Subject: [PATCH v2 1/1] BaseTools: disable stack protector (gcc, AARCH64)
Date: Wed, 20 Apr 2022 10:16:03 +0200 [thread overview]
Message-ID: <20220420081603.27503-2-osteffen@redhat.com> (raw)
In-Reply-To: <20220420081603.27503-1-osteffen@redhat.com>
Explicity disable the stack protection with
-fno-stack-protection for builds using GCC on
AARCH64.
The gcc on Ubuntu enables -fstack-protector-strong
by default starting with Ubuntu 21.10.
GenFw fails if stack protection is enabled.
