Detailed Description

A tree node can represent a data type, a variable, an expression
or a statement.  Each node has a TREE_CODE which says what kind of
thing it represents.  Some common codes are:
INTEGER_TYPE -- represents a type of integers.
ARRAY_TYPE -- represents a type of pointer.
VAR_DECL -- represents a declared variable.
INTEGER_CST -- represents a constant integer value.
PLUS_EXPR -- represents a sum (an expression).

As for the contents of a tree node: there are some fields
that all nodes share.  Each TREE_CODE has various special-purpose
fields as well.  The fields of a node are never accessed directly,
always through accessor macros.   

Every kind of tree node starts with this structure,
so all nodes have these fields.

See the accessor macros, defined below, for documentation of the
fields, and the table below which connects the fields and the
accessor macros.
