samkellett added a comment to D41723: Introduce the "retpoline" x86 mitigation technique for variant #2 of the speculative execution vulnerabilities disclosed today, specifically identified by CVE-2017-5715, "Branch Target Injection", and is one of the two halves to Spectre...

@chandlerc is MacOS support omitted intentionally (ie. not implemented yet)? When I try using the -mretpoline flag on High Sierra I get the following:

fatal error: error in backend: MachO doesn't support COMDATs, '__llvm_retpoline_r11' cannot be lowered.
