Subject: [PATCH master 07/14] RISC-V: restrict GCC optimization some more
Date: Tue, 11 Apr 2023 09:14:29 +0200 [thread overview]
Message-ID: <20230411071436.1630752-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230411071436.1630752-1-a.fatoum@pengutronix.de>
Some of these we are already setting for ARM and all of them are already
in use by the Linux RISC-V arch Makefile.
