instal the new version for apple Spectre

This post is intended as a follow-up to Terry Myerson’s recent Windows System post with a focus on the assessment for MSVC. On the MSVC team, we’ve reviewed information in detail and conducted extensive tests, which showed the performance impact of the new /Qspectre switch to be negligible. Microsoft is aware of a new publicly disclosed class of vulnerabilities, called “speculative execution side-channel attacks,” that affect many operating systems and modern processors, including processors from Intel, AMD, and ARM. Second, we have provided Spectre-mitigated implementations of the Microsoft Visual C++ libraries. First, the /Qspectre switch is now supported regardless of the selected optimization level. Update 4 April 2018 With Visual Studio 2017 version 15.7 Preview 3 we have two new features to announce with regards to our Spectre mitigations. Update 20 April 2018 With Visual Studio 2017 version 15.7 Preview 4 we have added a new warning, C5045, that shows what patterns in your code would have caused a mitigation to be inserted.
