This page lists processor instruction sets that can be enabled on Funtoo Linux systems using the CPU_FLAGS_* variables.
CPU_FLAGS_X86
This section lists CPU flags, also known as instruction sets, supported by Gentoo and Funtoo Linux. One notable omission in this list is the x86-64 instruction set, which was developed by AMD and launched in 2003 with the first Opteron processor. All Funtoo Linux x86-64bit builds use this instruction set as a foundation. They may also use additional instructions as determined by CFLAGS and CPU_FLAGS_X86 settings that are defined in the subarch profile.
Note
Highlighted rows indicate instruction sets that were not fully adopted by the other vendor, such as AMD instruction sets not adopted by Intel.
