Change hash_table to support a comparator type different from the value type stored in the hash table.
Change hash_table to support a comparator type different from the value type stored in the hash table. The 'find' functions now may take a different type from the value type. This requires introducing a second typedef into the Descriptor conceptual type. Change the Descriptor concept to use typedefs value_type and compare_type instead of T. Change all users to match. Add usage documentation to hash-table.h. Tested on x86-64. Index: gcc/ChangeLog 2012-10-25 Lawrence Crowl <crowl@google.com> * hash-table.h: Add usage documentation. (template struct typed_free_remove): Clarify documentation. Rename template parameter. (struct typed_noop_remove): Likewise. (descriptor concept): Change typedef T to value_type. Add typedef compare_type. Use more precise template parameter name, Descriptor instead of Descr. Update users to match. (struct hash_table): Change 'find' parameters to use compare_type instead of the value type. From-SVN: r192823
