From f21d187b80e3b7f08fb279775ea9c8b48c636030 Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Tue, 2 Oct 2018 12:09:18 -0700 Subject: Export of internal Abseil changes. -- 1c1d6e2404dfc6caa022b335df5acdac6da50fe1 by Derek Mauro : Fix the internal namespacing in unaligned_access.h PiperOrigin-RevId: 215434506 -- 17d4400aebf025a230690fc1c7a968ef8d85bbba by Eric Fiselier : 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 : 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 : 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 : Fix local variable shadowing in city hash implementation. PiperOrigin-RevId: 215407249 -- 4b5e140ba743f0d231790a26c49083abb4329e2c by Abseil Team : 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: 215039569 -- 082248901991aa3d29be0ea3689c7f213cf0fd83 by Derek Mauro : Remove an instance of HAS_GLOBAL_STRING from hash_function_defaults.h PiperOrigin-RevId: 214989094 -- b929f61907f0786a6133e3a9d7287e339c0a0acb by Derek Mauro : 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 : 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 : Internal change PiperOrigin-RevId: 214828181 GitOrigin-RevId: 1c1d6e2404dfc6caa022b335df5acdac6da50fe1 Change-Id: I551de2b1ba0cbaf6856cd5959358cf6651179dea --- absl/types/BUILD.bazel | 2 ++ absl/types/span.h | 7 +++++++ absl/types/span_test.cc | 1 + 3 files changed, 10 insertions(+) (limited to 'absl/types') diff --git a/absl/types/BUILD.bazel b/absl/types/BUILD.bazel index 7841a97..32f690c 100644 --- a/absl/types/BUILD.bazel +++ b/absl/types/BUILD.bazel @@ -136,6 +136,7 @@ cc_test( "//absl/base:exception_testing", "//absl/container:fixed_array", "//absl/container:inlined_vector", + "//absl/hash:hash_testing", "//absl/strings", "@com_google_googletest//:gtest_main", ], @@ -153,6 +154,7 @@ cc_test( "//absl/base:exception_testing", "//absl/container:fixed_array", "//absl/container:inlined_vector", + "//absl/hash:hash_testing", "//absl/strings", "@com_google_googletest//:gtest_main", ], diff --git a/absl/types/span.h b/absl/types/span.h index 3359ce5..911af0c 100644 --- a/absl/types/span.h +++ b/absl/types/span.h @@ -485,6 +485,13 @@ class Span { : (base_internal::ThrowStdOutOfRange("pos > size()"), Span()); } + // Support for absl::Hash. + template + friend H AbslHashValue(H h, Span v) { + return H::combine(H::combine_contiguous(std::move(h), v.data(), v.size()), + v.size()); + } + private: pointer ptr_; size_type len_; diff --git a/absl/types/span_test.cc b/absl/types/span_test.cc index fbce7e8..bd739ff 100644 --- a/absl/types/span_test.cc +++ b/absl/types/span_test.cc @@ -29,6 +29,7 @@ #include "absl/base/internal/exception_testing.h" #include "absl/container/fixed_array.h" #include "absl/container/inlined_vector.h" +#include "absl/hash/hash_testing.h" #include "absl/strings/str_cat.h" namespace { -- cgit v1.2.3
