/* Switch expression.
TREE_TYPE is the original type of the condition, before any
language required type conversions. It may be NULL, in which case
the original type and final types are assumed to be the same.
Operand 0 is the expression used to perform the branch,
Operand 1 is the body of the switch, which probably contains
CASE_LABEL_EXPRs. It may also be NULL, in which case operand 2
must not be NULL. */

/* Used to represent a case label.
Operand 0 is CASE_LOW. It may be NULL_TREE, in which case the label
is a 'default' label.
Operand 1 is CASE_HIGH. If it is NULL_TREE, the label is a simple
(one-value) case label. If it is non-NULL_TREE, the case is a range.
Operand 2 is CASE_LABEL, which has the corresponding LABEL_DECL.
Operand 3 is CASE_CHAIN. This operand is only used in tree-cfg.cc to
speed up the lookup of case labels which use a particular edge in
the control flow graph. */
