-// This file defines nearly all constructors and operators for built-in data types, using
-// extended language syntax. In general, compiler treats constructors and operators as
-// ordinary functions with some exceptions. For example, the language does not allow
-// functions to be called in constant expressions - here the exception is made to allow it.
-//
-// Each implementation provides its own version of this file. Each implementation can define
-// the required set of operators and constructors in its own fashion.
-//
-// The extended language syntax is only present when compiling this file. It is implicitly
-// included at the very beginning of the compiled shader, so no built-in functions can be
-// used.
-//
-// To communicate with the implementation, a special extended "__asm" keyword is used, followed
-// by an instruction name (any valid identifier), a destination variable identifier and a
-// a list of zero or more source variable identifiers. A variable identifier is a variable name
-// declared earlier in the code (as a function parameter, local or global variable).
-// An instruction name designates an instruction that must be exported by the implementation.
-// Each instruction receives data from source variable identifiers and returns data in the
-// destination variable identifier.
-//
-// It is up to the implementation how to define a particular operator or constructor. If it is
-// expected to being used rarely, it can be defined in terms of other operators and constructors,
-// for example:
-//
-// ivec2 __operator + (const ivec2 x, const ivec2 y) {
-//    return ivec2 (x[0] + y[0], x[1] + y[1]);
-// }
-//
-// If a particular operator or constructor is expected to be used very often or is an atomic
-// operation (that is, an operation that cannot be expressed in terms of other operations or
-// would create a dependency cycle) it must be defined using one or more __asm constructs.
-//
-// Each implementation must define constructors for all scalar types (bool, float, int).
-// There are 9 scalar-to-scalar constructors (including identity constructors). However,
-// since the language introduces special constructors (like matrix constructor with a single
-// scalar value), implementations must also implement these cases.
-// The compiler provides the following algorithm when resolving a constructor:
-// - try to find a constructor with a prototype matching ours,
-// - if no constructor is found and this is a scalar-to-scalar constructor, raise an error,
-// - if a constructor is found, execute it and return,
-// - count the size of the constructor parameter list - if it is less than the size of
-//   our constructor's type, raise an error,
-// - for each parameter in the list do a recursive constructor matching for appropriate
-//   scalar fields in the constructed variable,
-//
-// Each implementation must also define a set of operators that deal with built-in data types.
-// There are four kinds of operators:
-// 1) Operators that are implemented only by the compiler: "()" (function call), "," (sequence)
-//    and "?:" (selection).
-// 2) Operators that are implemented by the compiler by expressing it in terms of other operators:
-//    - "." (field selection) - translated to subscript access,
-//    - "&&" (logical and) - translated to "<left_expr> ? <right_expr> : false",
-//    - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
-// 3) Operators that can be defined by the implementation and if the required prototype is not
-//    found, standard behaviour is used:
-//    - "==", "!=", "=" (equality, assignment) - compare or assign matching fields one-by-one;
-//      note that at least operators for scalar data types must be defined by the implementation
-//      to get it work,
-// 4) All other operators not mentioned above. If no required prototype is found, an error is
-//    raised. An implementation must follow the language specification to provide all valid
-//    operator prototypes.

+//
+// This file defines nearly all constructors and operators for built-in data types, using
+// extended language syntax. In general, compiler treats constructors and operators as
+// ordinary functions with some exceptions. For example, the language does not allow
+// functions to be called in constant expressions - here the exception is made to allow it.
+//
+// Each implementation provides its own version of this file. Each implementation can define
+// the required set of operators and constructors in its own fashion.
+//
+// The extended language syntax is only present when compiling this file. It is implicitly
+// included at the very beginning of the compiled shader, so no built-in functions can be
+// used.
+//
+// To communicate with the implementation, a special extended "__asm" keyword is used, followed
+// by an instruction name (any valid identifier), a destination variable identifier and a
+// a list of zero or more source variable identifiers. A variable identifier is a variable name
+// declared earlier in the code (as a function parameter, local or global variable).
+// An instruction name designates an instruction that must be exported by the implementation.
+// Each instruction receives data from source variable identifiers and returns data in the
+// destination variable identifier.
+//
+// It is up to the implementation how to define a particular operator or constructor. If it is
+// expected to being used rarely, it can be defined in terms of other operators and constructors,
+// for example:
+//
+// ivec2 __operator + (const ivec2 x, const ivec2 y) {
+//    return ivec2 (x[0] + y[0], x[1] + y[1]);
+// }
+//
+// If a particular operator or constructor is expected to be used very often or is an atomic
+// operation (that is, an operation that cannot be expressed in terms of other operations or
+// would create a dependency cycle) it must be defined using one or more __asm constructs.
+//
+// Each implementation must define constructors for all scalar types (bool, float, int).
+// There are 9 scalar-to-scalar constructors (including identity constructors). However,
+// since the language introduces special constructors (like matrix constructor with a single
+// scalar value), implementations must also implement these cases.
+// The compiler provides the following algorithm when resolving a constructor:
+// - try to find a constructor with a prototype matching ours,
+// - if no constructor is found and this is a scalar-to-scalar constructor, raise an error,
+// - if a constructor is found, execute it and return,
+// - count the size of the constructor parameter list - if it is less than the size of
+//   our constructor's type, raise an error,
+// - for each parameter in the list do a recursive constructor matching for appropriate
+//   scalar fields in the constructed variable,
+//
+// Each implementation must also define a set of operators that deal with built-in data types.
+// There are four kinds of operators:
+// 1) Operators that are implemented only by the compiler: "()" (function call), "," (sequence)
+//    and "?:" (selection).
+// 2) Operators that are implemented by the compiler by expressing it in terms of other operators:
+//    - "." (field selection) - translated to subscript access,
+//    - "&&" (logical and) - translated to "<left_expr> ? <right_expr> : false",
+//    - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
+// 3) Operators that can be defined by the implementation and if the required prototype is not
+//    found, standard behaviour is used:
+//    - "==", "!=", "=" (equality, assignment) - compare or assign matching fields one-by-one;
+//      note that at least operators for scalar data types must be defined by the implementation
+//      to get it work,
+// 4) All other operators not mentioned above. If no required prototype is found, an error is
+//    raised. An implementation must follow the language specification to provide all valid
+//    operator prototypes.
