This is a very common flag designed to reduce generated code size. It is turned on at all levels of  (except  ) on architectures where doing so does not interfere with debugging (such as x86-64), but you may need to activate it yourself by adding it to your flags. Though the  manual does not specify all architectures it is turned on by using , you will need to explicitly activate it on x86. However, using this flag will make debugging hard to impossible.
