Member Function Documentation

◆ initialize()

virtual void SleighCompile::initialize ( DocumentStorage store)
inlinevirtual

Initialize the translator given XML configuration documents.

A translator gets initialized once, possibly using XML documents to configure it.

Parameters
storeis a set of configuration documents

Implements Translate.

◆ instructionLength()

virtual int4 SleighCompile::instructionLength ( const Address baseaddr) const
inlinevirtual

Get the length of a machine instruction.

This method decodes an instruction at a specific address just enough to find the number of bytes it uses within the instruction stream.

Parameters
baseaddris the Address of the instruction
Returns
the number of bytes in the instruction

Implements Translate.

◆ oneInstruction()

virtual int4 SleighCompile::oneInstruction ( PcodeEmit emit,
const Address baseaddr 
) const
inlinevirtual

Transform a single machine instruction into pcode.

This is the main interface to the pcode translation engine. The dump method in the emit object is invoked exactly once for each pcode operation in the translation for the machine instruction at the given address. This routine can throw either

Parameters
emitis the tailored pcode emitting object
baseaddris the Address of the machine instruction
Returns
the number of bytes in the machine instruction

Implements Translate.

◆ printAssembly()

virtual int4 SleighCompile::printAssembly ( AssemblyEmit emit,
const Address baseaddr 
) const
inlinevirtual

Disassemble a single machine instruction.

This is the main interface to the disassembler for the processor. It disassembles a single instruction and returns the result to the application via the dump method in the emit object.

Parameters
emitis the disassembly emitting object
baseaddris the address of the machine instruction to disassemble

Implements Translate.
