Dimitry Andric cbafd2630b Add support for selectively enabling LLVM targets ... This makes it possible, through src.conf(5) settings, to select which LLVM targets you want to build during buildworld. The current list is: * (WITH|WITHOUT)_LLVM_TARGET_AARCH64 * (WITH|WITHOUT)_LLVM_TARGET_ARM * (WITH|WITHOUT)_LLVM_TARGET_MIPS * (WITH|WITHOUT)_LLVM_TARGET_POWERPC * (WITH|WITHOUT)_LLVM_TARGET_SPARC * (WITH|WITHOUT)_LLVM_TARGET_X86 To not influence anything right now, all of these are on by default, in situations where clang is enabled. Selectively turning a few targets off manually should work. Turning on only one target should work too, even if that target does not correspond to the build architecture. (In that case, LLVM_NATIVE_ARCH will not be defined, and you can only use the resulting clang executable for cross-compiling.) I performed a few measurements on one of the FreeBSD.org reference machines, building clang from scratch, with all targets enabled, and with only the x86 target enabled. The latter was ~12% faster in real time (on a 32-core box), and ~14% faster in user time. For a full buildworld the difference will probably be less pronounced, though.
