Gentoo is one of the first Linux distributions to release a packaged installation for the Linux x32 architecture.
Linux x32 is the effort for a native 32-bit ABI for Intel/AMD x86_64 systems but where 32-bit pointers are used to reduce the memory footprint while still allowing for x32 programs to take advantage of the rest of the 64-bit benefits. There's x32 support within the Linux kernel, GCC, glibc, binutils, and even LLVM/Clang.
