Subject: [PATCH 3/5] sim/ppc: mark device_error function as ATTRIBUTE_NORETURN
Date: Wed, 12 Oct 2022 13:38:33 +0100 [thread overview]
Message-ID: <39eeb655ef7a1a8b3ea3c2f120e7d67693ec3f93.1665578246.git.aburgess@redhat.com> (raw)
In-Reply-To: <cover.1665578246.git.aburgess@redhat.com>
The device_error function always ends up calling the error function,
which is itself marked as ATTRIBUTE_NORETURN, so it makes sense that
device_error should also be marked ATTRIBUTE_NORETURN.
Doing this resolves a few warnings from hw_ide.c about possibly
uninitialized variables - the variables are only uninitialized after
passing through a call to device_error, which obviously means the
variables are never really used uninitialized, the simulation will
terminate with the device_error call.
