The units[] array could be accessed out of its bounds due the lack of
verification of the max vector value.
To make this function not prone to error "P" and "E" suffixes were added.
Despite the new suffixes are unrelated to current ia64 vm magnitudes, they
make the code ready for it and avoid misleadings.
Caught using static analysis (cppcheck).
