Subject: [GIT PULL] Clang feature updates for v5.14-rc1 (take 2)
Date: Tue, 29 Jun 2021 13:55:20 -0700	[thread overview]
Message-ID: <202106291354.CE55889CF4@keescook> (raw)

Hi Linus,

Please pull these Clang feature updates for v5.14-rc1 (take 2). This is
everything except the big PGO portion from the original pull request
and includes an additional CFI fix that had gotten lost.

Thanks!

-Kees
