[Bug tree-optimization/35639] [4.3/4.4 Regression] -fprofile-generate = huge SCCs for PRE

------- Comment #10 from bonzini at gnu dot org  2009-02-05 09:01 -------
I get some SCCs that have 1500+ values in them.  That is quite expensive to
maintain.

345,334,000  iterative_hash_hashval_t
199,259,509  ???:???
151,133,289  iterative_hash_expr
111,911,577  bitmap_bit_p
 96,901,657  htab_find_slot_with_hash
 93,662,766  get_expr_value_id
 64,328,952  bitmap_set_bit
