Subject: [PATCH -tip v2 10/11] compiler.h: Move function attributes to compiler_types.h
Date: Thu, 21 May 2020 13:08:53 +0200	[thread overview]
Message-ID: <20200521110854.114437-11-elver@google.com> (raw)
In-Reply-To: <20200521110854.114437-1-elver@google.com>

Cleanup and move the KASAN and KCSAN related function attributes to
compiler_types.h, where the rest of the same kind live.

No functional change intended.
