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.

Version 10.0

* 54fa9ecd3088 - [libc++] Implementation of C++20's P1135R6 for libcxx
libc++ now implements P1135R6 (The C++20 Synchronization Library), which
adds a few symbols to the dylib. This is backwards-compatible since we're
just adding new symbols.

* r358690 - 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.

This bug caused __uncaught_exception to be ODR used instead of

and because users shouldn't be depending directly on libc++ exporting
__uncaught_exception/__uncaught_exceptions.
