* reload.c (find_reloads): Mark new USE insns with QImode.
(find_reloads_toplev, find_reloads_address, subst_reg_equivs,
find_reloads_subreg_address): Likewise.
* regrename.c (note_sets, clear_dead_regs): Abort if pseudos are
encountered.
* reload1.c (reload_combine_note_use): Likewise, inside USEs and
CLOBBERs.
(reload): Make sure there are no USEs with mode other than
VOIDmode. At the end, remove those marked with QImode.
