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 7.0
|
|
-----------
|
|
|
|
* 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.
|
|
|
|
All Platforms
|
|
----------------

SYMBOL REMOVED: __cxa_uncaught_exception

Symbol added: ___cxa_deleted_virtual
|
|
|
|
* 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.

* r285537 - Remove std::string::append 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.

* 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.
