In my code I have a bunch of routines optimized for different platforms, e.g. using x86 AESNI instructions. Not all compilers support them, and they don't even make sense when compiling for a different CPU architecture. It's much simpler to say "enable this if we can compile it" rather than detecting the compiler and target platform and throwing a mess of conditional compilation into an autoconf script. |
