I wonder if this was part of the Android SDK earlier? I remember seeing some header/C file called cpu-feature in there at some point.

I fail to see what the difference between this and several existing packages (most of them named "cpuid" or "libcpuid") is, aside of lacking x86 support for /proc/cpuinfo.

There is none, there are hundreds of these on github already. What could be actually useful is if google tried to push single version of this as compiler builtins for gcc, clang and msvc. GCC already has__builtin_cpu_supports("mmx"), but it's still pretty useless since other compilers don't implement it or implement it differently.

What makes you think it's Windows-only?
