[Radiance-general] Re: compile options, fast-math on gcc

[Axel Jacobs]

The newer versions of GCC actually do a pretty decent job with just
the -O3 optimisation:

While I have to honestly admit that I don't know the 'perfect' compile
switches for my CPU (I borrowed them from Mark's benchmark page, from
what appeared to be a processor similar to mine), the benchmark shows
that setting too many exotic compiler options might actually decrease
the speed a little.
