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

+//
+// 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 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.
