ghidra.pcode.emu.jit.analysis.JitControlFlowModel.BlockFlow

Record Components:

from - the block from which execution flows. In the case of a non-fall-through branch, the block should end with the branching p-code op. For conditional fall-through, it should end with the PcodeOp.CBRANCH op. For unconditional fall-through, it could end with any op having fall through.

to - the block to which execution flows. The block must start with the target op of the branch.

branch - the branch effecting the flow of execution

Enclosing class:

JitControlFlowModel

public static record JitControlFlowModel.BlockFlow(JitControlFlowModel.JitBlock from, JitControlFlowModel.JitBlock to, JitPassage.IntBranch branch)
extends Record

A flow from one block to another

This is just a wrapper around an JitPassage.IntBranch that allows us to quickly identify what two blocks it connects. Note that to connect two blocks in the passage, the branch must by definition be an JitPassage.IntBranch.

If this flow represents entry into the passage, then from() and branch() may be null

Constructor Details

BlockFlow

public BlockFlow(JitControlFlowModel.JitBlock from,
 JitControlFlowModel.JitBlock to,
 JitPassage.IntBranch branch)

Creates an instance of a BlockFlow record class.

Parameters:

from - the value for the from record component

to - the value for the to record component

branch - the value for the branch record component

Method Details

entry

public static JitControlFlowModel.BlockFlow entry(JitControlFlowModel.JitBlock to)

Create an entry flow to the given block

Parameters:

to - the block to which execution flows

Returns:

the flow

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

from

public JitControlFlowModel.JitBlock from()

Returns the value of the from record component.

Returns:

the value of the from record component

to

public JitControlFlowModel.JitBlock to()

Returns the value of the to record component.

Returns:

the value of the to record component

branch

public JitPassage.IntBranch branch()

Returns the value of the branch record component.

Returns:

the value of the branch record component
