Constructor Detail

ConditionalJumpInstruction

public ConditionalJumpInstruction(org.jf.dexlib2.iface.instruction.Instruction instruction,
                                  int codeAdress)

Method Detail

ifStatement

protected abstract IfStmt ifStatement(DexBody body)

Return an if statement depending on the instruction.

jimplify

public void jimplify(DexBody body)

Description copied from class: DexlibAbstractInstruction

Jimplify this instruction.

Specified by:

jimplify in class DexlibAbstractInstruction

Parameters:

body - to jimplify into.

deferredJimplify

public void deferredJimplify(DexBody body)

Description copied from interface: DeferableInstruction

Jimplify this instruction with the guarantee that every other (non-deferred) instruction has been jimplified.

Specified by:

deferredJimplify in interface DeferableInstruction

Parameters:

body - to jimplify into

getComparisonExpr

protected ConditionExpr getComparisonExpr(DexBody body,
                                          int reg)

Get comparison expression depending on opcode against zero or null. If the register is used as an object this will create a comparison with null, not zero.

Parameters:

body - the containing DexBody

reg - the register to compare against zero.

getComparisonExpr

protected ConditionExpr getComparisonExpr(Immediate one,
                                          Immediate other)

Get comparison expression depending on opcode between two immediates

Parameters:

one - first immediate

other - second immediate

Throws:

RuntimeException - if this is not a IfTest or IfTestz instruction.
