| // Builtin Functions // |
| // // |
| // The builtin function declarations below declare all the built-in // |
| // functions supported by the WGSL language. This builtin 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 template types and template 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'. // |
| // // |
| // A template type is a type determined by the arguments to the builtin. // |
| // // |
| // * Template 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. // |
| // // |
| // * Template 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 a template number is a number or enumerator that is determined // |
| // by the arguments to the builtin. // |
| // // |
| // * Template 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 for a single overload: // |
| // ----------------------------------------- // |
| // // |
| // The goal of matching is to compare a function call's arguments and any // |
| // explicitly provided template types in the program source against an // |
| // overload declaration in this file, and determine if the call satisfies // |
| // the form and type constraints of the overload. If the call matches an // |
| // overload, then the overload is added to the list of 'overload candidates' // |
| // used for overload resolution (described below). // |
| // // |
| // Prior to matching an overload, all template types are undefined. // |
| // // |
| // Template types are first defined with the type of the leftmost argument // |
| // that matches against that template type name. Subsequent arguments that // |
| // attempt to match against the template type name will either reject the // |
| // overload or refine the template, in one of 3 ways: // |
| // (a) Fail to match, causing the overload to be immediately rejected. // |
| // (b) Match the existing template type, either exactly or via implicit // |
| // conversion, and overload resolution continues. // |
| // (c) Match via implicit conversion of the currently defined template type // |
| // to the argument type. In this situation, the template type is refined // |
| // with the more constrained argument type, and overload resolution // |
| // continues. // |
| // // |
| // To better understand, let's consider the following hypothetical overload // |
| // declaration: // |
| // // |
| // fn foo<T: scalar>(T, T); // |
| // // |
| // T - is the template type name // |
| // scalar - is a matcher for the types 'f32', 'i32', 'u32' or 'bool' // |
| // (declared above) // |
| // <T: scalar> - declares the template 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 T. // |
| // As the template type T has not been defined yet, T is defined 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 template type T is now defined the argument type is compared // |
| // against the value of the defined type of T. Depending on the // |
| // comparison of the argument type to the template type, either the // |
| // actions of (a), (b) or (c) from above will occur. // |
| // (3) If all the parameters matched, constraints on the template types // |
| // need to be checked next. If the defined type does not match the // |
| // 'match' constraint, then the overload is no longer considered. // |
| // // |
| // This algorithm for matching a single overload is less general than the // |
| // algorithm described in the WGSL spec. But it makes the same decisions // |
| // because the overloads defined by WGSL are monotonic in the sense that once // |
| // a template parameter has been refined, there is never a need to backtrack // |
| // and un-refine it to match a later argument. // |
| // // |
| // The algorithm for matching template numbers is similar to matching // |
| // template types, except numbers need to exactly match across all uses - // |
| // there is no implicit conversion. Template numbers may match integer // |
| // numbers or enumerators. // |
| // // |
| // // |
| // Overload resolution for candidate overloads // |
| // ------------------------------------------- // |
| // // |
| // If multiple candidate overloads match a given set of arguments, then a // |
| // final overload resolution pass needs to be performed. The arguments and // |
| // overload parameter types for each candidate overload are compared, // |
| // following the algorithm described at: // |
| // https://www.w3.org/TR/WGSL/#overload-resolution-section // |
| // // |
| // If the candidate list contains a single entry, then that single candidate // |
| // is picked, and no overload resolution needs to be performed. // |
| // // |
| // If the candidate list is empty, then the call fails to resolve and an // |
| // error diagnostic is raised. // |
| // // |
| // // |
| // More examples // |
