PiperOrigin-RevId: 428076422 -- 6a90d18477cc3a6de84282b6e38d6f294aa72748 by Evan Brown <ezb@google.com>: In sanitizer mode, add generation integers to b-tree nodes and iterators and validate that iterators have not been invalidated already when they're used. Even though generation integers are stored in all nodes, we only use the one stored in the root node for validation. The reason we keep one in all the nodes is that nodes can become a root node after they are allocated. Also change the order of args in init_leaf to not violate the style guide. PiperOrigin-RevId: 428054226 -- ede4a0f676f43e7003fd2599c263d55222e760ba by Martijn Vels <mvels@google.com>: Physically remove CordRepConcat This CL removes all uses of CordRepConcat. This change is executed by removing all the dead 'btree_enabled()' and 'IsConcat' branches, and all subsequent dead code. This change explicitly does not optimize any of the remaining code other than the most trivial ones such as removing 'stack' loop vars and loops. PiperOrigin-RevId: 428002308 -- 7cc83d96118149cf1aa1258a066b8fd4517df5f6 by Evan Brown <ezb@google.com>: Change btree_iterator from a struct to a class. Motivation: btree_iterator has private members and invariants so it should be a class. Also merge two private sections. PiperOrigin-RevId: 427768836 -- 524d478b0af422e1a867a8823d9fbad149030360 by Martijn Vels <mvels@google.com>: Physically block the creation of new CordRepConcat nodes. This change removes CordRepConcat creation, issuing a FATAL errors on the (practically impossible) call path on broken invariants. This change is deliberately limited in impact, subsequent changes will be more voluminous ripping out the (now dead) CordRepConcat code. PiperOrigin-RevId: 427741022 -- e21eb354c1bb358ea8b64d0e3fbb378e87b8b8c4 by Derek Mauro <dmauro@google.com>: Update the implementation of ABSL_DEPRECATED to work with GCC, and recommend using the standard attribute [[deprecated]] for C++14 and newer GCC users that are experiencing new warnings can silence them with -Wno-deprecated-declatations. GCC users that want to see the warnings but not error on them can use -Wno-error=deprecated-declarations. PiperOrigin-RevId: 427228952 -- 0ab4ee5660f3a072054dc4ab5056925c26977c7a by Laramie Leavitt <lar@google.com>: Change comment to avoid overflow.

This change removes the creation and uses of CordRepConcat in unit tests, and replaces some remaining CONCAT constants with IsConcat() to make subsequent teardown of CordrepConcat uses easier. PiperOrigin-RevId: 426932694 -- fd590f7e849ba8c5395c589ed3f762cd00affdc8 by Abseil Team <absl-team@google.com>: Replace NULL and 0 with nullptr.

-- 1620e8ffaa93ef24510ca60c7fff2a07248ac9f6 by Abseil Team <absl-team@google.com>: Update comment. PiperOrigin-RevId: 382858259 -- 20db116f28469149d10e0f7f8b976cb903dd4879 by Gennadiy Rozental <rogeeff@google.com>: Add benchmark running on multiple flags. Update size_tester to include cost of absl::GetFlag call. Add size_tester invocation for bool flag. New benchmark better represent GetFlag usage. PiperOrigin-RevId: 382820341 -- 2e097ad3811c4e329f75b98877a5e74c1d3d84fd by Abseil Team <absl-team@google.com>: Avoid 64x64->128 multiplication in absl::Hash's mix on AArch64 On AArch64, calculating a 128-bit product is inefficient, because it requires a sequence of two instructions to calculate the upper and lower halves of the result. So calculate a 64-bit product instead. Making MultType 64-bits means the upper 32 bits of the result do not participate in shift/xor, but the add/multiply gives us sufficient mixing. PiperOrigin-RevId: 382625931 -- f3ae3f32cb53168c8dc91b766f2932dc87cec503 by Abseil Team <absl-team@google.com>: Remove homegrown Round implementation absl/time/duration.cc defined a Round implementation to accommodate old versions of MSVC that lacked std::round(long double). Abseil no longer supports those MSVCs, so we don’t need the homegrown implementation anymore. Remove it, and replace calls to it with std::rint. PiperOrigin-RevId: 382605191 -- a13631c91bf5478289e1a512ce215c85501a26f7 by Martijn Vels <mvels@google.com>: Move the Consume() conversion functions out of cord_rep_ring into cord_rep_consume. This makes these functions generic, so we can repurpose these for the new Btree conversion functions. PiperOrigin-RevId: 382594902 -- 7394c737500c2d8371fcf913b21ad1b321ba499d by Benjamin Barenblat <bbaren@google.com>: Remove homegrown Round implementation absl/time/duration.cc defined a Round implementation to accommodate old versions of MSVC that lacked std::round(long double).

PiperOrigin-RevId: 382569900 -- d72a761f43dc5c9b9510c3a1363177ed26646b5d by Abseil Team <absl-team@google.com>: Prefer `getentropy` for Emscripten. It needs a different header, so I've separated it out from the GLIBC check above. PiperOrigin-RevId: 382332475 -- 74e261dbb467741b2ddd8b490e04c531fdd2f559 by Martijn Vels <mvels@google.com>: Add BTREE tag for CordRepNode implementing a Btree cord. This change only forward declared the CordRepBtree class (not implemented yet) and defines the enum value BTREE. While RING and BTREE should never co-exist, we define a new value for BTREE so as not to make transitioning between RING and BTREE harder than it needs to be. This changes shifts the FLAT value / computation from FLAT = 4 to FLAT =5 PiperOrigin-RevId: 382326710 GitOrigin-RevId: 1620e8ffaa93ef24510ca60c7fff2a07248ac9f6 Change-Id: Ia8f99dde3874808f56062bd37ab3e63764099734
