Abseil Team	9336be04a2	Export of internal Abseil changes -- e7f53dfbf809812e84770217777f81b6308a3084 by Abseil Team <absl-team@google.com>: Add a parameter pack to absl profile to allow profiles to separate dynamic data from static data that is available at constructor-time. Background: `inline_element_size` is effectively constant, but there is a data race between its initialization and its access. We had fixed that race by making inline_element_size atomic. This CL changes `inline_element_size` back to a non-atomic integer, and provides a way for all profiles to provide Register()-time values.

This prevents false positives in the clang-tidy check bugprone-use-after-move; it allows clear() to be called on a moved-from btree_container without any warnings, and the btree_container will thereafter be regarded as initialized again.

PiperOrigin-RevId: 374278107 -- 42f85122407e799183880e0b2e2a71f6d35ee003 by Evan Brown <ezb@google.com>: Use `capacity + Group::kWidth` control bytes instead of `capacity + Group::kWidth + 1`. We don't use the extra byte - we only need the first `capacity` ones that are valid, the one sentinel byte and then `Group::kWidth - 1` cloned control bytes. For example, in `EmptyGroup()`, where capacity is 0, we use `Group::kWidth` control bytes. We need to update set_ctrl() to only mirror `Group::kWidth - 1` bytes instead of `Group::kWidth` bytes. Note: this doesn't actually save memory unless `alignof(value_type)` is one. Also add/update related comments.

In that case, we are supposed to extract the first such key in the container - [reference](https://en.cppreference.com/w/cpp/container/multiset/extract), but we were extracting the first one we found (which was not necessarily the first in the container). Also, optimize internal_lower_bound to not keep searching all the way to the leaf if it finds an equivalent key on an internal node and we can't have multiple equivalent keys for the lookup key.

This is a change based on an observation in RPC benchmarks that shows significant cycles being spent in waking up a thread, 99.8% of which was on cache misses. Investigating this a bit more, it turns out to be due to sharing the cache line with the waiter state. To fix this issue, the following changes are introduced: - Reorder fields in PerThreadSync so that it fits in a single cache line The size of this structure was 80 bytes before this change. Note: Manually inspected all booleans to make sure they are not modified by multiple threads concurrently.

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
