asmjit::JumpNode Class Reference

Inheritance diagram for asmjit::JumpNode:

Jump instruction with JumpAnnotation.

Note

This node should be only used to represent jump where the jump target cannot be deduced by examining instruction operands. For example if the jump target is register or memory location. This pattern is often used to perform indirect jumps that use jump table, e.g. to implement switch{} statement.
