Intel deprecates SGX on Core series processors
I pity that MPX is gone as well, this makes x86/x64 lose to ARM in hardware memory tagging.
While it was buggy, Intel doesn't seem keen in bringing in a replacement.

MPX sure, that doesn't prevent bringing a new one, otherwise in a couple of years Intel/AMD will be the only ones left standing without hardware memory tagging support.

I mean, having played with MPX for use in a JIT, it was slower than just manually bounds checking.
