Re: Ada Compilers

["Marin David Condic" <dont.bother.mcondic.auntie.spam@[acm.org>]

True, but misleading. GNAT and GNU C/C++ may all share the same back end &
hence produce similar code for similar input programs, but that in no way
says anything about how good the code is compared to some other compiler
that works for either Ada, C or C++. Its theoretically possible that the gcc
backend might generate really crappy code and hence Ada and C++ are equally
bad. What does that tell you about the relative efficiency of Ada or C++?

This is why its totally useless to ask the question "How does Ada compare
against C++ for efficiency...?" The best we can answer is that the Ada
standard doesn't impose anything that is inherently inefficient for the
semantic content delivered and the rest is a matter of comparing one
compiler against another. There are efficient implementations of both Ada
and C++. There are also bad implementations of both languages. We *really*
need to educate developers (who *should* know this by the time they leave
college!) that languages aren't "slow" - only implementations are.
