[fpc-pascal] Best optimizations for Intel Quad Core CPU

[Graeme Geldenhuys]

Hi,

I know when deploying an application, it is always best to be
conservative with the compiler optimization options - thus your
application can run on most CPU's out there (maximum compatibility).

But what is the best optimization options I can specify for my own
system. This includes FPC itself, Lazarus IDE, MSEide, fpGUI DocView,
fpGUI UI Designer etc... all the tools I use on a daily basis.

I find it a waist compiling for 386 CPU compatibility, when there is not
a single person in our office still running a 386 system.

So for a start, I want to optimize the application that run on MY
system. This is the CPU I have in my system:
