Packages describing “cpudetection” as local USE flag

Package“cpudetection” Flag Description
dev-libs/gmpEnables runtime CPU detection (useful for binpkgs, compatibility on other CPUs). This only works on amd64/x86 at present. If this flag is enabled, GMP will work on a variety of amd64/x86 CPUs and load accelerated routines for use at runtime depending on the CPU in use. This makes it suitable for binary packages (binpkgs). If this flag is disabled, GMP will be tuned for the CPU being used at build-time and may not be usable on other machines.
dev-python/numpyEnable dynamic dispatch to additional CPU extensions not covered by enabled CPU_FLAGS_*. This permits NumPy to benefit from improved performance when CPUs support more instruction sets, while preserving compatibility with the baseline set by CPU_FLAGS_*.
dev-python/tablesEnables runtime CPU detection (useful for bindist, compatibility on other CPUs)
media-video/ffmpeg-chromiumEnables runtime CPU detection (useful for bindist, compatibility on other CPUs)
media-video/mplayerEnables runtime CPU detection (useful for binpkgs, compatibility on other CPUs)
sci-libs/openblasBuild dynamic architecture detection at run time (for multi targets)
