| // 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. |
