New Targets and Target Specific Improvements
* -mtune=generic can now be used to generate code running well on common x86 chips. This includes AMD Athlon, AMD Opteron, Intel Pentium-M, Intel Pentium 4 and Intel Core 2.
* -mtune=native and -march=native will produce code optimized for the host architecture as detected using the cpuid instruction.
So, if Sabayon set '-march=native' in CFlAGS after the installation it may speed up newly installed packages or even the whole system if the user chooses to do an 'emerge -e world' after installation.
It would ultimately meet the request of this thread:
Is there any problems with that that I may have overlooked?
