-// 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 destination and 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.
-//
-
-//
-// TODO:
-// - do something with [] operator: leave it in compiler or move it here,
-// - emulate bools and ints with floats (this should simplify target implementation),
-// - are vec*mat and mat*vec definitions correct? is the list complete?

-// type of the object being constructed, the scalar construction rules (above) are used to convert
-// the parameters.

-// 5.8 Assignments
-//
-// Assignments of values to variable names are done with the assignment operator ( = ), like
-//
-// lvalue = expression
-//
-// The assignment operator stores the value of expression into lvalue. It will compile only if
-// expression and lvalue have the same type. All desired type-conversions must be specified
-// explicitly via a constructor. Lvalues must be writable. Variables that are built-in types,
-// entire structures, structure fields, l-values with the field selector ( . ) applied to select
-// components or swizzles without repeated fields, and l-values dereferenced with the array
-// subscript operator ( [ ] ) are all possible l-values. Other binary or unary expressions,
-// non-dereferenced arrays, function names, swizzles with repeated fields, and constants cannot
-// be l-values.
-//
-// Expressions on the left of an assignment are evaluated before expressions on the right of the
-// assignment.

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 destination and 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.
