1 11.2.1 Trees
1 ------------
1
1 All GENERIC trees have two fields in common. First, 'TREE_CHAIN' is a
1 pointer that can be used as a singly-linked list to other trees. The
1 other is 'TREE_TYPE'. Many trees store the type of an expression or
1 declaration in this field.
1
1 These are some other functions for handling trees:
1
1 'tree_size'
1 Return the number of bytes a tree takes.
1
1 'build0'
1 'build1'
1 'build2'
1 'build3'
1 'build4'
1 'build5'
1 'build6'

1 These functions build a tree and supply values to put in each
1 parameter. The basic signature is 'code, type, [operands]'.
1 'code' is the 'TREE_CODE', and 'type' is a tree representing the
1 'TREE_TYPE'. These are followed by the operands, each of which is
1 also a tree.
