Patch candidate for #c15
I've got a patch for #c15.
@Richi: Is it something you expected?
I see the following speed up:
w/ verification: 9.9 -> 8.7s
w/o verification: 4.8 -> 3.7
Now perf report looks like:
5.41% cc1plus cc1plus [.]
hash_table<hash_map<gimple*, int,
simple_hashmap_traits<default_hash_traits<gimple*>, int> >::hash_entry, false,
xcallocator>::find_with_hash
