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- Overrides:

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.- Overrides:

- See Also:
SSAInstruction.visit(IVisitor)
-
isFallThrough
public boolean isFallThrough()
- Overrides:
isFallThrough
in classSSAPutInstruction
- Returns:
- true iff this instruction may fall through to the next
-
getExceptionTypes
public Collection<TypeReference> getExceptionTypes()
Description copied from class:SSAInstruction
This method should never return null.- Overrides:
