-- eca34da4ccb7bb6a580f1364dff9ca053418fa3b by Abseil Team <absl-team@google.com>: Internal change. PiperOrigin-RevId: 214305433 -- 35393bdd21a87c4286f945fd34dda93afc4e0cd6 by Abseil Team <absl-team@google.com>: Move some implementation details of string_view around to facilitate compiling on NVCC. Abseil does not officially support NVCC as a reminder. PiperOrigin-RevId: 214184876 -- 61846cab9ab9476a4676ecade7173f68978cd038 by Jorg Brown <jorg@google.com>: Move the initialization values for constants back to their declaration. PiperOrigin-RevId: 214135927 -- 7ac7df6c5f78f2faf419268c04618b936cb26065 by Abseil Team <absl-team@google.com>: Performance improvements on format parser. PiperOrigin-RevId: 214032366 -- 90b4c0cf20e9feaa257a7ece40adaf7db40a60a7 by Xiaoyi Zhang <zhangxy@google.com>: Add static_assert check to absl::visit to make sure all overloads of the visitor return the same type, as required by the C++ standard. PiperOrigin-RevId: 213677001 -- 787995342101b4c181291cde9ecea3048536e4bd by Abseil Team <absl-team@google.com>: Update comment to indicate finite durations are less than InfiniteDuration. PiperOrigin-RevId: 213660328 -- d78f0dce7cc31218807e96d93b9e8513b6c80b24 by Jon Cohen <cohenjon@google.com>: s/invariant/contract in the exceptions safety testing framework. This is a better term as these can be type invariants or function post conditions. They also are very similar ground as to what is covered by c++20 Contracts (and could even be replaced by them. PiperOrigin-RevId: 213631019 -- 0b3ff1a640de9a7391a6c233568802cf86245b0e by Abseil Team <absl-team@google.com>: Add noinline attribute for GetStackTrace/GetStackFrames/... so the skipped frames will not change because of inlining difference. PiperOrigin-RevId: 213009637 GitOrigin-RevId: eca34da4ccb7bb6a580f1364dff9ca053418fa3b Change-Id: Iff1022fd24e440fcbdf3c4ab2a915ca8954daa31
