[PATCH][www] Deprecate MPX for GCC 7

[Richard Biener]

Appearantly we forgot to officially deprecate MPX in GCC 7 changes.html.

The following adds the missing note.

Ok?

Thanks,
Richard.

I don't recall deprecating MPX.  I do recall deprecating Cilk+.

There's certainly folks at Intel fixing MPX related issues for GCC.

Ok, maybe I misremember.

Sure.  But bootstrap with MPX is broken since forever and I don't see
anybody using the feature -- plus it's maintainance burden is quite
higher than Cilk+.

Well.  Let's keep it in mind then for GCC 8 deprecation.

Disclaimer: I was asked if we can remove it right now because of its
impact on cgraph code.

Richard.
