Description

Callback to limit basic block size.

This basic block callback limits the number of instructions in a basic block. During basic block discovery when instructions are repeatedly appended to a block, if the number of instructions reaches the limit then the block is forced to terminate. This is useful when instruction semantics are enabled since large basic blocks can slow down the semantic analysis.

◆ instance()

static Ptr Rose::BinaryAnalysis::Partitioner2::Modules::BasicBlockSizeLimiter::instance ( size_t maxInsns )

Constructor.

Definition at line 217 of file Modules.h.

◆ maxInstructions() [1/2]

size_t Rose::BinaryAnalysis::Partitioner2::Modules::BasicBlockSizeLimiter::maxInstructions ( ) const

inline

Property: Maximum size of block.

A value of zero means no maximum, effectively disabling this callback without removing it from the callback list.

◆ maxInstructions() [2/2]

void Rose::BinaryAnalysis::Partitioner2::Modules::BasicBlockSizeLimiter::maxInstructions ( size_t maxInsns )

inline

Property: Maximum size of block.

A value of zero means no maximum, effectively disabling this callback without removing it from the callback list.

◆ operator()()

virtual bool Rose::BinaryAnalysis::Partitioner2::Modules::BasicBlockSizeLimiter::operator()	(	bool	chain,
		const Args &
	)

overridevirtual

Callback method.

This is the method invoked for the callback. The chain argument is the return value from the previous callback in the list (true for the first callback). The successor callbacks use chain to indicate whether subsequent callbacks should do anything.

Implements Rose::BinaryAnalysis::Partitioner2::BasicBlockCallback.
