The internal representation for expressions is for the most part quite
value of the expression is the value of the last sub-statement in the
@code{COMPOUND_STMT}.
+@item LOOP_EXPR
+These nodes represent ``infinite'' loops. The @code{LOOP_EXPR_BODY}
+represents the body of the loop. It should be executed forever, unless
+an @code{EXIT_EXPR} is encountered.
+
+@item EXIT_EXPR
+These nodes represent conditional exits from the nearest enclosing
+@code{LOOP_EXPR}. The single operand is the condition; if it is
+non-zero, then the loop should be exited. An @code{EXIT_EXPR} will only
+appear within a @code{LOOP_EXPR}.

@item CONSTRUCTOR
These nodes represent the brace-enclosed initializers for a structure or
array. The first operand is reserved for use by the back-end. The
