--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-10-22 15:09:05 UTC --- Can you say what -fcompare-debug failures you saw (or was it a bootstrap problem already)? Generally, differences in DECL_UIDs between -g and -g0 should be ok as long as the decls corresponding to decls built at -g0 sort by DECL_UID the same with -g0 and -g, and there should be no differences in between SSA_NAME_VERSION values between -g0 and -g.
