_hir() and don't use without_array() in lower_clip_distance_visitor() as we want to make sure the array is 2D.

| | | | | | | | | | | | | | | | | | | | | | The i965 MUL instruction doesn't natively support 32-bit by 32-bit integer multiplication; additional instructions (MACH/MOV) are required. However, we can avoid those if we know one of the operands can be represented in 16 bits or less. The vector backend's is_16bit_constant static helper function checks for this. We want to be able to use it in the scalar backend as well, which means moving the function to a more generally-usable location. Since it isn't i965 specific, I decided to make it an ir_constant method, in case it ends up being useful to other people as well. v2: Rename from is_16bit_integer_constant to is_uint16_constant, as suggested by Ilia Mirkin. Update comments to clarify that it does apply to both int and uint types, as long as the value is non-negative and fits in 16-bits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling function calls, we often want to walk through the list of formal parameters and list of actual parameters at the same time. (Both are guaranteed to be the same length.) Previously, we used a pattern of: exec_list_iterator 1st_iter = <1st list>.iterator(); foreach_iter(exec_list_iterator, 2nd_iter, <2nd list>) { ... 1st_iter.next(); } This was awkward, since you had to manually iterate through one of the two lists.

| | | | | | | | | | | | | | | This patch creates a new generic is_value() method, which checks if an ir_constant has a particular value. (For vectors, it must have the single value repeated across all components.) It then rewrites the is_zero/is_one/is_negative_one methods to use this generic helper. All three were basically identical except for the value they checked for. The other difference is that is_negative_one rejects boolean types. The new is_value function maintains this behavior, only allowing boolean types when checking for 0 or 1.

Further, if var->type->is_array() is true, we have a related implicit invariant: var->type->fields.array->is_interface() == (var->type->fields.array == var->interface_type) However, the ir_variable constructor doesn't maintain either invariant. That seems kind of silly... and I tripped over it while writing some other code.
