Aligning small_buffer in struct unix_stream would help performance. As an array
of char, it can and does appear with byte alignment.

Is there a way to say that char * buffer will always be aligned? In that case this could still make sense. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |tobi at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21226 ^ permalink raw reply [flat|nested] 4+ messages in thread
