Subject: core2 flag for arch on gcc 4.3.2

Hello everyone,

   I am planning to migrate my linux to 4.3.2 but, current flag for core 2 duo is nocona.
I couldn't find elaborate explanation of core2 flag compare to nocona.
What is difference between core2 and nocona flags?
Do they behave identical or core2 offers better performance/tunning?

Thanks,
Tom
