I've been wondering how and when OpenSSL decides whether it can use
the new aes instructions? Does it decide at build time or at run time?
If I build on a CPU that supports aes instructions but run on a cpu
that does not, will bad things happen? Or is OpenSSL smart enough to
call functions implemented without aes instructions in that case?
Runtime. See the file crypto/x86cpuid.pl which gets
converted to compiler-specific assembler source code.
Enjoy
