Hello,
using gcc-2.95.1 on an Intel machine the results of running the
Stepanov benchmark ...
ftp://ftp.kai.com/pub/benchmarks/stepanov_v1p2.C
.. are slightly pear shaped.
In short, failures with optimizations levels 0,1 and 2 but not 3
due to NaN's.
On a Sun machine, same compiler, the ration between test0 and the
others are less than zero, not quite reasonable but I need to have
a look.
Attached are the intermediate files for the Intel based compiler
and optimizations -O0 and -O3. Might be this is related to Intels'
floating point format though.
Ta',
Juergen
