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, re-generate the new ABI list using the 11 `generate-cxx-abilist` target, and look at the diff. 12 13 New entries should be added directly below the "Version" header. 14 15 ------------ 16 Version 12.0 17 ------------ 18 19 * [libc++] [P0482] [C++20] Implement missing bits for codecvt and codecvt_byname. 20 21 This commit added new instantiations with char8_t for classes codecvt and 22 codecvt_byname in <locale> in the library. 23 24

<iostream> in 111 the library. This was done after noticing that many programs that used streams 112 ended up containing weak definitions of these classes, which has a negative 113 impact on both code size and load times. This change is not an ABI break, 114 since we are just adding additional symbols. 115 116 x86_64-apple-apple-darwin 117 ------------------------- 118 Symbol added:

was for ease of testing. Specifically, 577 I thought that if a debug violation aborted, we could only test one violation per file. This made 578 it impossible to test debug mode. Which throwing behavior we could test more! 579 580 However, the throwing approach didn't work either, since there are debug violations underneath noexcept 581 functions. This lead to the introduction of `_NOEXCEPT_DEBUG`, which was only noexcept when debug 582 mode was off. 583 584 Having thought more and having grown wiser, `_NOEXCEPT_DEBUG` was a horrible decision. It was 585 viral, it didn't cover all the cases it needed to, and it was observable to the user -- at worst 586 changing the behavior of their program. 587 588 This patch removes the throwing debug handler, and rewrites the debug tests using 'fork-ing' style 589 death tests. 590 591 All Platforms (ignoring versioning namespaces) 592 ---------------------------------------------- 593 Symbol added: _ZNKSt3__119__libcpp_debug_info4whatEv 594 Symbol removed: _ZNKSt3__124__libcpp_debug_exception4whatEv 595 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC1ERKNS_19__libcpp_debug_infoE 596 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC1ERKS0_ 597 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC1Ev 598 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC2ERKNS_19__libcpp_debug_infoE 599 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC2ERKS0_ 600 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionC2Ev 601 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionD0Ev 602 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionD1Ev 603 Symbol removed: _ZNSt3__124__libcpp_debug_exceptionD2Ev 604 Symbol removed: _ZNSt3__129__libcpp_throw_debug_functionERKNS_19__libcpp_debug_infoE 605 Symbol removed: _ZTINSt3__124__libcpp_debug_exceptionE 606 Symbol removed: _ZTSNSt3__124__libcpp_debug_exceptionE 607 Symbol removed: _ZTVNSt3__124__libcpp_debug_exceptionE 608 609 610 x86_64-apple-apple-darwin 611 ------------------------- 612 Symbol added: __ZNSt3__111__libcpp_db10__insert_cEPvPFPNS_8__c_nodeES1_S1_S3_E 613 Symbol removed: __ZNSt3__111__libcpp_db10__insert_cEPv 614 615 * r355367 - Fix -fsanitize=vptr badness in <__debug> 616 617 This patch fixes a lifetime bug when inserting a new container into the debug database.
