-- 1c1d6e2404dfc6caa022b335df5acdac6da50fe1 by Derek Mauro <dmauro@google.com>: Fix the internal namespacing in unaligned_access.h PiperOrigin-RevId: 215434506 -- 17d4400aebf025a230690fc1c7a968ef8d85bbba by Eric Fiselier <ericwf@google.com>: gtest depends on the GCC extension allowing variadic macros to be passed a empty parameter pack for ..., but LLVM diagnoses this as a GNU extension. This patch suppresses the warning when building the absl tests. PiperOrigin-RevId: 215426161 -- f2c49dde23a9f445b9de963f1bbe840ebb568b30 by Eric Fiselier <ericwf@google.com>: Use EXPECT_DEATH_IF_SUPPORTED instead of EXPECT_DEATH. This avoids breaking the test when gtest doesn't support death tests. PiperOrigin-RevId: 215423849 -- cd687c1e121709603f4fc3726b534f6a9c52cc89 by Eric Fiselier <ericwf@google.com>: Disable LLVM's -Wmissing-variable-declarations in tests. GCC's configuration already disables this via -Wno-missing-declarations, this change makes LLVM do the same. The warning would otherwise flag most tests which use ABSL_FLAG. PiperOrigin-RevId: 215407429 -- d14098824c84e3a8c8f6fb920e0335fb48fe2010 by Eric Fiselier <ericwf@google.com>: Fix local variable shadowing in city hash implementation. PiperOrigin-RevId: 215407249 -- 4b5e140ba743f0d231790a26c49083abb4329e2c by Abseil Team <absl-team@google.com>: Make raw_hash_set::reserve 2X fast when reserve doesn't do any allocation. Make raw_hash_set::reserve ~1% faster when reserve does some (128~4k) allocation. PiperOrigin-RevId: 215348727 -- 461161e65e04b801480aa117af2534c594654ccf by Eric Fiselier <ericwf@google.com>: Internal change PiperOrigin-RevId: 215272283 -- 50413ae31ad3d3a177257416acd8ede47a17bff2 by Eric Fiselier <ericwf@google.com>: Internal Change PiperOrigin-RevId: 215233183 -- 477be54c43d61019a8fe4e190e340eb52737d383 by Abseil Team <absl-team@google.com>: Clarify misleading comment on ABSL_ATTRIBUTE_UNUSED PiperOrigin-RevId: 215185496 -- 2cafa2b5287507d3a946682aee9ab13af6d471c9 by Matt Kulukundis <kfm@google.com>: Add support for absl::Hash to various absl in types. PiperOrigin-RevId: 215039569 -- 082248901991aa3d29be0ea3689c7f213cf0fd83 by Derek Mauro <dmauro@google.com>: Remove an instance of HAS_GLOBAL_STRING from hash_function_defaults.h PiperOrigin-RevId: 214989094 -- b929f61907f0786a6133e3a9d7287e339c0a0acb by Derek Mauro <dmauro@google.com>: Internal import of Github #174 Fix code snippet in comment https://github.com/abseil/abseil-cpp/pull/174 PiperOrigin-RevId: 214958849 -- f2c5e829eca11c352e121f56eefbf87083305023 by Derek Mauro <dmauro@google.com>: Internal import of GitHub #173 Fix CMake build for absl::container. https://github.com/abseil/abseil-cpp/pull/173 PiperOrigin-RevId: 214957796 -- d704f860f9fddafb99e34e6c5032e49f73874e10 by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 214828181 GitOrigin-RevId: 1c1d6e2404dfc6caa022b335df5acdac6da50fe1 Change-Id: I551de2b1ba0cbaf6856cd5959358cf6651179dea
