Abseil Team	60be12ed98	Export of internal Abseil changes -- 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] PiperOrigin-RevId: 380058303 -- 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`. PiperOrigin-RevId: 380033480 -- 40628c34d540356de65fabb16c1439c0ec7a0764 by Abseil Team <absl-team@google.com>: Drop out-of-date documentation about `absl::FixedArray`'s allocator support PiperOrigin-RevId: 379811653 -- e7ad047863ae55c9b7aec0753cfc527a4ea614bc by Evan Brown 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. PiperOrigin-RevId: 379311830 -- 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. PiperOrigin-RevId: 379291576 -- 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.

Abseil Team	4fd9a1ec50	Export of internal Abseil changes -- 03700706d80f0939e2b5b8c02a326f045b643730 by Abseil Team <absl-team@google.com>: Reduced latency and code-size of some InlinedVector methods: 1. Simpler fast path for push_back/emplace_back. 2. Do not inline slow path of push-back/emplace_back. 3. Simplify resize implementation. Performance: A simple benchmark that does the following per iteration: ``` push_back on an InlinedVector<int64> push_back on an InlinedVector<bool> ``` Sees iteration time go from 4.3ns to 2.8ns and code size shrink from 1129 bytes to 175 bytes.

The #ifdef to produce calls to __sanitizer_unaligned_load16 etc were needed in past versions of this code, when we were lying to the compiler about the alignment of the loads/stores, by using a reinterpret_cast. However, a year ago, absl switched to simply use memcpy. Sanitizers support this correctly by default, nothing extra is required.

PiperOrigin-RevId: 314600027 -- 6c452aa1ee7e46ab941ba7d1fa636da8ea3d7370 by Laramie Leavitt <lar@google.com>: Remove the MockingBitGenBase base class in favor of type-erasure in BitGenRef. In Abseil random, mocking was split across two different classes, MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a test-only library that we don't link into production, so MockingBitGenBase provided a low-overhead scaffold used to lookup mocks when in test code, but which is unused in production code. That has been replaced by type-erasure which looks for a method named CallImpl with the correct signature. Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet. Rename CallImpl to InvokeMock() Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

PiperOrigin-RevId: 312931131 -- 96225212a9f5fbd0b38c71fe65539164992c7c3b by Laramie Leavitt <lar@google.com>: Remove random/internal/distributions.h This file was something of an historical artifact.

PiperOrigin-RevId: 312707974 -- 34484d18dfb63a0a7ad6e2aaeb570e33592968be by Abseil Team <absl-team@google.com>: Let Cord::Cord(string&&), Cord::operator=(string&&), Cord::Append(string&&), and Cord::Prepend(string&&) steal string data and embed it into the Cord as a single external chunk, instead of copying it into flat chunks (at most 4083-byte each). 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.

Convert round-keys.inc into randen_round_keys.cc file. Consistently use a 128-bit pointer type for internal method parameters.

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
