--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
constraint_operands before reload doesn't accept a pseudo for "m" constraint,
only during reload:
                /* Before reload, accept what reload can turn into mem.  */
                else if (strict < 0 && CONSTANT_P (op))
                  win = 1;
                /* During reload, accept a pseudo  */
                else if (reload_in_progress && REG_P (op)
                         && REGNO (op) >= FIRST_PSEUDO_REGISTER)
                  win = 1;
Wonder if it would be ok to change that reload_in_progress to !reload_completed
or !strict or something similar, or, if not, whether we shouldn't have some
other memory constraint on i?86 or everywhere that would be accept a pseudo for
strict < 0 instead of only for reload_in_progress.
