Subject: [PATCH v4 3/6] tools include: Add some common function attributes
Date: Fri, 28 Jul 2023 00:26:14 +0100 [thread overview]
Message-ID: <20230728-arm64-signal-memcpy-fix-v4-3-0c1290db5d46@kernel.org> (raw)
In-Reply-To: <20230728-arm64-signal-memcpy-fix-v4-0-0c1290db5d46@kernel.org>
We don't have definitions of __always_unused or __noreturn in the tools
version of compiler.h, add them so we can use them in kselftests.
