copyForSSA(SSAInstructionFactory insts,
int[] defs,
int[] uses)
This method is meant to be used during SSA conversion for an IR that is not in SSA form.

Return the ith def

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

toString(SymbolTable symbolTable) |

visit(SSAInstruction.IVisitor v)
Apply an IVisitor to this instruction.

public SSAInstruction copyForSSA(SSAInstructionFactory insts, int[] defs, int[] uses) throws java.lang.IllegalArgumentException
SSAInstructionIn 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.
