Does Intel plan, or need to for that matter, issue an update to the C++ compiler and/or Profile Guided Optimization process for mitigation of meltdown and spectre? I see that GCC and LLVM are releasing patches. If the answer is yes, can you:
Estimate when an update would be available?
Specify if a compiler option will be available for enablement/disablement?
Estimate how much performance loss might be expected as a result of said patches?
Describe in detail the difference in code emission? For example, will you be emitting lfence operators prior to indirect branches or some other technique(s)?
Thank you for any advance notice you can provide. This will assist us in planning for release of said changes, should they be necessary.
