* glsl: rename _restrict to restrict_flagBrian Paul2014-02-121-2/+2
| | | | | | | | | | | To fix MSVC compile breakage. Evidently, _restrict is an MSVC keyword, though the docs only mention __restrict (with two underscores). Note: we may want to also rename _volatile to volatile_flag to be consistent. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=74900 Reviewed-by: Ian Romanick <[email protected]>

* glsl: Use a new foreach_two_lists macro for walking two lists at once.Kenneth Graunke2014-01-131-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 introduces a foreach_two_lists macro which safely walks through two lists at the same time, so you can simply do: foreach_two_lists(1st_node, <1st list>, 2nd_node, <2nd list>) { ... } v2: Rename macro from foreach_list2 to foreach_two_lists, as suggested by Ian Romanick.

* glsl: Refactor is_zero/one/negative_one into an is_value() method.Kenneth Graunke2014-01-071-68/+17
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From section 7.1 (Built-In Language Variables) of the GLSL 4.10 spec: Also, if a built-in interface block is redeclared, no member of the built-in declaration can be redeclared outside the block redeclaration. We have been regarding this text as a clarification to the behaviour established for gl_PerVertex by GLSL 1.50, so we apply it regardless of GLSL version. This patch enforces the rule by adding an enum to ir_variable to track how the variable was declared: implicitly, normally, or in an interface block.

| | | | | | | | | | | | | | | | | | I made this a function (instead of a method of ir_variable) because it made the change set smaller, and I expect that there will be an overload that takes an ir_var_mode enum.

* glsl: When constructing a variable with an interface type, set interface_typeIan Romanick2013-10-221-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ever since the addition of interface blocks with instance names, we have had an implicit invariant: var->type->is_interface() == (var->type == var->interface_type) The odd use of == here is intentional because !var->type->is_interface() implies var->type != var->interface_type. 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. This patch makes the constructor do the right thing, and it introduces some tests to verify that behavior. v2: Add general-ir-test to .gitignore.

| | | | | | | | | | | | | | | | | | | | | | | | For the upcoming built-in function rewrite, we'll need to be able to answer "Is this built-in function signature available?". This is actually a somewhat complex question, since it depends on the language version, GLSL vs. GLSL ES, enabled extensions, and the current shader stage. Storing such a set of constraints in a structure would be painful, so instead we store a function pointer. When creating a signature, we simply point to a predicate that inspects _mesa_glsl_parse_state and answers whether the signature is available in the current shader. Unfortunately, IR reader doesn't actually know when built-in functions are available, so this patch makes it lie and say that they're always present. This allows us to hook up the new functionality; it just won't be useful until real data is populated. In the meantime, the existing profile mechanism ensures built-ins are available in the right places.

| | | | | | | | | | | | | | | | | | | Previously, we had separate constructors for one, two, and four operand expressions. This patch consolidates them into a single constructor which uses NULL default parameters. The unary and binary operator constructors had assertions to verify that the caller supplied the correct number of operands for the expression, but the four-operand version did not. Since get_num_operands for ir_quadop_vector returns the number of vector_elements, we can safely add that without breaking the semantics of ir_quadop_vector.
