Adjust a few sites accordingly to indicate how to handle the RISC-V architecture. PiperOrigin-RevId: 390631894 -- 5fa3a0961bf3dd0799c048956a0128f7b8113f1e by Samuel Benzaquen <sbenza@google.com>: Rename the buffer hash function to LowLevelHash.

PiperOrigin-RevId: 387585161 -- 206d298e2bccb998731995cb05717b31fa9d90ec by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 387577465 -- f07fafe8a400a4f5dfef186d1a3b61fb7f709fe5 by Abseil Team <absl-team@google.com>: This change adds debug-build enforcement that the inputs to absl::c_set_intersection are sorted, which is a prerequisite of std::set_intersection and required for correct operation of the algorithm. PiperOrigin-RevId: 387446657 -- 2ca15c6361bb758be7fb88cae82bf8489b4d3364 by Abseil Team <absl-team@google.com>: Change BadStatusOrAccess::what() to contain status_.ToString() This ensures that on uncaught exception propagation that would cause program termination, the message contains information on the error which caused the failure. Lazy initialization of what_ is a value judgement: if most callers are expected to call status() not what(), lazy initialization is correct. If most callers are expected to call what(), it should be initialized on construction to avoid atomic operation overhead. PiperOrigin-RevId: 387402243 -- 3e855084e104dc972a0c4385395e6d8e8465127f by Gennadiy Rozental <rogeeff@google.com>: LSC: Standardize access to GoogleTest flags on GTEST_FLAG_GET/GTEST_FLAG_SET This change is necessary to move Googletest flags out of the testing:: namespace without breaking code. These new macros will continue to be required for code that needs to work both inside Google's monorepo and outside in OSS, but can be used anywhere inside the monorepo.

This will prevent callers from passing arguments, such as std::atomic<T>. This change is an API break. Information and a tool to fix issues can be found at https://abseil.io/docs/cpp/tools/upgrades/duration-conversions PiperOrigin-RevId: 387153494 -- 786063e438ab6a55ac4baa88ad4d20a8293be52a by Evan Brown <ezb@google.com>: Make ctrl_t be an enum class.

PiperOrigin-RevId: 387120717 -- 7e537aabec1c255d6e7c9d21232c597c1c2077bf by Evan Brown <ezb@google.com>: Add some missing `const` keywords to ctrl_t* function parameters. PiperOrigin-RevId: 386976062 -- da53ac6d91cabd951e81dd0a145e1e52b918955f by Martijn Vels <mvels@google.com>: Change Seek and InitOffset to return nullptr instead of assert / fail. This makes it consistent with the rest of the API (Next, Previous, Skip) and hardens it against invariants that are harder (or less likey) to be upheld correctly by the caller.

PiperOrigin-RevId: 381276748 -- da32624792d2948fe83d0ce58794d505799ab5d0 by Benjamin Barenblat <bbaren@google.com>: s/round/rint/ in exponential_biased `rint` differs from `round` in that it uses the current FPU rounding mode. It’s thus potentially faster, since it doesn’t have to save and restore FPU state. It also is more reflective of developer intent – most developers expect all FPU operations to use the current rounding mode, and having exponential_biased follow that rule seems ideal.

PiperOrigin-RevId: 380714572 -- f8f4dee12cfd02559bf741ad6b06f10ac0c48c73 by Abseil Team <absl-team@google.com>: Fix shadow member warnings in randen_hwaes.cc These happen when attempting to use abseil in github.com/google/benchmark. The project sets -Wshadow. The warning is due to the name of the Vector128 ctor parameter. Using v instead, which I see used elsewhere (e.g. line 290) PiperOrigin-RevId: 380704197 -- 2e1a09e9cb1239485715acb4828d9b4799fcfbb5 by Tom Manshreck <shreck@google.com>: Add more precise documentation for AbslParseFlag declarations in the Time API PiperOrigin-RevId: 380649107 -- 153e5f7a960c03e4161c03737a0ff18ba377ff73 by Evan Brown <ezb@google.com>: Make the number of control bytes a constant. We use a constexpr function because we need to support C++11, which doesn't have inline variables. The motivation is to avoid future bugs where the number changes and we forget to update all the places it's used. This CL should be a no-op.

Identify tests that are sensitive to the x87, and skip them when we’re on 32-bit Intel.

I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path. This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider. The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider. The default paths for the distributions are either the bounds or a median value.

In particular, we optimize for empty vectors in both cases. Added a couple of benchmarks that copy either an InlVec<int64> or an InlVec<InlVec<int64>>. Speed difference: ``` BM_CopyTrivial/0 0.92ns +- 0% 0.47ns +- 0% -48.91% (p=0.000 n=11+12) BM_CopyTrivial/1 0.92ns +- 0% 1.15ns +- 0% +25.00% (p=0.000 n=10+9) BM_CopyTrivial/8 8.57ns +- 0% 10.72ns +- 1% +25.16% (p=0.000 n=10+12) BM_CopyNonTrivial/0 3.21ns +- 0% 0.70ns +- 0% -78.23% (p=0.000 n=12+10) BM_CopyNonTrivial/1 5.88ns +- 1% 5.51ns +- 0% -6.28% (p=0.000 n=10+8) BM_CopyNonTrivial/8 21.5ns +- 1% 15.2ns +- 2% -29.23% (p=0.000 n=12+12) ``` Note: the slowdowns are a few cycles which is expected given the procedure call added in that case. We decided this is a good tradeoff given the code size reductions and the more significant speedups for empty vectors. Size difference (as measured by nm): ``` BM_CopyTrivial from 1048 bytes to 326 bytes. BM_CopyNonTrivial from 749 bytes to 470 bytes. ``` Code size for a large binary drops by ~500KB (from 349415719 to 348906015 348906191).

The old pattern of access breaks the `CordRep` type abstraction; since `CordRep::data` is not in general guaranteed to contain the chunk's data, we shouldn't access it that way. This incidentally adds an assertion check (via the flat() accessor) that the CordRep is indeed flat on each such access, but a manual inspection of the code, as well as the fact that this code currently works, suggest that this is always true.)

Keeping the global state as separate global variables results in two issues: 1) False sharing with adjacent global data (e.g., cycle clock source), since the global fields are updated every O(10usec). 2) The hot global fields (e.g., seq and samples) can reside on different cache lines. To fix this, simply wrap the global data in a ABSL_CACHE_ALIGNED structure. This is similar to what we do for MutexGlobals.

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.

PiperOrigin-RevId: 320384329 -- c7b1dacda2739c10dc1ccbfb56b07ed7fe2464a4 by Laramie Leavitt <lar@google.com>: Improve FastUniformBits performance for std::minstd_rand. The rejection algorithm was too pessimistic before, and not in line with the [rand.adapt.ibits]. Specifically, when sampling from an URBG with a non power of 2 range, FastUniformBits constructed a rejection threshold with a power-of-2 range that was too restrictive. For example, minstd_rand has a range of [1, 2147483646], which has a range of 2145386495, or about 30.999 bits. Before FastUniformBits rejected values between 1<<30 and 2145386495, which includes approximately 50% of the generated values. However, since a minimum of 3 calls are required to generate a full 64-bit value from an entropy pool of 30.9 bits, the correct value for rejection sampling is the range value which masks 21 (0x7fe00000) or 22 bits and rejects values greater than that. This reduces the probability of rejecting a sample to about 0.1% NOTE: Abseil random does not guarantee sequence stability over time, and this is expected to change sequences in some cases.

Starting in C++17, when invoke'ing a pointer-to-member, if the object representing the class is a reference_wrapper, that wrapper is unpacked. Because we implement a number of functional APIs that closely match C++ standard proposals, it is better if we follow the standard's notion of what "invoking" means. This also makes `absl::base_internal::Invoke()` match `std::invoke()` in C++17. I intend to make this an alias in a follow-up CL.

In Abseil random, mocking was split across two different classes, MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a test-only library that we don't link into production, so MockingBitGenBase provided a low-overhead scaffold used to lookup mocks when in test code, but which is unused in production code. That has been replaced by type-erasure which looks for a method named CallImpl with the correct signature. Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet. Rename CallImpl to InvokeMock() Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

Stealing string data is faster, but it creates a long chunk, which leads to a higher more memory usage if its subcords are created and outlive the whole Cord. These functions revert to copying the data if any of the following conditions holds: - string size is at most kMaxBytesToCopy (511), to avoid the overhead of an external chunk for short strings; - less than half of string capacity is used, to avoid pinning to much unused memory.

PiperOrigin-RevId: 291982551 -- 47ff4820e595f96c082a90d733725f6882d83e3b by Abseil Team <absl-team@google.com>: Improve ABSL_ATTRIBUTE_PACKED documentation Recommend to apply ABSL_ATTRIBUTE_PACKED to structure members instead of to an entire structure because applying this attribute to an entire structure may cause the compiler to generate suboptimal code. It reduces the alignment of the data structure from a value larger than one to one. When applied to a structure, ABSL_ATTRIBUTE_PACKED reduces the alignment of a structure (alignof()) to 1. As a result, the compiler can no longer assume that e.g. uint32 members are aligned on a four byte boundary and hence is forced to use single-byte load and store instructions on CPU architectures that do not support non-aligned loads or stores.

PiperOrigin-RevId: 291757364 -- 3603adfb59c4128c542b670952cce250d59e1f67 by Derek Mauro <dmauro@google.com>: Separate the initialization of NumCPUs() and NominalCPUFrequency() The OSS version of Abseil never needs to call NominalCPUFrequency(). In some configurations, initializing NominalCPUFrequency() requires spending at least 3ms measuring the CPU frequency. By separating the initialization from NumCPUs(), which is called in most configurations, we can save at least 3ms of program startup time.

This is currently experimental and unsupported. This CL does a few things: 1. Adds the ABSL_DLL macro to any class holding a static data member, or to global constants in headers. 2. Adds a whitelist of all files in the DLL and all the build targets that are conglomerated into the DLL. 3. When BUILD_SHARED_LIBS is specified, any build target that would be in the DLL still exists, but we swap out all of it's dependencies so it just depends on abseil_dll PiperOrigin-RevId: 291192055 -- 5e888cd6f2a7722805d41f872108a03a84e421c7 by Mark Barolak <mbar@google.com>: Move absl/strings/internal/escaping.{cc,h} into internal build targets.
