Derek Mauro	d2c5297a3c	Update GoogleTest version used by Abseil As part of this update, GoogleTest is now using the Abseil flags implementation, and the flags usage_test needs to be modified to pass. If building with bazel and --define=absl=1 to force GoogleTest to use Abseil, a WORKSPACE dependency on the abseil branch of the RE2 project is now required.

Abseil Team	a05366d851	Export of internal Abseil changes -- 04cb3b22497190170aa5b774e98080c5de2ba60b by Abseil Team <absl-team@google.com>: Alternative bit mixer for LowLevelHash on ARM LowLevelHash's bit-mixer is inefficient on ARM because it calculates a 128-bit product of two 64-bit numbers. On ARM, this requires a sequence of two instructions with a high combined latency and poor throughput. This change provides alternative bit-mixing code for ARM that uses only 64-bit arithmetic (multiplication, xor, and left-shifts) and speeds things up considerably. The bit-mixing code for ARM was inspired by by Woothash[1] and xxh3[1]. Once I landed on a sequence of operations that provided good mixing, I used a test harness to search for the combination of shift / rotate factors that provided the best mixing, as indicated by SMHasher hash quality tests. The new mixing code passes 13 out of 15 of the hash quality test suites in SMHasher, with the two failures being in the noise range: e.g. 1 collision vs. zero expected in a keyset of ~8m keys.

If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert.

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.

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.

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.

Abseil Team	62ce712ecc	Export of internal Abseil changes -- b927776da818c674a674e46a7bbbdd54170a0ad3 by Todd Lipcon <tlipcon@google.com>: Include priority in the calculation of mutex waiter equivalence This changes the behavior of the absl::Mutex wait list to take into account waiter priority when creating "skip chains". A skip chain on the wait list is a set of adjacent waiters that share some property and enable skipping during traversal. Prior to this CL, the skip chains were formed of waiters with the same wait type (e.g. exclusive vs read) and Condition. With this CL, the priority is also taken into account. This avoids O(n) behavior when enqueueing a waiter onto a wait list where the oldest waiter is at a lower priority than the waiter to be enqueued. With the prior notion of equivalence class, a skip chain could contain waiters of different priority, so we had to walk the linked list one-by-one until finding the appropriate insertion point. With the new equivalence class computation, we can skip past all of the equivalent waiters to find the right insertion point. This gives a substantial improvement to the enqueue performance in the case where there's already a waiter at lower priority. Note that even though this code path isn't a hot one, it's performed while holding the Mutex's spinlock, which prevents other threads from unlocking the Mutex, so minimizing the time under the critical section can have "knock-on" throughput benefits.

The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

Stealing string data is faster, but it creates a long chunk, which leads to a higher more memory usage if its subcords are created and outlive the whole Cord. These functions revert to copying the data if any of the following conditions holds: - string size is at most kMaxBytesToCopy (511), to avoid the overhead of an external chunk for short strings; - less than half of string capacity is used, to avoid pinning to much unused memory.

Abseil Team	768eb2ca28	Export of internal Abseil changes -- f012012ef78234a6a4585321b67d7b7c92ebc266 by Laramie Leavitt <lar@google.com>: Slight restructuring of absl/random/internal randen implementation. Convert round-keys.inc into randen_round_keys.cc file. Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts. Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

This fixes the Abseil Flags for big endian platforms. PiperOrigin-RevId: 311844448 -- bdbe6b5b29791dbc3816ada1828458b3010ff1e9 by Laramie Leavitt <lar@google.com>: Change many distribution tests to use pcg_engine as a deterministic source of entropy. It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests. Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values. This changelist does the latter. PiperOrigin-RevId: 311840096 GitOrigin-RevId: f012012ef78234a6a4585321b67d7b7c92ebc266 Change-Id: Ic84886f38ff30d7d72c126e9b63c9a61eb729a1a	5 years ago
