  • abi_x86_64 - 64-bit (amd64) libraries
  • abi_x86_x32 - x32 ABI libraries
  • altivec - Add support for optimizations for G4 and G5/ppc970 processors
  • cpu_flags_arm_neon - Use the NEON (ASIMD) instruction set
  • cpu_flags_ppc_altivec - Use the AltiVec/VMX instruction set
  • cpu_flags_x86_avx - Adds support for Advanced Vector Extensions instructions
  • cpu_flags_x86_avx2 - Adds support for Advanced Vector Extensions 2 instructions
  • cpu_flags_x86_fma3 - Use the Fused Multiply Add 3 instruction set ([fma] in cpuinfo)
  • cpu_flags_x86_fma4 - Use the Fused Multiply Add 4 instruction set
  • cpu_flags_x86_sse - Use the SSE instruction set
  • cpu_flags_x86_sse2 - Use the SSE2 instruction set
  • doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
  • fortran - Add support for fortran
  • mpi - Add MPI (Message Passing Interface) layer to the apps that support it
  • neon - Enable optimization support for ARM NEON processors
  • openmp - Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
  • sse - Use the SSE instruction set
  • sse2 - Use the SSE2 instruction set
  • static-libs - Build static versions of dynamic libraries as well
  • test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
  • threads - Add threads support for various packages. Usually pthreads
  • zbus - Adds support for ZBus cycle-counter of mips
