USE flags

  • abi_mips_n32 - 64-bit (32-bit pointer) libraries
  • abi_mips_n64 - 64-bit libraries
  • abi_mips_o32 - 32-bit libraries
  • abi_ppc_32 - 32-bit (ppc) libraries
  • abi_ppc_64 - 64-bit (ppc64) libraries
  • abi_s390_32 - 32-bit (s390) libraries
  • abi_s390_64 - 64-bit (s390x) libraries
  • abi_x86_32 - 32-bit (x86) libraries
  • 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_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
  • float - Link default library to single precision instead of double (symlinks only and fftw-2.1)
  • 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"
  • quad - Build quadruple precision lib
  • sse - Use the SSE instruction set
  • sse2 - Use the SSE2 instruction set
  • static-libs - Build static versions of dynamic libraries as well
  • test - Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in make.conf/package.use anymore
  • threads - Add threads support for various packages. Usually pthreads
  • zbus - Adds support for ZBus cycle-counter of mips
