1 ABI Changelog 2 ============== 3 This changelog contains information about ABI changes in libc++. Specifically 4 the addition and deletion of symbols from the libc++ dylib. 5 6 Each entry should start with the revision number followed by a description of 7 the change. The entry should contain a summary of the ABI changes made, 8 including what symbols were added, removed, or changed. 9 10 To generate a summary use "sym_diff.py" diffing against the appropriate ABI list. 11 Afterwards the ABI list should be updated to include the new changes. 12 13 New entries should be added directly below the "Version" header. 14 15 ----------- 16 Version 5.0 17 ----------- 18 19 * r313500 - Fix undefined "___cxa_deleted_virtual" symbol in macosx 20 21 x86_64-linux-gnu 22 ---------------- 23 No changes 24 25 x86_64-apple-darwin16.0 26 ----------------------- 27 Symbol added: ___cxa_deleted_virtual 28 29 * r296729 - Remove std::num_get template methods which should be inline 30 31 These functions should never have had visible definitions in the dylib but 32 since they were previously not specified with 'inline' they accidentally 33 got emitted. This change is non-ABI breaking because every "linkage unit" 34 must contain its own definition. 35 36 x86_64-linux-gnu 37 ---------------- 38 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE15__do_get_signedIlEES4_S4_S4_RNS_8ios_baseERjRT_ 39 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE15__do_get_signedIxEES4_S4_S4_RNS_8ios_baseERjRT_ 40 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE17__do_get_unsignedIjEES4_S4_S4_RNS_8ios_baseERjRT_ 41 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE17__do_get_unsignedImEES4_S4_S4_RNS_8ios_baseERjRT_ 42 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE17__do_get_unsignedItEES4_S4_S4_RNS_8ios_baseERjRT_ 43 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE17__do_get_unsignedIyEES4_S4_S4_RNS_8ios_baseERjRT_ 44 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE23__do_get_floating_pointIdEES4_S4_S4_RNS_8ios_baseERjRT_ 45 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE23__do_get_floating_pointIeEES4_S4_S4_RNS_8ios_baseERjRT_ 46 SYMBOL REMOVED: _ZNKSt3__17num_getIcNS_19istreambuf_iteratorIcNS_11char_traitsIcEEEEE23__do_get_floating_pointIfEES4_S4_S4_RNS_8ios_baseERjRT_ 47 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE15__do_get_signedIlEES4_S4_S4_RNS_8ios_baseERjRT_ 48 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE15__do_get_signedIxEES4_S4_S4_RNS_8ios_baseERjRT_ 49 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE17__do_get_unsignedIjEES4_S4_S4_RNS_8ios_baseERjRT_ 50 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE17__do_get_unsignedImEES4_S4_S4_RNS_8ios_baseERjRT_ 51 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE17__do_get_unsignedItEES4_S4_S4_RNS_8ios_baseERjRT_ 52 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE17__do_get_unsignedIyEES4_S4_S4_RNS_8ios_baseERjRT_ 53 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE23__do_get_floating_pointIdEES4_S4_S4_RNS_8ios_baseERjRT_ 54 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE23__do_get_floating_pointIeEES4_S4_S4_RNS_8ios_baseERjRT_ 55 SYMBOL REMOVED: _ZNKSt3__17num_getIwNS_19istreambuf_iteratorIwNS_11char_traitsIwEEEEE23__do_get_floating_pointIfEES4_S4_S4_RNS_8ios_baseERjRT_ 56 57 x86_64-apple-darwin16.0 58 ----------------------- 59 No changes 60 61 ----------- 62 Version 4.0 63 ----------- 64 65 * r290651 - Add _LIBCPP_ASSERT debug handling functions 66 67 All Platforms 68 ------------- 69 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC2ERKNS_19__libcpp_debug_infoE 70 Symbol added: _ZNSt3__124__libcpp_debug_exceptionD1Ev 71 Symbol added: _ZTINSt3__124__libcpp_debug_exceptionE 72 Symbol added: _ZNSt3__129__libcpp_throw_debug_functionERKNS_19__libcpp_debug_infoE 73 Symbol added: _ZNSt3__124__libcpp_debug_exceptionD2Ev 74 Symbol added: _ZNSt3__129__libcpp_abort_debug_functionERKNS_19__libcpp_debug_infoE 75 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC2ERKS0_ 76 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC1Ev 77 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC1ERKNS_19__libcpp_debug_infoE 78 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC2Ev 79 Symbol added: _ZTSNSt3__124__libcpp_debug_exceptionE 80 Symbol added: _ZNSt3__123__libcpp_debug_functionE 81 Symbol added: _ZNKSt3__124__libcpp_debug_exception4whatEv 82 Symbol added: _ZNSt3__124__libcpp_debug_exceptionC1ERKS0_ 83 Symbol added: _ZNSt3__124__libcpp_debug_exceptionD0Ev 84 Symbol added: _ZTVNSt3__124__libcpp_debug_exceptionE 85 Symbol added: _ZNSt3__127__libcpp_set_debug_functionEPFvRKNS_19__libcpp_debug_infoEE 86 87 * r288547 - Implement C++17 <variant> 88 89 All Platforms 90 ------------- 91 Symbol added: _ZTVSt18bad_variant_access 92 Symbol added: _ZTISt18bad_variant_access 93 Symbol added: _ZTSSt18bad_variant_access 94 Symbol added: _ZNKSt18bad_variant_access4whatEv 95 96 * r285537 - Remove std::string::append template methods which should be inline 97 98 These functions should never have had visible definitions in the dylib but 99 since they were previously not specified with 'inline' they accidentally 100 got emitted.
