30 // This class defines a Type lattice. The lattice is used in the constant | |
31 // propagation algorithms, and for some type-checking of the iloc code. | |
32 // Basic types include RSD's (lower bound, upper bound, stride for integers), | |
33 // float & double precision constants, sets of data-labels and code-labels. | |
34 // The complete lattice is described below. Subtypes have no relationship to | |
35 // up or down in the lattice; that is entirely determined by the behavior of | |
36 // the MEET/JOIN functions. | |
