Hi all, After hitting my head against the wall why the numbers egg's division was so much slower than Gauche while it is now using the same algorithm, I noticed that some_pointer[x/2] was much slower than some_pointer[x>>1], so the C compiler wasn't optimising this particular operation away, which is pretty unusual I thought.
This led me to find out that CHICKEN was invoking gcc with -Os, but not any other optimization options. The Makefiles add -O3 when OPTIMIZE_FOR_SPEED is defined, but -Os otherwise. The README doesn't even mention this important detail. Am I going completely mad and am I missing something obvious? Is there a good reason why optimizing for speed isn't the default? It makes sense that DEBUGBUILDs aren't optimized, but usually (anywhere except for embedded uses), I'd expect performance to be more important than binary size.
