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: this is kind of arcane? Move this out into CAst?

Overrides:

copyForSSA in class SSAPutInstruction

getExceptionTypes

public java.util.Collection<TypeReference> getExceptionTypes()

Description copied from class: SSAInstruction

This method should never return null.

Overrides:

getExceptionTypes in class SSAFieldAccessInstruction

Returns:

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