Binary inliner.
This binary inliner builds a new CFG (called here the paths graph) from a master CFG. The paths graph initially contains some vertices that correspond to a function call site in the master CFG, and this inliner will copy part of the master CFG corresponding to the called function into the paths graph.
When a function is copied from the master CFG to the paths graph, only those edges in the called function that participate in some path from the entry vertex to a returning vertex are copied. Usually a call site will call a single function, but an indirect call (e.g., x86 call eax) could have calls to multiple functions, and/or the special indeterminate vertex (e.g., depending on whether anything is known about eax in call eax). Once all the functions called from a call site are inlined, the E_CALL_RETURN edge is removed from that vertex.
The inliner has an optional list of blacklisted vertices and edges. These vertices and edges cannot appear in any path.
A user-defined predicate determines whether a function call should be inlined or skipped.

Construct a CFG with inlined functions.
Computes paths in the partitioner's global CFG from cfgBeginVertices to cfgEndVertices that do not pass through cfgAvoidVertices or cfgAvoidEdges. Any function calls along these paths are then inlined, but only those paths through the function that don't pass through the cfgAvoidVertices or cfgAvoidEdges. The return value of the shouldInline property callback determines whether a function is inlined or summarized.
Returns the resulting control flow graph, a.k.a., the paths graph.

Paths begin vertices.
This is the set of vertices corresponding to the cfgBeginVertices of the inlinePaths function. Only those CFG vertices that are part of a path are in this set.

Paths end vertices.
This is the set of vertices corresponding to the cfgEndVertices of the inlinePaths function. Only those CFG vertices that are part of a path are in this set.
