-- 8bdb2020150ed0fd4a4e520e454dc5f54e33f776 by Eric Fiselier <ericwf@google.com>: Workaround bug in GCC 9.2 and after. 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: 291977920 -- 902b7a86f860da699d3a2e5c738be5ef73ede3b4 by Mark Barolak <mbar@google.com>: Internal change PiperOrigin-RevId: 291963048 -- bb3bd3247e376d53a3080b105f13ec7566d3ae50 by Abseil Team <absl-team@google.com>: Support the C++17 insert_or_assign() API in btree_map. PiperOrigin-RevId: 291945474 -- ff3b3cfcbbc64f086f95501f48d49426bcde356f by Gennadiy Rozental <rogeeff@google.com>: Import of CCTZ from GitHub. PiperOrigin-RevId: 291861110 -- fd465cd9cbbacd3962f67a7346d6462edaddd809 by Derek Mauro <dmauro@google.com>: Add flaky=1 to beta_distribution_test. 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. PiperOrigin-RevId: 291737273 -- bea9e4a6bff5a0351d340deab966641867e08c4d by Abseil Team <absl-team@google.com>: Change the cmake library names not to have a redundant `absl_` prefix. PiperOrigin-RevId: 291640501 -- 501b602ef260cd7c8c527342581ceffb3c5b6d4c by Gennadiy Rozental <rogeeff@google.com>: Introducing benchmark for absl::GetFlag. PiperOrigin-RevId: 291433394 -- 4eeaddc788da4b91c272a8adca77ca6dbbbc1d44 by Xiaoyi Zhang <zhangxy@google.com>: fix: Add support for more ARM processors detection Import of https://github.com/abseil/abseil-cpp/pull/608 PiperOrigin-RevId: 291420397 -- a3087a8e883c5d71de7d9bd4ec8f4db5142dfcf5 by Derek Mauro <dmauro@google.com>: Removes the flaky raw_hash_set prefetch test PiperOrigin-RevId: 291197079 -- aad6c2121c102ac36216e771c83227cf3e3bfd66 by Andy Soffer <asoffer@google.com>: Enable building Abseil as a DLL. 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. This puts absl/strings/internal/escaping.h behind a whitelist and it also resolves https://github.com/abseil/abseil-cpp/issues/604. PiperOrigin-RevId: 291173320 -- 166836d24970da87587c1728036f53f05a28f0af by Eric Fiselier <ericwf@google.com>: Internal Change.

PiperOrigin-RevId: 271167776 -- 5f8f1dfea50bc16a9d9af3e50c4636500a938b29 by Abseil Team <absl-team@google.com>: the llvm wasm backend does not support this data symbol in text section, so remove it from the test. PiperOrigin-RevId: 271138100 -- 2874542cb212962ac3093fd78fd5e1eb85c126c0 by Xiaoyi Zhang <zhangxy@google.com>: Work around MSVC 2019 compiler bug related to constexpr in optional_test. The change in optional_test is necessary to avoid another bug on MSVC complaining about accessing invalid member of union, and also makes the test more reasonale by checking the value of a non-static member. Filed a bug against MSVC https://developercommunity.visualstudio.com/content/problem/743998/internal-compiler-error-related-to-constexpr-and-u.html. PiperOrigin-RevId: 271129805 -- 3a5d56f0c3362aabf68938fb95c4e2d3eca59538 by Abseil Team <absl-team@google.com>: Improve precision of absl::GetCurrentTimeNanos() by adjusting cycle time sooner.

This will allow us to delete the GCC 4.8 test since that is currently our only CMake coverage. This also means that we don't have to update the script every time we move to a new minumum GCC version. This change includes a fix for a -Wstringops-truncation warning in symbolize_test.cc that triggers when it is built in release mode with the latest GCC.

PiperOrigin-RevId: 232344325 -- 816e4f98fd7632c944c779db87b7dac4e138afcf by Eric Fiselier <ericwf@google.com>: Avoid upcoming GCC 9.0 warnings about base class init. Currently, in trunk, GCC has a new warning under -Wextra that diagnoses when a derived class fails to explicitly initialize the base class in a constructor initializer list.
