Status of CET support? (Re: [PATCH] D40224:...)

[Pavel Chupin via cfe-commits]

Hi Kostya,
Long time no see. :)
I would estimate that everything (glibc, kernel, loader, simulator)
should be available approx. February 2018 as soon as implementation
finished and tested on our side.
CET is enabled already in GCC, glibc branch with CET is available
(https://sourceware.org/git/?p=glibc.git;a=shortlog;h=refs/heads/hjl/cet/master)
and will be upstreamed as soon as kernel upstream progress made.
