If Mitigations Weren't Already Bad Enough: Slow Build Times Now Lead To An Unoptimized Intel LVI Pass

Disclosed back in March was the LVI attack (Load Value Injection) affecting Intel CPUs. Mitigating LVI requires compiler toolchain changes and LLVM 11 merged its LVI mitigation last month that adds a load fence after each instruction that may be vulnerable to this attack, similar to the GNU Assembler changes. Now though LLVM is adding an unoptimized version of their LVI pass...
