Without -O the GNU compilers do not optimize at all. The generated
code is quite bad.

If removing -O options brings the performance down to Delphi, and a mere -O1
can beat Delphi, that suggests that Delphi doesn't optimize, at least with
regard to the program being tested.

Or something else is wrong, which makes the programs not comparable.
(That's always a problem when comparing programs written in different
languages. They really have to have a very similar data and code organization
for that to be valid as a compiler comparison.)

Anyway, nobody in their right mind who is past the end of their puberty, or
past the year 1992, whichever came first, uses Delphi.

The last programmer I met who swore by Delphi was a 19 year old co-op student
back in 1999, doing QA work.  He said brilliant things like "Unicode is
gay with all these space-wasting wide characters; everyone should just learn
English and use ASCII".

Was that you?
