SyscallPcodeUseropDefinition

public SyscallPcodeUseropDefinition(EmuSyscallLibrary<T> syslib)

Method Details

getName

public String getName()

Description copied from interface: PcodeUseropLibrary.PcodeUseropDefinition

Get the name of the userop.

This is the symbol assigned to the userop when compiling new Sleigh code. It cannot conflict with existing userops (except those declared, but not defined, by the executor's language) or other symbols of the executor's language. If this userop is to be used generically across many languages, choose an unlikely name. Conventionally, these start with two underscores __.

Specified by:

getName in interface PcodeUseropLibrary.PcodeUseropDefinition<T>

Returns:

the name of the userop

getInputCount

public int getInputCount()

Description copied from interface: PcodeUseropLibrary.PcodeUseropDefinition

Get the number of input operands acccepted by the userop.

Specified by:

getInputCount in interface PcodeUseropLibrary.PcodeUseropDefinition<T>

Returns:

the count or -1 if the userop is variadic

execute

public void execute(PcodeExecutor<T> executor,
 PcodeUseropLibrary<T> library,
 Varnode outVar,
 List<Varnode> inVars)

Description copied from interface: PcodeUseropLibrary.PcodeUseropDefinition

Invoke/execute the userop.

Specified by:

execute in interface PcodeUseropLibrary.PcodeUseropDefinition<T>

Parameters:

executor - the executor invoking this userop.

library - the complete library for this execution. Note the library may have been composed from more than the one defining this userop.

outVar - if invoked as an rval, the destination varnode for the userop's output. Otherwise, null.

inVars - the input varnodes as ordered in the source.
