Subject: [PATCH BlueZ 09/10] build: enable gc/dead code removal
Date: Tue, 16 Jan 2024 13:52:03 +0000 [thread overview]
Message-ID: <20240116-autofoo-v1-9-626f6b54bd06@gmail.com> (raw)
In-Reply-To: <20240116-autofoo-v1-0-626f6b54bd06@gmail.com>
From: Emil Velikov <emil.velikov@collabora.com>
Currently, there's plenty of unused code in most binaries. Enable
-fdata/function-sections, which allows the linker garbage collection to
do its job.
On a maintainer build, this reduces the (unstriped) binaries from 117 to
114MiB.
