Subject: Ada speed vs. C...

In response to recent requests for comparisons of the speed of
the code generated by Ada compilers vs. C compilers, the following
results were originally described at the Tri-Ada '88 conference
in Charleston, WV on October 26, 1988:
--------------------------------------------------------------------------
Among the C compilers chosen were those that produced the best times on
16.77 Mhz 68020 based machines out of a list of published dhrystone results
for 300 compilers. The TeleSoft TeleGen2 optimizing compiler was compared
against four other C compilers:
Sun/Unix 3.2 C on a Sun 3/160
GreenHills C on ISI optimum V machine
Gnu C on a Sun 3/160
MASSCOMP C on RTU 3.1, NC-5700 machine
MASSCOMP had the best C compiler, our Ada compiler only beat it by a very
small margin.
The whole point of the comparison was not to prove that Ada is better than
C but that it's possible for Ada compilers to generate code that is just
as good or better than C compilers. It takes a lot of time and effort to
go from a compiler that meets the minimum language requirements to a
highly optimizing compiler. Ada compilers will continue to improve and
you can expect to see more optimizing compilers from a variety of sources.
