(df_reg_table_realloc): Make size at least as large as max_reg_num().
(df_insn_table_realloc): Size argument now is absolute, not relative.
Changed all callers.
* gengtype.c (main): Add the pseudo-type "HARD_REG_SET".

involving subregs with invalid mode changes, when
CLASS_CANNOT_CHANGE_MODE is defined.

2001-07-26 Daniel Berlin <dan@cgsoftware.com>
* regclass.c (reg_scan_mark_refs): When we increase REG_N_SETS,
increase REG_N_REFS (like flow does), so that regclass doesn't
think a reg is useless, and thus, not calculate a class, when it
really should have.
2001-01-28 Daniel Berlin <dberlin@redhat.com>
