+// Symbol table for parsing. Has these design characteristics:
+//
+// * Same symbol table can be used to compile many shaders, to preserve
+// effort of creating and loading with the large numbers of built-in
+// symbols.
+//
+// * Name mangling will be used to give each function a unique name
+// so that symbol table lookups are never ambiguous. This allows
+// a simpler symbol table structure.
+//
+// * Pushing and popping of scope, so symbol table will really be a stack
+// of symbol tables. Searched from the top, with new inserts going into
+// the top.
+//
+// * Constants: Compile time constant symbols will keep their values
+// in the symbol table. The parser can substitute constants at parse
+// time, including doing constant folding and constant propagation.
+//
+// * No temporaries: Temporaries made from operations (+, --, .xy, etc.)
+// are tracked in the intermediate representation, not the symbol table.

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 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. +// + +int __constructor (const float f) { + int i; + __asm float_to_int i, f; + return i; +} + +bool __constructor (const int i) { + return i != 0;
