sconstab added a comment.
There is now a more complete set of documentation for instructions that must be manually mitigated:
https://software.intel.com/security-software-guidance/insights/deep-dive-load-value-injection#specialinstructions
- The asm parser now emits a warning containing the above link whenever it encounters an instruction that cannot be automatically mitigated.
- Now emitting a warning if a REP/REPNE prefix is encountered without an accompanying instruction on the same line.
