A user defined p-code op for assisting the recovery of jump tables.
An instance of this class refers to p-code script(s) that describe how to parse the jump table from the load image. Possible scripts include:
This class stores injection ids. The scripts themselves are managed by PcodeInjectLibrary.
ghidra::JumpAssistOp::JumpAssistOp | ( | Architecture * | g | ) |
