There is more code committed. Check-out or wait for *tomorrow*
openssl-SNAP-20120919 snapshot. There is SmartMIPS AES code (pass
-msmartmips to Configure) and Configure accepts double dash as compiler
options. Please double-check and optionally post performance for new AES
code.
I've done some speed tests incase anyone is interested. linux-generic32,
then with 2 levels of asm optimizations, mips32r2 and finally smartmips.
Nice performance boost for smartmips AES.
