Member Function Documentation

◆ allocateInject()

int4 PcodeInjectLibrarySleigh::allocateInject	(	const string &	sourceName,
		const string &	name,
		int4	type
	)

protectedvirtual

Allocate a new InjectPayload object.

This acts as an InjectPayload factory. The formal name and type of the payload are given, this library allocates a new object that fits with its storage scheme and returns the id.

Parameters

sourceName	is a string describing the source of the new payload
name	is the formal name of the payload
type	is the formal type (CALLFIXUP_TYPE, CALLOTHERFIXUP_TYPE, etc.) of the payload

Returns: the id associated with the new InjectPayload object

Implements PcodeInjectLibrary.

◆ getBehaviors()

const vector< OpBehavior * > & PcodeInjectLibrarySleigh::getBehaviors ( void )

virtual

Get the array of op-code behaviors for initializing and emulator.

Behaviors are pulled from the underlying architecture in order to initialize the Emulate object which services the p-code script payloads.

Returns: the array of OpBehavior objects indexed by op-code

Implements PcodeInjectLibrary.

◆ getCachedContext()

virtual InjectContext& PcodeInjectLibrarySleigh::getCachedContext ( void )

inlinevirtual

Retrieve a reusable context object for this library.

The object returned by this method gets passed to the payload inject() method. The clear() method must be called between uses.

Returns: the cached context object

Implements PcodeInjectLibrary.

◆ manualCallFixup()

int4 PcodeInjectLibrarySleigh::manualCallFixup	(	const string &	name,
		const string &	snippetstring
	)

virtual

Manually add a call-fixup payload given a compilable snippet of p-code source.

The snippet is compiled immediately to produce the payload.

Parameters

name	is the formal name of the new payload
snippetstring	is the compilable snippet of p-code source

Returns: the id of the new payload

Implements PcodeInjectLibrary.

◆ manualCallOtherFixup()

int4 PcodeInjectLibrarySleigh::manualCallOtherFixup	(	const string &	name,
		const string &	outname,
		const vector< string > &	inname,
		const string &	snippet
	)

virtual

Manually add a callother-fixup payload given a compilable snippet of p-code source.

The snippet is compiled immediately to produce the payload. Symbol names for input and output parameters must be provided to the compiler.

Parameters

name	is the formal name of the new payload
outname	is the name of the output symbol
inname	is the ordered list of input symbol names
snippet	is the compilable snippet of p-code source

Returns: the id of the new payload

Implements PcodeInjectLibrary.

◆ registerInject()

void PcodeInjectLibrarySleigh::registerInject ( int4 injectid )

protectedvirtual

Finalize a payload within the library, once the payload is initialized.

This provides the derived class the opportunity to add the payload name to the symbol tables or do anything else it needs to once the InjectPayload object has been fully initialized.

Parameters

injectid is the id of the InjectPayload to finalize

Implements PcodeInjectLibrary.

◆ restoreDebug()

void PcodeInjectLibrarySleigh::restoreDebug ( const Element * el )

virtual

A method for reading in p-code generated externally for use in debugging.

Instantiate a special InjectPayloadDynamic object initialized with an <injectdebug> tag. Within the library, this replaces the original InjectPayload, allowing its p-code to be replayed for debugging purposes.

Parameters

el	is the <injectdebug> element

Reimplemented from PcodeInjectLibrary.
