Subject: [Q] -m486 compile option, -O6
Date: 31 May 1993 09:32:49 GMT

What kind of optimization is provided by -m486 ?
I notice larger code and no difference in speed for my 486/66Mhz.
This is true both for gcc 2.3.3. and 2.4.0.
Is it possible that for overdrive processors code size is more
important for speed, so that using -m486 is not a good for them ?

What means -O6 ? It is never documented, and the produced code is the
same as with -O2 .
