Subject: [U-Boot] [PATCH 2/8] riscv: Enable function sections
Date: Wed, 18 Apr 2018 15:40:24 +0200 [thread overview]
Message-ID: <20180418134030.55127-3-agraf@suse.de> (raw)
In-Reply-To: <20180418134030.55127-1-agraf@suse.de>
The linker can remove sections that are never addressed, so it makes a lot
of sense to declare every function as an individual section.
This reduces the output U-Boot code size by ~30kb for me.
