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.

It’s thus potentially faster, since it doesn’t have to save and restore FPU state. It also is more reflective of developer intent – most developers expect all FPU operations to use the current rounding mode, and having exponential_biased follow that rule seems ideal.

AssertHeld is only enforced for debug builds. The intention here is not to reduce the 'actual' (or 'self') cost of SetCordRep() as it should only be called for sampled cords, but to reduce the cost of a branch and out of line call at the call site. The compiler can now 'perfectly inline' the single branch / store.

Abseil Team	ab21820d47	Export of internal Abseil changes -- e2de21d54c02b6419c57c0f4e2a16b608deca260 by Evan Brown <ezb@google.com>: Remove the InsertEnd benchmark. This benchmark has significantly different possible behaviors that can result in misleading metrics. Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert. PiperOrigin-RevId: 360930639 -- 51f6bb97b9cbdb809c31b77e93ce080ca3cba9ea by Benjamin Barenblat <bbaren@google.com>: Stop testing with double-double random variables On POWER, long double is often represented as a pair of doubles added together (double-double arithmetic). We’ve already special-cased double-double arithmetic in a number of tests, but compiler bugs [1, 2, 3] have now triggered both false positives and false negatives, which suggests testing with double doubles is unlikely to yield useful signal. Remove the special casing and detect if we’re on a double-double system; if so, just don’t test long doubles.

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.

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
