CallSite (B2R2)

CallSite Type

Namespace: B2R2
Assembly: B2R2.Core.dll
Base Type: obj
All Interfaces: IEquatable<CallSite> , IStructuralEquatable , IComparable<CallSite> , IComparable , IStructuralComparable

Call site information of an abstract vertex in a control flow graph. Typically, there is a single concrete caller vertex that calls an abstract vertex. But in some cases, such as Continuation-Passing Style (CPS) patterns found in EVM binaries, an abstract vertex can have a chain of callers.

Union cases

Union case	Description
`ChainedCallSite(history, caller)` Full Usage: `ChainedCallSite(history, caller)` Parameters: history : `CallSite` caller : `Addr`	Chained call history from a callee to its original caller. The history always ends with a LeafCallSite, and the caller address is the address of the caller vertex, not the call site address. This is particularly useful to represent CPS patterns present in EVM binaries. history : `CallSite` caller : `Addr`
`LeafCallSite callsite` Full Usage: `LeafCallSite callsite` Parameters: callsite : `Addr`	Call site address of a concrete vertex. This serves as an end point of a call site chain. callsite : `Addr`

Instance members

Instance member	Description
`this.CallSiteAddress` Full Usage: `this.CallSiteAddress` Returns: `Addr`	Returns the address of the leaf call site. Returns: `Addr`
`this.IsChainedCallSite` Full Usage: `this.IsChainedCallSite` Returns: `bool`	Returns: `bool`
`this.IsLeafCallSite` Full Usage: `this.IsLeafCallSite` Returns: `bool`	Returns: `bool`
