Subject: [RFC PATCH 02/28] Documentation: Bump minimum GCC version to 8.1
Date: Wed, 25 Sep 2024 17:01:02 +0200	[thread overview]
Message-ID: <20240925150059.3955569-32-ardb+git@google.com> (raw)
In-Reply-To: <20240925150059.3955569-30-ardb+git@google.com>

From: Ard Biesheuvel <ardb@kernel.org>

Bump the minimum GCC version to 8.1 to gain unconditional support for
referring to the per-task stack cookie using a symbol rather than
relying on the fixed offset of 40 bytes from %GS, which requires
elaborate hacks to support.

Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
