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.
