If someone knowledgable enough in > that area wants to fix it, though... My suggestion would be to have a get_checksum1_sse2() and get_checksum1_sse3() and always build them. The compiler should support it. Then on runtime you would check for sse3 and based on the result get_checksum1() would either invoke the _sse2() or sse3(). Without auto detection it won't be utilized by distros. But yes, this could be improved afterwards. Sebastian

What do you base this on? Per https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html : "For the x86-32 compiler, you must use -march=cpu-type, -msse or -msse2 switches to enable SSE extensions and make this option effective. For the x86-64 compiler, these extensions are enabled by default." That reads to me like we're fine for SSE2. As stated in my comments, SSSE3 support must be
