-- 5a5dba4252e764e6737070bf0a31074bf23a3b41 by Abseil Team <absl-team@google.com>: Internal change. PiperOrigin-RevId: 244898913 -- 3eb7d5b445ffbf08a104e39cd15aecf568417333 by Matt Calabrese <calabrese@google.com>: Introduce absl::is_trivially_move_constructible and absl::is_trivially_move_assignable, and update the absl::is_trivially_copy_constructible and absl::is_trivially_copy_assignable traits to use similar techniques (should now be closer to the standard behavior). PiperOrigin-RevId: 244859015 -- 7da05a24fa786cab3985de0c39a186d73dcbcfb5 by Abseil Team <absl-team@google.com>: Fix misspellings in comments in raw_hash_set.h. PiperOrigin-RevId: 244754700 -- 5c057be96048f21473d5ec45005ab4dcd8dd354f by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 244744239 -- 592394e3c2e98f1238d3fb6fcb0d20c3e3739ba9 by Derek Mauro <dmauro@google.com>: Limit the raw_hash_set prefetch test to x86-64. PiperOrigin-RevId: 244737534 -- 99ebe4e003633c8ff7838b035b31a827994879ef by Derek Mauro <dmauro@google.com>: Workaround warning 4091 in an MSVC header. PiperOrigin-RevId: 244701744 -- 0aa23f09a32efe7985ee55b0217190f08da42477 by Abseil Team <absl-team@google.com>: Fix comment typo. PiperOrigin-RevId: 244659371 -- c6cdb87e9f28062c8daa29b3d8d68182ecc16383 by Derek Mauro <dmauro@google.com>: Fix -Wundef warnings and support -Wundef. PiperOrigin-RevId: 244244968 -- 06b81245f7696b20c3c63b0618d33ac25e29cad6 by Abseil Team <absl-team@google.com>: Fix a typo in inlined_vector.h. PiperOrigin-RevId: 244230809 -- 94877a2125d2cfe837384240e4d6551f39d737e4 by Greg Falcon <gfalcon@google.com>: Fix sysinfo_test for emscripten. PiperOrigin-RevId: 244198804 -- ec7783531ef7f9df2da37d341d61f7cb2bf843f0 by Shaindel Schwartz <shaindel@google.com>: Import of CCTZ from GitHub. Fixes #291. PiperOrigin-RevId: 244184598 -- b652c14fa95ea206c217487ee713b11f5d1762b3 by Matt Calabrese <calabrese@google.com>: Emulate the `in_place_index` and `in_place_type` variable templates such that they are syntactically usable in C++11 with `any` and `variant`. Also pull in the variable templates from namespace std when available. The main observable differences here are: 1) The types of `in_place_index_t<I>` and `in_place_type_t<T>` become function pointer types rather than structs when using the implementation that is not an alias of the std equivalents. 2) The types of `in_place_index<I>` and `in_place_type<T>` are not directly `in_place_index_t<I>` and `in_place_type_t<T>`, but rather they become function types that decay to the corresponding function pointer types. 3) The default constructor for `in_place_index_t` and `in_place_type_t` instantiations is no longer explicit, but for these templates I think that's less important than for something like `in_place_t` since the _type_t and _index_t versions basically never have their template parameter non-deduced when participating in overload resolution with conflicting candidates. 4) While idiomatic usage of `in_place_type_t` and `in_place_index_t` with std::variant and std::any should not be affected, there is the possibility that strange, non-idiomatic uses may be affected in the wild. 5) Default construction (rather than value-initialization) leads to a default-constructed pointer. PiperOrigin-RevId: 244180003 -- b9ac5a96581837ffa24532117b7ea302a5569751 by Derek Mauro <dmauro@google.com>: Fix MSVC debug assertion. isprint is undefined for values not representable as unsigned char or EOF. PiperOrigin-RevId: 244083005 -- 41758be6137c2f25e84b50f23938e49484be2903 by Shaindel Schwartz <shaindel@google.com>: Update config settings for Apple platforms. PiperOrigin-RevId: 244040587 -- c90df6a26db94b0305a0c954455a621542a89d91 by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 244024427 -- c71e9ceb89495354eca7d02bd905ffeaa9029aec by Derek Mauro <dmauro@google.com>: Adds missing ABSL_DEFAULT_COPTS and ABSL_TEST_COPTS to CMakeLists.txt Don't error on deprecated declarations in tests. It is completely reasonable to test that code marked deprecated still works. PiperOrigin-RevId: 244003941 -- e1326a96527a8ba9b8d120161545260da9c4562e by Abseil Team <absl-team@google.com>: Internal change.

PiperOrigin-RevId: 243894308 -- 317fef3344481ebc5c35712d42f5d8a0fa64dff4 by Abseil Team <absl-team@google.com>: Enable raw logging in Emscripten builds.
