static Ptr Rose::BinaryAnalysis::InstructionSemantics2::SymbolicSemantics::Merger::instance ( )
inlinestatic

Allocating constructor.

size_t Rose::BinaryAnalysis::InstructionSemantics2::SymbolicSemantics::Merger::setSizeLimit ( ) const
inline

Property: Maximum set size.

The maximum number of members in a set when merging two expressions. For instance, when merging expressions "x" and "y" with a limit of one (the default), the return value is bottom, but if the size limit is two or more, the return value is (set x y). Merging two sets (or a set and a singlton) works the same way: if the union of the two sets is larger than the size limit then bottom is returned, otherwise the union is returned.

A limit of zero has the same effect as a limit of one since a singleton set is represented by just the naked member (that is, (set x) gets simplified to just x).
