* Implementation of the RA-Interface for an external, (non-SSA) register allocator.
*
* The external register allocator is a program taking 2 arguments:
- * 1) An input file in which the cfg is defined
- * 2) An output file containing the essential actions performed during allocation
+ * 1) An input file in which the interference graph is defined
+ * 2) An output file containing the instructions to perform
*

- /* TODO: Insert right code here. *
- be_set_constr_single_reg(cpy, -1, ®);

+ be_set_constr_limited(cpy, -1, &req);
}
}
}
* Read in results and apply them
