hello everyone
I'm a litle new to gcc and I would like to know how to generate binaries
that are optimized for pentium processors (that make use of pentium
instructions)
I have used some options like -mcpu=i586 -march=i586
but the resulting binaries still run on a 486... what makes me think that they
are not using pentium instructions, but as I know nothing about assembly
and about what the pentium-only instructions do, maybe the programs that I have
tested just were too simple to make use of such instructions... maybe not...
I will really appreciate some help about this =]
