Cоnsider а lаnguаge which defines types accоrding tо the following grammar: --> int8 | int32 | struct { } --> ; | ε --> ID : A struct is a collection of fields. The type of a field could, in turn, be a struct that is defined inline. Here is an example of a type definition according to the grammar above: struct { A : int32; B : struct { X : int8; Y : int8; };} The size of a type refers to the amount of memory occupied by an instance of the type. int8 and int32 are 8-bit and 32-bit integers, respectively. In this language, the size of a struct is the sum of the sizes of its fields. Construct an attribute grammar to compute the size of a . Define attributes and state if each attribute is synthetic or inherited. Write propagation rules for the attributes. Use the format: -> ==> .attribute1 = .attribute2 State how attributes are evaluated through traversing the parse tree. Using the example declarations for a and b above, show the derivations and how attributes are propagated through the parse tree. Use the format: 1. .attribute1 = .attribute2
