Olli Etuaho a2d53039 2015-04-15T14:14:44 Disallow ternary operator on arrays and structs ESSL specs only allow a limited number of operators on arrays and structs. The spec section on the ternary operator contradicts this to an extent, saying that the second and third operands can be "any type" or "any type other than an array", but we interpret the spec so that the operator restrictions on structures and arrays override this.

Olli Etuaho 5290174b 2015-04-15T13:42:45 Refactor ternary operator parsing Refactor ternary operator parsing so that validation is done in ParseContext and Intermediate's role is simply to create the node added to the tree. Remove partially bugged checks for null nodes as a part of this - in error cases the parser doesn't typically add null nodes to the tree, but rather always has a fallback to add a dummy node if parsing fails as a method of recovery. When parsing ternary operators it should be guaranteed that none of the parameter nodes is null. Includes a better explanation of why ternary operators are not always folded when only the condition is constant, and a test to make sure this doesn't regress.

Olli Etuaho 376f1b5d 2015-04-13T13:23:41 Add support for implicit array size ESSL3 introduces implicit array size that is determined automatically according to the initializer. Implicit sizes are resolved when parsing constructors and when initializers are evaluated, so ANGLE's AST will not contain implicit sizes. Declarations where there are two differently sized arrays with the same implicitly sized type, for example: float[] a = float[](0.0), b = float[](0.0, 1.0); will be transformed into declarations where the two arrays don't share the array size like this: float a[1] = float[1](0.0), float b[2] = float[2](0.0, 1.0); so they are not a problem. Unlike sized arrays, implicitly sized arrays don't have a size limit enforced by the parser. Include a test that verifies that non-initialization of an implicitly sized array defined using ESSL3 type syntax is caught by the parser.

Olli Etuaho 2935c581 2015-04-08T14:32:06 Simplify code related to variable declaration Rename nonInitErrorCheck to declareVariable to clarify that it declares variables. Merge arrayErrorCheck with that so that logic that is common between array and non-array declarations is only in one place. This will simplify adding array initializer handling. This also enables redeclaring gl_LastFragData using ESSL3 array type syntax. Comments in executeInitializer claimed that the TVariable object was needed for error recovery, but that was not actually true, so it can also use the new declareVariable method. Make "variable" a local variable instead of a parameter to executeInitializer, since the parameter was never used by callers of the function.

Only keep the check inside arrayQualifierErrorCheck(). Second, ESSL3 will introduce array initializers and by extension constant arrays, so it should allow const qualifier on arrays. These checks are somewhat superfluous in ESSL1 as well, since the parser already checks for missing initializers, but it's useful to keep the informative error messages around. Add a few tests to make sure that when the ESSL3 implementation progresses, it still checks for missing initializers on constant arrays.

Jamie Madill 9b82084f 2015-02-12T10:40:10 Fix HLSL varying struct linking. We would always expand a struct name to always include its symbol ID. This fixes the workaround to only affect scoped structs. We can leave global structs, which are by definition uniquely named, without decorating them with a symbol ID. This fixes several tests in dEQP's shader.linkage.varying.struct. Re-land with GLSL translator bug fixed.

Jamie Madill 489ffc4d 2015-02-11T16:33:07 Allow varying structs to match between stages. We would always expand a struct name to always include its symbol ID. This workaround fixed scoped structs with the same name. It would also block any possiblity of linking the structs successfully. Instead we can use the workaround only on inner-scoped structs, and leave global structs, which are by definition uniquely named, as they are. This fixes several tests in dEQP's shader.linkage.varying.struct.
