| 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. |

| * r288547 - Implement C++17 <variant> |
| |
| All Platforms |

| Symbol added: _ZTVSt18bad_variant_access |
| Symbol added: _ZTISt18bad_variant_access |
| Symbol added: _ZTSSt18bad_variant_access |
| Symbol added: _ZNKSt18bad_variant_access4whatEv |
| |
| * rTBD - 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. |
