Please also add a new target to multiversioning and corresponding testcases. As an example, how this is done nowadays, please see a submission for a different target at [1]. BTW: It looks that multiversioning testcases lack AMD targets. Can you please add a testcase similar to testsuite/g++.target/i386/mv16.C and also add AMD targets to testsuite/gcc.target/i386/funcspec-56.inc. (this can be done in a follow-up patch).
