Detailed Description

Enumeration type.

We use the following representation for enums:

• the Enum_symbol is just a symbol-table placeholder to represent the type.
• the individual enumerators are Variable_symbol's without address.
• each of the enumerators is initialized with "0" (first one) or "previous_enum + 1" unless it is already initialized explicitly.
