Hi,
I've seen that in the new llvm version (7.0) there are some mitigations for Spectre v1, so the clang compiler might have them implemented, but, by the way, any of the command line flag works. I've downloaded the llvm source code and have seen that there are 3 dependencies broken on lib/Target/X86/X86SpeculativeLoadHardening.cpp -> lib/Target/X86/MCTargetDesc/ should have X86GenRegisterInfo.inc, X86GenInstrInfo.inc and X86GenSubtargetInfo.inc files, but it doesn't. It's this causing the problem?
There's some way to apply the mitigation or it haven't been done yet?
Cheers,
Andrés
