| ABI Changelog |
| ============== |
| This changelog contains information about ABI changes in libc++. Specifically |
| the addition and deletion of symbols from the libc++ dylib. |
| |
| Each entry should start with the revision number followed by a description of |
| the change. The entry should contain a summary of the ABI changes made, |
| including what symbols were added, removed, or changed. |
| |
| To generate a summary use "sym_diff.py" diffing against the appropriate ABI list. |
| Afterwards the ABI list should be updated to include the new changes. |
| |
| New entries should be added directly below the "Version" header. |
| |

| * rXXXXX - Re-rexport missing symbols from libc++abi |
| |
| libc++ now re-exports `__cxa_throw_bad_array_new_length` and `__cxa_uncaught_exceptions`, |
| both of which are provided by libc++abi. This is not an ABI break because |
| we're just adding symbols. Also, this does mean that libc++ can't be linked |
| against an older version of libc++abi that doesn't provide those symbols, |
| however doing so is not supported anyway. |

| * r356518 - Integrate <filesystem> support into the shared library |
| |
| This patch introduces support for <filesystem> into the shared library, |
| instead of requiring users to manually link against a static archive. As |
| such, new symbols required to implement <filesystem> are exported from |
| the shared library. |

| * r356417 - Remove exception throwing debug mode handler support. |
| |
| The reason libc++ implemented a throwing debug mode handler was for ease of testing. Specifically, |
| I thought that if a debug violation aborted, we could only test one violation per file. This made |
| it impossible to test debug mode. Which throwing behavior we could test more! |
| |
| However, the throwing approach didn't work either, since there are debug violations underneath noexcept |
| functions. This lead to the introduction of `_NOEXCEPT_DEBUG`, which was only noexcept when debug |
| mode was off. |
| |
| Having thought more and having grown wiser, `_NOEXCEPT_DEBUG` was a horrible decision. It was |
| viral, it didn't cover all the cases it needed to, and it was observable to the user -- at worst |
| changing the behavior of their program. |
| |
| This patch removes the throwing debug handler, and rewrites the debug tests using 'fork-ing' style |
| death tests. |

| * r355367 - Fix -fsanitize=vptr badness in <__debug> |
| |
| This patch fixes a lifetime bug when inserting a new container into the debug database. It is |
| diagnosed by UBSAN when debug mode is enabled. This patch corrects how nodes are constructed |
| during insertion. |
| |
| The fix requires unconditionally breaking the debug mode ABI. Users should not expect ABI |
| stability from debug mode. |

| * r347903 - Remove std::bad_array_length |
| |
| The change removes the definition of std::bad_array_length (which never made |
| it into the standard) from the headers and the dylib. This is technically an |
| ABI break because the symbols are shipped starting with mac OSX 10.13, however |
| users couldn't be relying on the functionality because it is marked as being |
| unavailable using Clang's availability attribute. |

| * r347395 - Making libc++ build under -fvisibility=hidden on Linux |
| |
| The change marks several function templates as hidden. This removes symbols |
| from the shared library, but this is not an ABI break because it's impossible |
| for programs linking against libc++.so to actually depend on that symbol. |
| The reason is that the symbol is exported from the shared library through |
| an implicit instantiation present in the shared object itself only. Furthermore, |
| if a user's shared object was implicitly instantiating one of these functions, |
| marking that symbol as hidden would not be an ABI break for them because none |
| of their users could actually be using the symbol in their dylib (because |
| it's an implicit instantiation). |

| * r345260 - Making libc++ build under -fvisibility=hidden on Mac OS |
| |
| The change marks __thread_specific_ptr<__thread_struct>::__at_thread_exit(void*) |
| with hidden visibility. This removes a symbol from the shared libraries, |
| however this is not an ABI break because it's impossible for programs linking |
| against libc++.dylib to actually depend on that symbol. The reason is that |
| the symbol is exported from the shared library through an implicit |
| instantiation present in the dylib itself only. Furthermore, if a user's |
| dylib was implicitly instantiating __thread_specific_ptr<T>::__at_thread_exit |
| (because it's defined in the headers), marking that symbol as hidden would |
| not be an ABI break for them because none of their users could actually be |
| using the symbol in their dylib (because it's an implicit instantiation). |
| |
| This change also marks __start_std_streams as hidden -- this variable is |
| only required to initialize the streams, and nobody should depend on it |
| from outside the dylib. |
