#ifndef _LIBCPP_CONFIG_SITE #define _LIBCPP_CONFIG_SITE // Dynamic libc++ configuration macros are in // build/config/libc++:runtime_library. This file only has defines // that are constant across platforms, or easily set via preprocessor checks. // Things that are set depending on GN args are not here. // We set a custom _LIBCPP_ABI_NAMESPACE for the following reasons: // // 1. When libcxx_is_shared is true, symbols from libc++.so are exported for all // DSOs to use. If the system libc++ gets loaded (indirectly through a // a system library), then it will conflict with our libc++.so. // 2. The default value of _LIBCPP_ABI_NAMESPACE is the string // "_LIBCPP_ABI_NAMESPACE". This contributes to an increase in binary size; // on Windows, the increase is great enough that we go above the 4GB size // limit for PDBs (https://crbug.com/1327710#c5). To fix this, we set // _LIBCPP_ABI_NAMESPACE to a shorter value. #define _LIBCPP_ABI_NAMESPACE __Cr #define _LIBCPP_ABI_VERSION 2 #define _LIBCPP_ABI_FORCE_ITANIUM 0 #define _LIBCPP_ABI_FORCE_MICROSOFT 0 #define _LIBCPP_HAS_THREADS 1 #define _LIBCPP_HAS_MONOTONIC_CLOCK 1 #define _LIBCPP_HAS_TERMINAL 1 #define _LIBCPP_HAS_MUSL_LIBC 0 #ifdef _WIN32 #define _LIBCPP_HAS_THREAD_API_PTHREAD 0 #define _LIBCPP_HAS_THREAD_API_EXTERNAL 0 #define _LIBCPP_HAS_THREAD_API_WIN32 1 #else #define _LIBCPP_HAS_THREAD_API_PTHREAD 1 #define _LIBCPP_HAS_THREAD_API_EXTERNAL 0 #define _LIBCPP_HAS_THREAD_API_WIN32 0 #endif /* #undef _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS */ #define _LIBCPP_HAS_VENDOR_AVAILABILITY_ANNOTATIONS 0 /* #undef _LIBCPP_NO_VCRUNTIME */ /* #undef _LIBCPP_TYPEINFO_COMPARISON_IMPLEMENTATION */ #define _LIBCPP_HAS_FILESYSTEM 1 #define _LIBCPP_HAS_RANDOM_DEVICE 1 #define _LIBCPP_HAS_LOCALIZATION 1 #define _LIBCPP_HAS_UNICODE 1 #define _LIBCPP_HAS_WIDE_CHARACTERS 1 // TODO(thakis): Is this right? /* #undef _LIBCPP_HAS_NO_STD_MODULES */ // TODO(thakis): Is this right? #define _LIBCPP_HAS_TIME_ZONE_DATABASE 1 // _LIBCPP_INSTRUMENTED_WITH_ASAN is set in build/config/c++/BUILD.gn. // PSTL backends /* #undef _LIBCPP_PSTL_BACKEND_SERIAL */ #if defined(__APPLE__) #define _LIBCPP_PSTL_BACKEND_LIBDISPATCH #else #define _LIBCPP_PSTL_BACKEND_STD_THREAD #endif // Settings below aren't part of __config_site upstream. // We set them here since we want them to take effect everywhere, // unconditionally. // Prevent libc++ from embedding linker flags to try to automatically link // against its runtime library.
