Investigating.
Comment 4 Eric Botcazou 2004-11-28 13:37:19 UTC 
simplify_gen_subreg was seriously shaken recently.  Would you mind updating and
trying again?
Comment 5 James A. Morrison 2004-11-30 12:29:36 UTC 
My bootstrap is now building libjava on sparc64-linux.  I think this bug has
been fixed.
Comment 6 Eric Botcazou 2004-11-30 12:56:29 UTC 
As per James' confirmation.
