Detailed Description

Abstract class performing an override of p-code on an instruction.

Instances operate directly on raw p-code emitted for a single instruction, prior to incorporation in the syntax tree.

encode()

virtual void ghidra::Override::Record::encode ( Encoder &  encoder, const Address &  addr  ) const

pure virtual

Encode this record to stream.

Parameters

encoder	is the stream
addr	is the address of the instruction the override applies to

performOverride()

virtual void ghidra::Override::Record::performOverride ( const Address &  addr, Funcdata &  data  ) const

pure virtual

Perform p-code modifications for the instruction at the given address.

Parameters

addr	is the given address of the instruction
data	is the function

Implemented in ghidra::Override::Branch, ghidra::Override::Call, ghidra::Override::CallReturn, ghidra::Override::Return, ghidra::Override::CallotherCall, ghidra::Override::CallotherBranch, and ghidra::Override::CallCall.

printRaw()

virtual void ghidra::Override::Record::printRaw ( ostream &  s, const Address &  addr  ) const

pure virtual

Print a description of the override as a console message.

Parameters

s	is the stream to write to
addr	is the address this override applies to
