Abseil Team	75691f1c32	Fix "unsafe narrowing" warnings in absl, 6/n. Addresses failures with the following, in some files: -Wshorten-64-to-32 -Wimplicit-int-conversion -Wsign-compare -Wsign-conversion -Wtautological-unsigned-zero-compare (This specific CL focuses on .cc files in strings/internal/.)

Abseil Team	58e042da92	Export of internal Abseil changes -- 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).

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	3 years ago

PiperOrigin-RevId: 372339945 -- 9a61504867ba0eccc5046d7333090fbe3439cdd9 by Abseil Team <absl-team@google.com>: Add benchmark for BlockingCounter PiperOrigin-RevId: 372246068 -- 91ee87e6de09fc62970667ee52654c9dcf7c478d by Evan Brown <ezb@google.com>: In absl::StrSplit, support btree_multimap, and other non-std::multimap-multimaps by supporting any map type that returns iterator from insert(). Also: - Use emplace() instead of insert() when available, not just for std::(multi)map - we can potentially change some string copies to moves this way. - We no longer need the Insert class so remove it.

Abseil Team	a4798817e8	Export of internal Abseil changes -- 197bd3e5e315f408bdc2f7111a0652be7f47609f by Jorg Brown <jorg@google.com>: ConvertibleToStringView wastes a lot of cycles initializing a std::string member that it never uses. This CL restricts ConvertibleToStringView to just the cases that don't nned a std::string member, and uses an additional StrSplit overload to catch when users pass a temporary string. This makes StrSplit() 0-30% faster depending on the use case.

Abseil Team	e9b9e38f67	Export of internal Abseil changes -- 0e3e8be75b3ab243991c9b28a27623d86e4511e6 by Abseil Team <absl-team@google.com>: Add constructor overloads with signature (Mutex*, const Condition&) to MutexLock, ReaderMutexLock, WriterMutexLock, ReleasableMutexLock, MaybeMutexLock. These overloads call Mutex::LockWhen, Mutex::ReaderLockWhen, Mutex::WriterLockWhen. Using the guard classes with these new constructors replaces both manual LockWhen/Unlock sequences and the less-efficient, but popular current pattern of "absl::MutexLock lock(&mu); mu.Await(cond);".

Today, Bazel detects clang and automatically sets the compiler string to "clang".

This fixes this problem for these users. As a reminder, [we still recommend passing string_view by value for function parameters](https://abseil.io/tips/1) as it generates less code.

Abseil Team	768eb2ca28	Export of internal Abseil changes -- 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: 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
