-mcpu=cpu-type
Assume the defaults for the machine type cpu-type when scheduling
instructions. The choices for cpu-type are `i386', `i486', `i586', `i686',
`pentium', `pentiumpro', `k6', and `athlon'
While picking a specific cpu-type will schedule things appropriately for
that particular chip, the compiler will not generate any code that does not
run on the i386 without the `-march=cpu-type' option being used. `i586' is
equivalent to `pentium' and `i686' is equivalent to `pentiumpro'. `k6' is
the AMD chip as opposed to the Intel ones.
