Detailed Description

Root class for all decompiler specific commands.

Commands share the data object IfaceDecompData and are capable of iterating over all functions in the program/architecture.

Member Function Documentation

createData()

virtual IfaceData * IfaceDecompCommand::createData ( void  )

inlinevirtual

Create a specialized data object for this command (and its module)

This method is only called once per module

Returns

the newly created data object for the module

Implements IfaceCommand.

getModule()

virtual string IfaceDecompCommand::getModule ( void  ) const

inlinevirtual

Get the formal module name to which this command belongs.

Commands in the same module share data through their registered IfaceData object

Returns

the formal module name

Implements IfaceCommand.

iterateFunctionsAddrOrder() [1/2]

void IfaceDecompCommand::iterateFunctionsAddrOrder ( Scope *  scope )

protected

Iterate over all functions in a given scope.

Runs over every function in the scope calling iterationCallback().

Parameters

scope

is the given scope

References Scope::begin(), Scope::end(), FunctionSymbol::getFunction(), and iterationCallback().

iterateFunctionsAddrOrder() [2/2]

void IfaceDecompCommand::iterateFunctionsAddrOrder

(

void

)

Iterate command over all functions in all scopes.

Scopes are traversed depth-first, then within a scope, functions are traversed in address order.

References IfaceDecompData::conf, dcp, Database::getGlobalScope(), iterateScopesRecursive(), and Architecture::symboltab.

Referenced by IfcProduceC::execute(), IfcPrintInputsAll::execute(), IfcDuplicateHash::execute(), IfcCallGraphBuild::execute(), IfcCallGraphBuildQuick::execute(), and iterateScopesRecursive().

iterateFunctionsLeafOrder()

void IfaceDecompCommand::iterateFunctionsLeafOrder

(

void

)

Iterate command over all functions in a call-graph traversal.

Traversal is based on the current CallGraph for the program. Child functions are traversed before their parents.

References IfaceDecompData::cgraph, IfaceDecompData::conf, dcp, and iterationCallback().

Referenced by IfcProducePrototypes::execute(), and IfcCallGraphList::execute().

iterateScopesRecursive()

void IfaceDecompCommand::iterateScopesRecursive ( Scope *  scope )

protected

Iterate recursively over all functions in given scope.

Runs over every function in the scope, or any sub-scope , calling iterationCallback()

Parameters

scope

is the given scope

References Scope::childrenBegin(), Scope::childrenEnd(), Scope::isGlobal(), iterateFunctionsAddrOrder(), and iterateScopesRecursive().

Referenced by iterateFunctionsAddrOrder(), and iterateScopesRecursive().

iterationCallback()

virtual void IfaceDecompCommand::iterationCallback ( Funcdata *  fd )

inlinevirtual

Perform the per-function aspect of this command.

Parameters

fd	is the particular function to operate on

Reimplemented in IfcProduceC, IfcProducePrototypes, IfcPrintInputsAll, IfcDuplicateHash, IfcCallGraphBuild, and IfcCallGraphList.

Referenced by iterateFunctionsAddrOrder(), and iterateFunctionsLeafOrder().

setData()

virtual void IfaceDecompCommand::setData ( IfaceStatus *  root, IfaceData *  data  )

inlinevirtual

Associate a specific data object with this command.

Parameters

root	is the interface object this command is registered with
data	is the data object the command should use

Implements IfaceCommand.
