// 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.
