From c5c4db4f5191fe5e76cbf68dcc71fb28702f7d2b Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Mon, 5 Aug 2019 11:32:04 -0700 Subject: Export of internal Abseil changes -- f8fe0f483378c7520d8f8bdfabe4b20de4d96c7e by Andy Soffer : Ensure that Invoke can support C++17 in the sense that noexcept is part of the type. PiperOrigin-RevId: 261730155 -- bf796ab71653a80498f9374bc8c5111d065c64ba by Abseil Team : Fix typo in static_assert message for copy/move constructible by replacing "by" with "be". PiperOrigin-RevId: 261713992 -- 8c7c17c40d03a322f304a2fd73ed34462dbf265a by Andy Soffer : Add absl::is_function drop-in replacement for std::is_function. Some standard libraries incorrectly implement std::is_function in a few corner cases. In particular, libstdc++ functions marked noexcept. The trick being used here is that function types decay to pointers. After excluding cases like is_class, etc, we can distinguish function types by testing for this decay. Many thanks to ericwf@ for essentially writing this CL. PiperOrigin-RevId: 261705008 -- c5adf42d0a132c2525d17a719329eab2ffe0aa94 by Abseil Team : Add microbenchmark for StrSplit that uses delimiter ByAnyChar. PiperOrigin-RevId: 261424010 -- 66a342f9381ec56be2fe3aa5b3193dd3538a9740 by Andy Soffer : CMake support for Abseil Random This change touches almost build-related files for CMake almost exclusively. The one minor exception is random/internal/salted_seed_seq.h. The default warnings configuration for one of our CI builds requests not having named but unused parameters. The change in this file cleans up that warning.
