Subject: [PATCH 3/4] RISC-V: Define and use GOT entry size constants for TLS.
Date: Fri, 18 Aug 2023 03:08:36 +0900	[thread overview]
Message-ID: <20230817180852.121628-5-ishitatsuyuki@gmail.com> (raw)
In-Reply-To: <20230817180852.121628-2-ishitatsuyuki@gmail.com>

As the size calculation is split by global and local symbols, using a
shared constant definition for its size improves clarity.
