-- 84bcdcd9497d1ec989f50c8dee93f656507c7bd6 by Abseil Team <absl-team@google.com>: Reduce length of the `flat_hash_map<std::string, V>` type name in order to reduce binary bloat. PiperOrigin-RevId: 391560997 -- 5f49bd435e066989851dc045c7786ef400413f66 by Greg Falcon <gfalcon@google.com>: Claim a bit from the Cord refcount for future use. Also rename the increasingly-inaccurately named "Refcount" class to "RefcountAndFlags". In optimized builds, this adds an extra mask instruction to decrement and test operations, but no new branches. Future flags can be added at no extra cost. Each additional flag will of course reduce the range of our refcount, but even with the bit added, we still support refcounts of 500 million.

-- 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.

PiperOrigin-RevId: 311999699 -- 64756f20d61021d999bd0d4c15e9ad3857382f57 by Gennadiy Rozental <rogeeff@google.com>: Switch to fixed bytes specific default value. 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 |
