* Avoid a empty library build failure on Apple platformsDerek Mauro2024-01-033-0/+54
| | | | | | | | | | | | | | | | | | | | | https://github.com/abseil/abseil-cpp/issues/1465 reports that some CMake builds on Apply platforms issue ``` warning: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive library: libabsl_bad_any_cast_impl.a the table of contents is empty (no object file members in the library define global symbols) ``` Our CMake build handles this problem for header-only libraries by not building a library at all. For some libraries, for example our polyfills, the library is only conditionally empty. In these libraries, I added a single char variable on Apple platforms as a workaround. I have been able to reproduce the warnings reported in https://github.com/abseil/abseil-cpp/issues/1465, but they don't fail the build for me. I don't see them any more after this change.

| | | | | | | | * Also does this for `absl::internal::identity_t` which is now `absl::internal::type_identity_t` * This is clearer naming as this is a backfill of `std::type_identity` (the identity type), and not `std::identity` (the identity function) PiperOrigin-RevId: 594316002 Change-Id: I5fb8cf7e3d07c1bc736cbecd202e7d556b6ea33e
* Remove nullability from Span::{pointer,iterator}Sam McCall2023-12-151-2/+4
| | | | | | | | | | | | These are in some sense correct (begin()/end() can be null for empty spans), but don't capture the critical contract that begin() is only null when end() is. This leads to foreach loops over spans being considered unsafe. Long-term we may want to express such constraints somehow, but for now giving these pointers unknown nullability is the best we can do.

| | | | | | | | | | | | types when they are available. This makes them interchangeable in contexts known to be compiled as C++20. This also makes `absl::` ordering types compatible with `<=>`, allowing to unconditionally use `absl::` spelling for types but conditionally use `<=>` when available.

* Remove `absl::weak_equality` and `absl::strong_equality`.Marcin Kowalczyk2023-12-042-221/+4
| | | | | | | | | | | | | | | | | | | | The corresponding `std` types were removed before C++20 was finalized: https://wg21.link/P1959R0. They are unused. The language mechanisms and recommendations changed since they were originally proposed. In particular: * An explicitly defaulted `operator==` is defined in terms of memberwise `operator==` rather than sibling `operator<=>`. * An `operator!=` can be implicitly added to an overload set in terms of `operator==` rather than `operator<=>`. * A class which has equality but not ordering defined should provide `operator==` rather than `operator<=>`.

* Bazel: Support layering_check and parse_headersDerek Mauro2023-10-101-1/+16
| | | | | | | | | | | | | The layering_check feature ensures that rules that include a header explicitly depend on a rule that exports that header. Compiler support is required, and currently only Clang 16+ supports diagnoses layering_check failures. The parse_headers feature ensures headers are self-contained by compiling them with -fsyntax-only on supported compilers.

There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks. Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

* Fix C++17 constexpr storage deprecation warningsDerek Mauro2022-06-091-0/+2
| | | | | | | | | | | | | | | | | | | This change introduces the symbol ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL to guard redundant declarations of static constexpr data members that are needed prior to C++17. This change also introduces the symbol ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set to the same value as __cplusplus, except it uses _MSVC_LANG on MSVC so that the value is correct on MSVC. Neither of these new symbols should be used outside of Abseil. Fixes #1191 PiperOrigin-RevId: 453923908 Change-Id: I1316c52c19fa0c168b93cced0c817e4cb7c9c862
