Method Details

hasDef

public boolean hasDef()

Description copied from class: SSAInstruction

Does this instruction define a normal value, as distinct from a set of exceptions possibly thrown by it (e.g. for invoke instructions).

Overrides:

hasDef in class SSAInstruction

Returns:

true if the instruction does define a proper value.

getDef

public int getDef()

Overrides:

getDef in class SSAInstruction

getDef

public int getDef(int i)

Description copied from class: SSAInstruction

Return the ith def

Overrides:

getDef in class SSAInstruction

Parameters:

i - number of the def, starting at 0.

getNumberOfDefs

public int getNumberOfDefs()

Overrides:

getNumberOfDefs in class SSAInstruction

• SSAInstruction.getNumberOfUses()

getNumberOfUses

public int getNumberOfUses()

Overrides:

getNumberOfUses in class SSAInstruction

getUse

public int getUse(int j)

Overrides:

getUse in class SSAInstruction

Returns:

value number representing the jth use in this instruction. -1 means TOP (i.e., the value doesn't matter)

hashCode

public int hashCode()

Specified by:

hashCode in class SSAInstruction
