This is just those case when Ada compiler support for IA32+ SIMD
extensions could drastically improve efficiency ( not only in percents
but in times).
This topic was discussed recently but it seems that it is not among
priority issues among Ada compiler implementators ;-(
Actually it is not too bad as one could implement that using assembler
which has all SIMD operations available for the particular chip.
Then that routines could be easily imported into Ada library package
that provides interface to them.
