[PATCH] D76158: Add inline assembly load hardening mitigation for Load Value Injection (LVI) on X86 [6/6]

[Scott Constable via Phabricator via llvm-commits]

Herald added a project: LLVM.

Addressed comments from @craig.topper.

The coverage of the LVI mitigations for LLVM should match the coverage of the mitigations implemented for binutils. Both should adhere to the guidance outlined in this document: https://software.intel.com/security-software-guidance/insights/deep-dive-load-value-injection.

Mitigations have only been recommended for SGX enclave code. Since SGX enclaves do not support far procedure calls and branches (and therefore far returns), these features do not need to be covered by either mitigation tool.
