ABSTRACT:
A method of converting an original code sequence to a modified code sequence where the original code sequence includes a procedure call that is prior to a load instruction that is configured to load a value into one of a first plurality of registers is provided. The method includes inserting an advanced load instruction associated with one of a second plurality of registers into the modified code sequence where the advanced load instruction is configured to cause the value to be loaded into the one of the first plurality of registers. The method also includes inserting the procedure call into the modified code sequence subsequent to the advanced load instruction and inserting a checking instruction associated with the one of the second plurality of registers into the modified code sequence subsequent to the procedure call.
