Subject: [PATCH] Add -mno-red-zone to CFLAGS for x86-64
Date: Fri, 04 Jul 2014 13:46:55 +0200 [thread overview]
Message-ID: <53B6942F.3040404@siemens.com> (raw)
In-Reply-To: <53B68FE2.9070700@redhat.com>
This is required in order to use the stack in inline assembly (like
pushf; pop reg) without clashing with the compiler's stack assignment.
