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;
