testcases accordingly. Some are currently xfailed and will be filed as bugs to be fixed or understood. Performance results: roughly neutral on SPEC some micro benchmarks in the llvm suite are up between 100 and 150%, only a pair of regressions that are due to be investigated john-the-ripper saw: 10% improvement in traditional DES 8% improvement in BSDI DES 59% improvement in FreeBSD MD5 67% improvement in OpenBSD Blowfish 14% improvement in LM DES Small compile time impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127208 91177308-0d34-0410-b5e6-96231b3b80d8
