Subject: [PATCH v2 03/11] ARM: asm: setjmp: annotate setjmp/longjmp for GCC
Date: Mon, 1 Mar 2021 12:00:58 +0100 [thread overview]
Message-ID: <20210301110106.3764-4-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210301110106.3764-1-a.fatoum@pengutronix.de>
To avoid invalid optimizations and to enable warnings, GCC must be told
that setjmp and longjmp are to be handled specially. Add the missing
attributes.
