Detailed Description

Abstract class for emitting pcode to an application.

Translation engines pass back the generated pcode for an instruction to the application using this class.

Member Function Documentation

decodeOp()

void ghidra::PcodeEmit::decodeOp	(	const Address &	addr,
		Decoder &	decoder
	)

Emit pcode directly from an <op> element.

A convenience method for passing around p-code operations via stream. A single p-code operation is parsed from an <op> element and returned to the application via the PcodeEmit::dump method.

Parameters

addr	is the address (of the instruction) to associate with the p-code op
decoder	is the stream decoder

dump()

virtual void ghidra::PcodeEmit::dump ( const Address &  addr, OpCode  opc, VarnodeData *  outvar, VarnodeData *  vars, int4  isize  )

pure virtual

The main pcode emit method.

A single pcode instruction is returned to the application via this method. Particular applications override it to tailor how the operations are used.

Parameters

addr	is the Address of the machine instruction
opc	is the opcode of the particular pcode instruction
outvar	if not null is a pointer to data about the output varnode
vars	is a pointer to an array of VarnodeData for each input varnode
isize	is the number of input varnodes

Implemented in ghidra::PcodeEmitCache, ghidra::DisassemblyEngine, ghidra::PcodeRawOut, and ghidra::PcodeEmitFd.

Referenced by decodeOp(), and ghidra::PcodeCacher::emit().
