Subject: [PATCH 44/46] scripts/bloat-o-meter, lto: handle gcc LTO
Date: Mon, 14 Nov 2022 12:43:42 +0100	[thread overview]
Message-ID: <20221114114344.18650-45-jirislaby@kernel.org> (raw)
In-Reply-To: <20221114114344.18650-1-jirislaby@kernel.org>

From: Andi Kleen <ak@linux.intel.com>

gcc LTO can add .lto_priv postfixes to symbols. Ignore those in
bloat-o-meter to allow comparison of non-LTO with LTO kernels.
