b1fc72630aaa81c8395c3b22ba267d938fe29a2e by Derek Mauro <dmauro@google.com>:
Fix -Wdeprecated-copy warnings from Clang 13.
Example:
error: definition of implicit copy assignment operator for 'UDT' is deprecated because it has a user-declared copy constructor [-Werror,-Wdeprecated-copy]

0422744812b1a2010d9eea5b17fbe89f3441b66b by Evan Brown <ezb@google.com>:
Change the "full table!" asserts in raw_hash_set to use `<= capacity` instead of `< capacity`.
If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert. For example, consider: Group::kWidth = 8, capacity_ = 8, ctrl_ = {kEmpty, 1, 2, 3, 4, 5, 6, 7, kSentinel, kEmpty, 1, 2, 3, 4, 5, 6}. In this case, if we do an unsuccessful lookup with H2 mapping to slot 1, then the first Group will contain {1, 2, 3, 4, 5, 6, 7, kSentinel} so we need to continue to the second Group (at which point seq.index() == 8 == capacity_) to find a kEmpty.
Note: this is a no-op change for now since we never have `capacity % Group::kWidth == 0`.

e7ad047863ae55c9b7aec0753cfc527a4ea614bc by Evan Brown <ezb@google.com>:
Fix a bug in ConvertDeletedToEmptyAndFullToDeleted in which we were copying 1 more cloned control byte than actually exists.
When alignof(slot_type)>1, this wouldn't cause a problem because the extra byte is padding.
Also change loop bounds to not rely on the fact that capacity_+1 is a multiple of Group::kWidth.

1a3ba500fb2c33205854eb9258cd6e0fb1061bca by Martijn Vels <mvels@google.com>:
Change Ring, EXTERNAL and FLAT tag values to be consecutive values
The purpose of this change is to have FLAT = EXTERNAL + 1. Especially in the ring and btree alternative code, there is a common check if a node is a 'plain' edge (EXTERNAL or FLAT), or 'something else'. This change can make that check a single branch, i.e., instead of 'tag == EXTERNAL || tag >= FLAT', we can simply check for 'tag >= EXTERNAL'. Likewise we have some cases where we check for RING, EXTERNAL or FLAT, so we align RING + 1 with EXTERNAL.

0c78e65ca4d85244b106c3f8e24cf268e09e72a3 by Benjamin Barenblat <bbaren@google.com>:
Round a double multiplication before casting it to integer
The code
static_cast<int>(x * y)
(for double x and y) performs a double multiplication into a temporary
that, by standard, may have excess precision. The subsequent cast to int
discards the excess precision. However, the cast may examine the excess
precision during conversion, producing surprising results like
static_cast<int>(1.7 * 10) == 16
on certain systems. Correct this case by explicitly rounding 1.7 * 10
before casting it.
