// Intrinsic Functions //
// //
// The intrinsic function declarations below declare all the built-in //
// functions supported by the WGSL language. This intrinsic definition //
// language supports simple static-type function declarations, as well as //
// single overload declarations that can match a number of different //
// argument types via the use of 'open-types' and 'open-numbers'. //
// //
// * Basic example: //
// //
// fn isInf(f32) -> bool //
// //
// Declares an overload of the function 'isInf' that accepts a single //
// parameter of type 'f32' and returns a 'bool'. //
// //
// An 'open-type' can be thought as a template type that is determined by the //
// arguments to the intrinsic. //
// //
// * Open-type example without constraint: //
// //
// fn arrayLength<T>(array<T>) -> u32 //
// //
// Declares an overload of the function 'arrayLength' that accepts a //
// single argument of an array type with no constraints on the array //
// element type. This overload will always return a value of the same type //
// as its single argument. //
// //
// * Open-type example with constraint: //
// //
// fn abs<T: fiu32>(T) -> T //
// //
// Declares an overload of the function 'abs' that accepts a single //
// argument of type 'f32', 'i32' or 'u32', which returns a value of the //
// same argument type. //
// //
// Similarly an 'open-number' can be thought as a template number or //
// enumerator that is determined by the arguments to the intrinsic. //
// //
// * Open-number example: //
// //
// fn dpdx<N: num>(vec<N, f32>) -> vec<N, f32> //
// //
// Declares an overload of the function 'dpdx' that accepts a single //
// argument of a variable-sized vector of 'f32', which returns a value of //
// the same argument type. //
// //
// //
// Matching algorithm: //
// ------------------- //
// //
// Prior to matching an overload, all open-types are undefined. //
// //
// Open-types become closed-types (pinned to a fixed type) on the first //
// attempt to match an argument to that open-type. //
// Once open-types are closed, they remain that type for the rest of the //
// overload evaluation. //
// //
// To better understand, let's consider the following hypothetical overload //
// declaration: //
// //
// fn foo<T: scalar>(T, T); //
// //
// T - is the open-type //
// scalar - is a matcher for the types 'f32', 'i32', 'u32' or 'bool' //
// (declared above) //
// <T: scalar> - declares the open-type T, with the constraint that T must //
// match one of 'f32', 'i32', 'u32' or 'bool'. //
// //
// The process for resolving this overload is as follows: //
// //
// (1) The overload resolver begins by attempting to match the argument //
// types from left to right. //
// The first parameter type is compared against the argument type. //
// As the open-type T has not been closed yet, T is closed as the type //
// of the first argument. //
// There's no verification that the T type is a scalar at this stage. //
// (2) The second parameter is then compared against the second argument. //
// As the open-type T is now closed, the argument type is compared //
// against the value of the closed-type of T. If the types match, then //
// the overload is still a candidate for matching, otherwise the //
// overload is no longer considered. //
// (3) If all the parameters matched, constraints on the open-types need //
// to be checked next. If the closed-type does not match the 'match' //
// constraint, then the overload is no longer considered. //
// //
// The algorithm for matching open-numbers is almost identical to open-types, //
// except of course, they match against integer numbers or enumerators //
// instead of types. //
// //
// //
// * More examples: //
// //
// fn F() //
// - Function called F. //
// No open types or numbers, no parameters, no return value //
// //
// fn F() -> RETURN_TYPE //
// - Function with RETURN_TYPE as the return type value //
// //
// fn F(f32, i32) //
// - Two fixed-type, anonymous parameters //
// //
// fn F(USAGE : f32) //
// - Single parameter with name USAGE. //
// Note: Parameter names are used by Tint to infer parameter order for //
// some intrinsic functions //
// //
// fn F<T>(T) //
// - Single parameter of unconstrained open-type T (any type) //
// //
// fn F<T: scalar>(T) //
// - Single parameter of constrained open-type T (must be a scalar) //
// //
// fn F<T: fiu32>(T) -> T //
// - Single parameter of constrained open-type T (must be a one of fiu32) //
// Return type matches parameter type //
// //
// fn F<T, N: num>(vec<N, T>) //
// - Single parameter of vector type with open-number size N and element //
// open-type T //
// //
// fn F<A: access>(texture_storage_1d<f32_texel_format, A>) //
// - Single parameter of texture_storage_1d type with open-number //
// access-control C, and of a texel format that is listed in //
// f32_texel_format //
// //
