| 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, re-generate the new ABI list using the |
| `generate-cxx-abilist` target, and look at the diff. |
| |
| New entries should be added directly below the "Version" header. |

| * [libc++abi] Implement __cxa_init_primary_exception and use it to optimize std::make_exception_ptr (#65534) |
| |
| This patch implements __cxa_init_primary_exception, an extension to the Itanium C++ ABI. |
| This extension is already present in both libsupc++ and libcxxrt. This patch also starts |
| making use of this function in std::make_exception_ptr: instead of going through a full |
| throw/catch cycle, we are now able to initialize an exception directly, thus making |
| std::make_exception_ptr around 30x faster. Adding a new symbol is not an ABI break. |

| Symbol added: __cxa_init_primary_exception |
| |
| * [libc++] Simplify the implementation of locale::id |
| |
| This patch removes a symbol defined in the library for std::locale::id::__init(). |
| The symbol '__init' was defined as a private static function as part of the locale::id |
| class and was never visible from outside the dylib. The addition of this symbol to the |
| ABI was most likely accidental. The deletion of the symbol should not be a breaking change. |

| |
| * [libc++] Remove symbol for std::system_error from the dylib |
| |
| This patch removes a symbol defined in the library for std::system_error. |
| The symbol '__init' was defined as a private static function as part of the |
| system_error class and was never visible. The addition of this symbol to the ABI was most likely accidental. |
| The function '__init' is replaced by another equivalent function which is placed in the |
| anonymous namespace of the std::system_error source code file. |
| There are no internal references to this symbol which seems to support the reasoning that |
| this was never used outside of the dylib. |
| The deletion of the symbol should not be a breaking change. |

| |
| * [libc++] Remove symbols for a std::allocator_arg & friends from the dylib |
| |
| This patch removes the symbols defined in the library for std::allocator_arg, |
| std::defer_lock, std::try_to_lock, std::adopt_lock, and std::piecewise_construct. |
| Those were defined in the library because we provided them in C++03 as an |
| extension, and in C++03 it was impossible to define them as `constexpr` |
| variables, as required by the Standard. |
| |
| This is technically an ABI break since we are removing symbols from the |
| library. However, in practice, only programs compiled in C++03 mode that |
| take the address of those objects (or pass them as a reference) will have |
| an undefined ref to those symbols. In practice, this is expected to be |
| rare. First, those are C++11 features that we happen to provide in C++03, |
| and only the C++03 definition can potentially lead to code referencing |
| the dylib definition. So any code that is using these objects but compiling |
| in C++11 mode (as they should) is not at risk. Second, all uses of these |
| types in the library is done by passing those types by value to a function |
| that can get inlined. Since they are empty types, the compiler won't |
| generate an undefined reference if passed by value, since there's nothing |
| to pass anyway. |
| |
| Long story short, the risk for code actually containing an undefined |
| reference to one of these types is rather small (but non-zero). |

| * f1c30135417f - [libc++] Drop the legacy debug mode symbols by default |
| |
| This commit removed symbols implementing debug mode in the non-debug |
| configuration of the library. Using the debug mode now requires a |
| differently-configured version of libc++. This is technically an ABI |
| break, however any user having been using the debug mode support previously |
| was already at risk of non-benign ODR violations, and in practice we |
| never found it to work reliably. |

| * 434dc0a5bcae - [libc++] Always define a key function for std::bad_function_call in the dylib |
| |
| This commit added a new explicit instantiation of std::bad_function_call's |
| vtable in the shared library. This change is not an ABI break as it only |
| adds symbols to the library. Programs compiled against the library will not |
| rely on the vtable being defined in it by default. Reliance on the vtable |
| being in the shared library can be enabled by defining the |
| _LIBCPP_ABI_BAD_FUNCTION_CALL_KEY_FUNCTION macro. |
| |
| Note that this commit also causes the libc++ shared library to start relying |
| on std::exception::what() being provided. This is due to the fact that the |
| shared library now contains the vtable for std::bad_function_call, which |
| references std::exception::what(). This shouldn't be an issue since that |
| function needs to be available to users in order to use std::bad_function_call |
| before this patch too. |

| * 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. |

| * 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. |

| for std::uncaught_exception and std::uncaught_exceptions haven't changed, |
