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. +// + + + +//// Basic, scalar constructors/casts + +int __constructor(const float f) +{ + __asm vec4_to_ivec4 __retVal, f;
