Subject: [PATCH v7 2/2] tools_def: add -fno-omit-frame-pointer to GCC48_{IA32,X64}_CC_FLAGS
Date: Wed, 30 Nov 2022 10:44:14 +0100 [thread overview]
Message-ID: <20221130094414.1983787-3-kraxel@redhat.com> (raw)
In-Reply-To: <20221130094414.1983787-1-kraxel@redhat.com>
Fixes problems due to code assuming it runs with frame pointers and thus
updates rbp / ebp registers when switching stacks.
