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 8.0

|
-----------
|
|
|
|
* r345260 - Making libc++ build under -fvisibility=hidden
|
|
|
|
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.

|
* r333467 - Fix embarrasing typo in uncaught_exceptions.
|
|
|
|
This bug caused __uncaught_exception to be ODR used instead of
|
|
__uncaught_exceptions. This change is non-ABI breaking because the symbols
|
|
for std::uncaught_exception and std::uncaught_exceptions haven't changed,
|
|
and because users shouldn't be depending directly on libc++ exporting
|
|
__uncaught_exception/__uncaught_exceptions.

|
* r296729 - Remove std::num_get template methods which should be inline
|
|
|
|
These functions should never have had visible definitions in the dylib but
|
|
since they were previously not specified with 'inline' they accidentally
|
|
got emitted. This change is non-ABI breaking because every "linkage unit"
|
|
must contain its own definition.

These functions should never have had visible definitions in the dylib but

since they were previously not specified with 'inline' they accidentally

got emitted. This change is non-ABI breaking because every "linkage unit"

* r285101 - Add -fvisibility-inlines-hidden when building libc++.
|
|
|
|
Although this change removes symbols, it should still be non-ABI breaking
|
|
since all of the definitions removed are inline functions. For this reason
|
|
removing these symbols is safe because every "linkage unit" which uses these
|
|
functions will contain their own definition.
