than assume all emits go through df_insns_modify.
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>
* sbitmap.h (EXECUTE_IF_SET_IN_SBITMAP_REV): New macro, needed for
dataflow analysis.
