Subject: [PATCH v2 06/11] tools/nolibc: aarch64: use C89 comment syntax
Date: Thu, 06 Apr 2023 21:54:52 +0000	[thread overview]
Message-ID: <20230328-nolibc-c99-v2-6-c989f2289222@weissschuh.net> (raw)
In-Reply-To: <20230328-nolibc-c99-v2-0-c989f2289222@weissschuh.net>

Most of nolibc is already using C89 comments.
