The security update of Microsoft this week included provides support to control usage of Indirect Branch Prediction Barrier (IBPB) within some AMD processors (CPUs) for mitigating CVE-2017-5715. Apart from that it also provides Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities. However I was wondering the mitigation plan coverage provided by AMD?

A insidiousness of the SIMD instruction extensions of ARM, MIPS, and x86? Does AMD cover this part because SIMD Instructions considered harmful?Any advice or we just ignore it?
