Detailed Description

An operation that reads from volatile memory.

This CALLOTHER p-code operation takes as its input parameter, after the constant id, a reference Varnode to the memory being read. The output returned by this operation is the actual value read from memory.

Member Function Documentation

getOperatorName()

string VolatileReadOp::getOperatorName ( const PcodeOp *  op ) const

virtual

Get the symbol representing this operation in decompiled code.

This will return the symbol formally displayed in source code, which can be tailored more than the low-level name

Parameters

op	is the operation (in context) where a symbol is needed

Returns

the symbol as a string

Reimplemented from UserPcodeOp.

References VolatileOp::appendSize(), PcodeOp::getOut(), Varnode::getSize(), and UserPcodeOp::name.

restoreXml()

void VolatileReadOp::restoreXml ( const Element *  el )

virtual

Restore the detailed description from an XML stream.

The details of how a user defined operation behaves can be dynamically configured from an XML tag.

Parameters

el	is the root XML element describing the op

Implements UserPcodeOp.
