Google Engineer Shows "SESES" For Mitigating LVI + Side-Channel Attacks - Code Runs ~7% Original Speed

Disclosed last week was the Load Value Injection attack affecting Intel CPUs and requiring new mitigations. While the GNU Assembler mitigation options were quickly added, on the LLVM toolchain side the developers there continue evaluating the proposed LVI mitigation along with another option that looks to mitigate more than just LVI. The "SESES" proposal looks more broadly at mitigating CPU side-channel vulnerabilities but with shattering performance hits...
