Classes
| CongruentCopyInstruction | A CopyInstruction whose source operand’s value is congruent to the definition of that source operand. For example: Point p = { 1, 2 }; Point q = p; int a = p.x; The use of p on line 2 is linked to the definition of p on line 1, and is congruent to that definition because it accesses the exact same memory. The use of p.x on line 3 is linked to the definition of p on line 1 as well, but is not congruent to that definition because p.x accesses only a subset of the memory defined by p.

| LoadTotalOverlapInstruction | |
| TypePreservingConvertInstruction | A ConvertInstruction which converts data of type T to data of type U where T and U only differ in specifiers. For example, if T is int and U is const T this is a conversion from a non-const integer to a const integer.
