About processor optimisation with gcc



Hi all

I am just compiling a math library, ccmath. I would like to know how can

I compile for a specific processor. cc/gcc does not recognise anything
beyond 486 and I am running a PIII(just confirmed...)

I wonder how kernel gets compiled for specific processor though. I lists

PII/PII/AMD/586/686 etc....

Any suggestions?

Bye
