I see, thanks. In other words, as it turns out my suggestion about run-time switch does not apply in this case, because minimum of SSE2 is actually *assumed* for x86_64 platform. And this doesn't hold true for Knights Corner. But it does hold true for Knights Landing, doesn't it? I see no point in attempting to accommodate assembler support for Knights Corner (too rare processor) and would appreciate if you could confirm if following works with 1.0.2: ./Configure linux-x86_64-icc no-asm -mmic BTW, _lrotl fix is applied to 1.0.1, but not earlier versions, which are open for security fixes only. _______________________________________________ openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev
