* hashtab.h (struct htab): Add member return_allocation_failure.
(htab_try_create): New prototype. Mention which functions may
return NULL when this is used.
From-SVN: r37246
* hashtab.h (hashval_t): New type.
(htab_find_with_hash): Use it as an argument.
(htab_find_slot_with_hash): Likewise.
* hashtab.c (find_empty_slot_for_expand): Use hashval_t for hash
codes.
(htab_find_with_hash): Likewise.
(htab_find_slot_with_hash): Likewise.
From-SVN: r32842
* hashtab.c: Remove debugging variables (all_searches,
all_collisions, all_expansions). Delete
all_hash_table_collisions.
(create_hash_table, delete_hash_table, empty_hash_table,
find_hash_table_entry, remove_element_from_hash_table_entry,
clear_hash_table_slot, traverse_hash_table, hash_table_size,
hash_table_elements_number, hash_table_collisions): Rename to:
htab_create, htab_delete, htab_empty, htab_find_slot,
htab_remove_elt, htab_clear_slot, htab_traverse, htab_size,
htab_elements, htab_collisions.
(htab_find): New function, handles common case where you don't
plan to add or delete an entry.
(htab_expand): Don't create a whole new table, just a new
entry vector.
(htab_find_slot): Simplify logic.
* hashtab.h (hash_table_t): Rename to htab_t.
(struct hash_table): Rename to struct htab. Shorten element
names. Reorder elements by size.
(htab_hash, htab_eq, htab_trav): New typedefs for the callback
function pointers.
(hash_table_entry_t): Discard; just use void * for element
type.

* hashtab.c (find_hash_table_entry): When returning a
DELETED_ENTRY slot, change it to EMPTY_ENTRY first.
(clear_hash_table_slot): New function which deletes an entry
by its position in the table, not its value.
(traverse_hash_table): New function which calls a hook
function for every live entry in the table.
* hashtab.h: Give hash_table_t a struct tag. Add prototypes
for clear_hash_table_slot and traverse_hash_table. Correct
prototype of all_hash_table_collisions.
