Additionally, I've found classic benchmarks on
http://www.roylongbottom.org.uk including floating point focused
'whetstone'. It could be configured either for single or double precision by
just one macro definition. However its time measurement is based on
clock_gettime() method that (as far as I understand) isn't implemented for
OR1K newlib tool chain. So, the whetstone's time measurement engine have to
be ported on OR1K timer basis.
Am I right?
Or is there shorter way?

Subject: Re: [OpenRISC] FPU benchmarking
Hi,
I took a look at the other CPU benchmarks which I know and which don't
appear on the first page on Google,
but couldn't find anything suitable.
nbench:
http://www.tux.org/~mayer/linux/bmark.html
Unfortunately only one test runs with floats. And they only publish
total floating point scores
povray:
http://www.povray.org/download/benchmark.php
Probably also mainly doubles.

The FPBench of www.eembc.org (CoreMark holder) is accessible for
registered membership. (By the way the CoreMark itself is available for
free registration, but the registration doesn't grant you membership
status).
With Google II 've found:
a) Floating Point Benchmarks by John Walker
(https://www.fourmilab.ch/fbench). But is written with doubles and have to
be ported
b) FPU tests: Whetstone and Sons, Ltd.
(http://www.tux.org/~balsa/linux/benchmarking/articles/html/Article1d-3.html).
But the mentined ftp (ftp://ftp.nosc.mil/pub/aburto) is not accessible.
Does anybody knows another open sourced FPU benchmarks?
