1// GLSL ES 1.0 does not allow *any* operators other than subscripting to be used with arrays, 2// or with structs containing arrays. SkSL (and later versions of GLSL) allow assignment and 3// equality for those types. This file tests operators that would be legal, but should be flagged 4// as errors. A related consequence (also tested here) is that functions can not return arrays, 5// or structs containing arrays. 6 7// Expect 17 errors 8 9struct S { int x[1]; }; // For "simple" case 10struct T { S s; }; // For trickier, nested case 11 12S s1, s2; 13T t1, t2; 14int a1[1]; int a2[1]; 15 16void assign_A() { a1 = a2; } 17void assign_S() { s1 = s2; } 18void assign_T() { t1 = t2; } 19 20// Note: No way to even write return_A() 21S return_S() { return s1; } 22T return_T() { return t1; } 23 24bool equals_A() { return a1 == a2; } 25bool equals_S() { return s1 == s2; } 26bool equals_T() { return t1 == t2; } 27 28bool notequals_A() { return a1 != a2; } 29bool notequals_S() { return s1 != s2; } 30bool notequals_T() { return t1 != t2; } 31 32void sequence_A() { a1, a2; } 33void sequence_S() { s1, s2; } 34void sequence_T() { t1, t2; } 35 36int ternary_A(bool b) { return (b ? a1 : a2) [0]; } 37int ternary_S(bool b) { return (b ? s1 : s2) .x[0]; } 38int ternary_T(bool b) { return (b ? t1 : t2).s.x[0]; } 39 40/*%%* 41operator '=' can not operate on arrays (or structs containing arrays) 42operator '=' can not operate on arrays (or structs containing arrays) 43operator '=' can not operate on arrays (or structs containing arrays) 44functions may not return structs containing arrays 45functions may not return structs containing arrays 46operator '==' can not operate on arrays (or structs containing arrays) 47operator '==' can not operate on arrays (or structs containing arrays) 48operator '==' can not operate on arrays (or structs containing arrays) 49operator '!=' can not operate on arrays (or structs containing arrays) 50operator '!=' can not operate on arrays (or structs containing arrays) 51operator '!=' can not operate on arrays (or structs containing arrays) 52operator ',' can not operate on arrays (or structs containing arrays) 53operator ',' can not operate on arrays (or structs containing arrays) 54operator ',' can not operate on arrays (or structs containing arrays) 55ternary operator result may not be an array (or struct containing an array) 56ternary operator result may not be an array (or struct containing an array) 57ternary operator result may not be an array (or struct containing an array) 58*%%*/ 59
