Abseil Team	bf31a10b65	Export of internal Abseil changes -- 93c607726d663800b4bfa472cba043fd3f5d0e97 by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 389158822 -- 55b3bb50bbc168567c6ba25d07df2c2c39e864af by Martijn Vels <mvels@google.com>: Change CordRepRing alternative implementation to CordRepBtree alternative. This changes makes CordRepBtree (BTREE) the alternative to CordRepConcat (CONCAT) trees, enabled through the internal / experimental 'cord_btree_enabled' latch. PiperOrigin-RevId: 389030571 -- d6fc346143606c096bca8eb5029e4c429ac6e305 by Todd Lipcon <tlipcon@google.com>: Fix a small typo in SequenceLock doc comment PiperOrigin-RevId: 388972936 -- e46f9245dce8b4150e3ca2664e0cf42b75f90a83 by Martijn Vels <mvels@google.com>: Add 'shallow' validation mode to CordRepBtree which will be the default for internal assertions.

Abseil Team	b06e719ee9	Export of internal Abseil changes -- 007ce045d5d38a727ededdb5bf06e64785fd73bd by Martijn Vels <mvels@google.com>: Add `cord_enable_btree` feature flag (default false). PiperOrigin-RevId: 383729939 -- 98e7dc6a0407b0fd7b8713d883cdb3a766e0583d by Benjamin Barenblat <bbaren@google.com>: Eliminate some byte swapping from randen_slow Stop swapping bytes when serializing randen_slow’s Vector128 into and out of memory. Instead, simply index different bytes in the AES round function. This requires byte swapping the te{0..3} lookup tables, but it produces an 8% speedup on my Xeon W-2135. PiperOrigin-RevId: 383689402 -- 180b6bf45049188840d439b16a28e6b968669340 by Evan Brown <ezb@google.com>: Minor simplification in drop_deletes_without_resize() - save probe_offset outside the lambda. Also, add some consts, avoid an auto, and use lambda capture by value instead of reference. I realized that the compiler can already optimize this - https://godbolt.org/z/Wxd9c4TfK, but I think this way makes the code a bit clearer. PiperOrigin-RevId: 383646658 -- 781706a974c4dc1c0abbb6b801fca0550229e883 by Martijn Vels <mvels@google.com>: Change storage to contain 3 bytes. As per the comments in the code, this allows us to utilize all available space in CordRep that may otherwise be 'lost' in padding in derived clases. For the upcoming CordrepBtree class, we want a strong guarantee on having a 64 bytes aligned implementation.

This eliminates some code and improves support for big-endian platforms.

PiperOrigin-RevId: 352771994 -- 4bd36dda61760785844f0f29f26d90cc18046f75 by Abseil Team <absl-team@google.com>: Optimize InlineData representation for cord sampling (cordz) This CL changes InlineData to allow us to store a (future) Cordz Info pointer directly into the inline representation: - make InlineData a class that provides a public API to set the active union members (tree or chars) and safely access that data. - change 'tree' and 'profiled' bits to be the 2 least significant bits, allowing us 62 continquous bits for storing a Cordz Info pointer.

Abseil Team	1918ad2ae3	Export of internal Abseil changes -- 0bfa836596a9c787a2f0bdc283011dd1f6810c6e by Benjamin Barenblat <bbaren@google.com>: Ignore missing CPU frequency on more architectures Linux on MIPS, PA-RISC, RISC-V, and SystemZ doesn’t expose the nominal CPU frequency via /sys, so don’t worry if `NominalCPUFrequency` returns 1.0 on those platforms. Some POWER machines expose the CPU frequency; others do not. Since we can’t predict which type of machine the tests will run on, simply disable testing for `NominalCPUFrequency` on POWER. PiperOrigin-RevId: 347079873 -- 492b6834ed4a07cbc3abccd846f7e37d8c556ee5 by Benjamin Barenblat <bbaren@google.com>: Use ABSL_HAVE_THREAD_LOCAL macro instead of copying code Reduce code duplication by checking the ABSL_HAVE_THREAD_LOCAL macro instead of copying code from base/config.h. PiperOrigin-RevId: 347079561 -- 8d656efce4da9cb032094377e58493d98427a536 by Abseil Team <absl-team@google.com>: Rollback PiperOrigin-RevId: 347078779 -- 221bc69ec6dd7e2777ffcff6942584f979ef6382 by Abseil Team <absl-team@google.com>: Add flag for 'shallow subcord' feature for experimental ring buffer rollout There is a potential trade-off of CPU cost vs over-sharing cord data for subcord of large cords. This flag allows making subcords shallow for ringbuffers (with a potential larger waste of referenced source cords), which allows us to make subcord fast for this apps that do no persist (unmodified / plain copied) sub cords. This change also introduces constants for the default settings, intended to keep the internal cord settings concistent with external flags.

PiperOrigin-RevId: 346815392 -- 35cae74a977f258e81dfbe925fb5a34cb6632036 by Gennadiy Rozental <rogeeff@google.com>: Eliminate unnecessary access to the global vars. PiperOrigin-RevId: 346777168 -- e7e786c243069060f5d6c1c945decb4b0b83f95b by Andy Getzendanner <durandal@google.com>: Internal change. PiperOrigin-RevId: 346685656 -- 4ccd41c48f1a83cfa20b3ea534f743dd7d788376 by Abseil Team <absl-team@google.com>: Move CordRep Ref() and Unref() logic into cord_internal.h This change moves Ref() and Unref() logic out of cord.cc into cord_internal. 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.
