Method Details

copyForSSA

public SSAInstruction copyForSSA(SSAInstructionFactory insts,
 int[] defs,
 int[] uses)

Description copied from class: SSAInstruction

This method is meant to be used during SSA conversion for an IR that is not in SSA form. It creates a new SSAInstruction of the same type as the receiver, with a combination of the receiver's uses and defs and those from the method parameters.

In particular, if the 'defs' parameter is null, then the new instruction has the same defs as the receiver. If 'defs' is not null, it must be an array with a size equal to the number of defs that the receiver instruction has. In this case, the new instruction has defs taken from the array. The uses of the new instruction work in the same way with the 'uses' parameter.

Note that this only applies to CAst-based IR translation, since Java bytecode-based IR generation uses a different SSA construction mechanism.

TODO: move this into the SSAInstructionFactory

Specified by:

copyForSSA in class SSAInstruction

getNumberOfUses

public int getNumberOfUses()

Overrides:

getNumberOfUses in class SSAInstruction

toString

public String toString(SymbolTable symbolTable)

Overrides:

toString in class SSAAbstractInvokeInstruction

visit

public void visit(SSAInstruction.IVisitor v)

Description copied from class: SSAInstruction

Apply an IVisitor to this instruction. We invoke the appropriate IVisitor method according to the type of this instruction.

Specified by:

visit in class SSAInstruction

getNumberOfPositionalParameters

public int getNumberOfPositionalParameters()

Description copied from class: SSAAbstractInvokeInstruction

How many parameters does this call specify?

Specified by:

getNumberOfPositionalParameters in class SSAAbstractInvokeInstruction

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)

getFunction

public int getFunction()

getExceptionTypes

public Collection<TypeReference> getExceptionTypes()

Description copied from class: SSAInstruction

This method should never return null.

Overrides:

getExceptionTypes in class SSAInstruction

Returns:

the set of exception types that an instruction might throw ... disregarding athrows and invokes.

hashCode

public int hashCode()

Specified by:

hashCode in class SSAInstruction
