What should be the default compiler options for the shootout benchmarks?
The used compiler is fpc 2.2.0. The benchmarks are run on a Intel
Q6600 quad-core, either with 32 bits or 64 bits Ubuntu.
There is some controversion about it, see
https://alioth.debian.org/tracker/index.php?func=detail&aid=311109&group_id=30402&atid=411002
There are two proposals:
-O3oregvar -XX -Xs
and
-XXs -Oppentiumm -Cppentiumm -O3
On 32 bit systems
-XXs -Oppentiumm -Cppentiumm -O3
On 64 bit systems
-XXs -O3
If I look at
http://svn.freepascal.org/cgi-bin/viewvc.cgi/tags/release_2_2_0/compiler/x86_64/cpuinfo.pas?view=markup
it seems that in fpc 2.2.0 regvars are not enabled. Why not?
Why does it work for Peter Blackman in the mandelbrot benchmark?
