------- Comment #8 from jakub at gcc dot gnu dot org 2010-03-25 21:06 ------- Oops, sorry, forgot that -fdump-final-insns=XX does emit decl uids into the dump, unless -fcompare-debug=-gtoggle is also passed to cc1. So I was comparing what -fcompare-debug actually is not comparing. The alias differences are the only real ones, looking into it.
