Zdenek, can you elaborate on why CSE needs fixing? cse does not handle autoincrements. I have no idea what's the problem there, it is just what I was told when I asked for the possibility to move the autoinc creation pass last time. Anyone has more precise information about the nature of the problem? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19078
