Member Function Documentation

get_orig_cfg()

std::shared_ptr< ControlFlowGraph > ControlFlowGraphTransform::get_orig_cfg ( )

inherited

Get a shared pointer to the original ControlFlowGraph.

Returns

the original ControlFlowGraph

transform_basic_block()

std::shared_ptr< InstructionSequence > PeepholeLowLevel::transform_basic_block ( std::shared_ptr< InstructionSequence >  orig_bb )

virtual

Create a transformed version of the instructions in a basic block.

Note that an InstructionSequence "owns" the Instruction objects it contains, and is responsible for deleting them. Therefore, be careful to avoid having two InstructionSequences contain pointers to the same Instruction. If you need to make an exact copy of an Instruction object, you can do so using the duplicate() member function, as follows:

Instruction *orig_ins = // ...an Instruction object...
Instruction *dup_ins = orig_ins->duplicate();

Parameters

orig_bb

the original basic block

Returns

shared pointer to the new basic block InstructionSequence

Implements ControlFlowGraphTransform.

transform_cfg()

std::shared_ptr< ControlFlowGraph > ControlFlowGraphTransform::transform_cfg ( )

virtualinherited

Transform the original ControlFlowGraph.

Returns

shared pointer to the transformed ControlFlowGraph
