-- 5da9755667df37e38ccaf6938c9f408e294110bb by Shaindel Schwartz <shaindel@google.com>: Import of CCTZ from GitHub. PiperOrigin-RevId: 232942734 -- b6fb275769c66fdd2bd92b119198c59e9a7dd737 by Samuel Benzaquen <sbenza@google.com>: Fix integral underflow when from-arg width is INT_MIN. PiperOrigin-RevId: 232888037 -- 4135dbba4a26c4642277fc2a7e2a833d593daa1c by Abseil Team <absl-team@google.com>: Add the insert_return_type alias to raw_hash_set. PiperOrigin-RevId: 232683892 -- 0b120b7d3693800bbb886f6fc607ae54a9338cb1 by Abseil Team <absl-team@google.com>: Macros to detect and disabled SafeStack https://clang.llvm.org/docs/SafeStack.html PiperOrigin-RevId: 232680114 -- a77b3fb533a9e37966d1d6ef5ccd09c73fff2ca1 by Abseil Team <absl-team@google.com>: Avoid potential red zone clobber Pushing on the stack on x86-64 may clobber local variables held below %rsp in the red zone. Avoid this by using lea on x86-64. PiperOrigin-RevId: 232592478 -- bf326a0eefa92f4e704287563df0c5a5b1873b6d by Eric Fiselier <ericwf@google.com>: Add additional tests for AbslHashValue. 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. This patch avoids this warning. PiperOrigin-RevId: 232327626 -- 779c0f44b3c2b7a04d4bdf978641eb8180515bf6 by Eric Fiselier <ericwf@google.com>: Guard against C++2a char8_t change. PiperOrigin-RevId: 232326178 -- 41e5395b85bbbfb5bf418cc21b04ad4ccb15a284 by Eric Fiselier <ericwf@google.com>: Avoid Clang Warning PiperOrigin-RevId: 232138866 GitOrigin-RevId: 5da9755667df37e38ccaf6938c9f408e294110bb Change-Id: I49ee4f58db177b81b039d7d949f671c97c5a7933
