Member Function Documentation

inject()

void InjectPayloadSleigh::inject ( InjectContext &  context, PcodeEmit &  emit  ) const

virtual

Perform the injection of this payload into data-flow.

P-code operations representing this payload are copied into the controlling analysis context. The provided PcodeEmit object dictates exactly where the PcodeOp and Varnode objects are inserted and to what container. An InjectContext object specifies how placeholder elements become concrete Varnodes in the appropriate context.

Parameters

context	is the provided InjectConject object
emit	is the provovided PcodeEmit object

Implements InjectPayload.

restoreXml()

void InjectPayloadSleigh::restoreXml ( const Element *  el )

virtual

Restore this payload from an XML stream.

The base class version of this method restores from a <pcode> tag. Derived classes may restore from a parent tag and then invoke the base class method.

Parameters

el	is the XML element

Reimplemented from InjectPayload.

Reimplemented in InjectPayloadCallother, and InjectPayloadCallfixup.
