cfi-icall is a form of Control-Flow Integrity for indirect function calls implemented by llvm. It is enabled with a -fsanitize flag. iotests are currently disabled when -fsanitize options is used, with the exception of SafeStack. This patch implements a generic filtering mechanism to allow iotests with a set of known-to-be-safe -fsanitize option. Then marks SafeStack and the new options used for cfi-icall safe for iotests Signed-off-by: Daniele Buono <dbuono@linux.vnet.ibm.com> Message-Id: <20201204230615.2392-4-dbuono@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
