Sat, 21 Dec 2024 12:01:48 +0000

[libc++][C++03] Use `__cxx03/` headers in C++03 mode (#109002)This patch implements the forwarding to frozen C++03 headers asdiscussed inhttps://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc. In theRFC, we initially proposed selecting the right headers from the Clangdriver, however consensus seemed to steer towards handling this in thelibrary itself. This patch implements that direction.At a high level, the changes basically amount to making each publicheader look like this:```// inside #ifdef _LIBCPP_CXX03_LANG# include <__cxx03/vector>#else // normal content#endif```In most cases, public headers are simple umbrella headers so there isn'tmuch code in the #else branch. In other cases, the #else branch containsthe actual implementation of the header. List of files: /llvm-project/libcxx/include/system_error

37dca605c9bd41732da010ee97ed15ad9585a37d - [libc++] Clean up includes of <__assert> (#80091)

Thu, 29 Feb 2024 15:12:22 +0000

[libc++] Clean up includes of <__assert> (#80091)Originally, we used __libcpp_verbose_abort to handle assertion failures. That function was declared from all public headers. Since we don't use that mechanism anymore, we don't need to declare __libcpp_verbose_abort from all public headers, and we can clean up a lot of unnecessary includes. This patch also moves the definition of the various assertion categories to the <__assert> header, since we now rely on regular IWYU for these assertion macros. rdar://105510916 List of files: /llvm-project/libcxx/include/system_error

Fri, 30 Sep 2022 13:22:01 +0000

[libc++] Fix ADL for `make_error_{code,condition}`Implement LWG 3629, by making lookup for make_error_code andmake_error_condition only consider names found by ADL. This is achievedby adding a block scope using-declaration for a function that will befound by unqualified lookup, preventing unqualified lookup fromcontinuing to enclosing scopes (the class scope, then enclosingnamespaces). The function named by the using declaration is notviable, so overload resolution must select a candidate found by ADL.This fixes https://github.com/llvm/llvm-project/issues/57614Differential Revision: https://reviews.llvm.org/D134943 List of files: /llvm-project/libcxx/include/system_error

0cc34ca7ecfc9d0efee322f60ed6c3169f4f70ca - [libc++] Define legacy symbols for inline functions at a finer-grained level

Mon, 11 Apr 2022 16:32:40 +0000

[libc++] Define legacy symbols for inline functions at a finer-grained levelWhen we build the library with the stable ABI, we need to include somefunctions in the dylib that were made inline in later versions of thelibrary (to avoid breaking code that might be relying on those symbols).However, those methods were made non-inline whenever we'd be buildingthe library, which means that all translation units would end up usingthe old out-of-line definition of these methods, as opposed to the newinlined version. This patch makes it so that only the translation unitsthat actually define the out-of-line methods use the old definition,opening up potential optimization opportunities in other translationunits.This should solve some of the issues encountered in D65667.Differential Revision: https://reviews.llvm.org/D123519 List of files: /llvm-project/libcxx/include/system_error

[libc++] Ensure that all public C++ headers include <__assert>This patch changes the requirement for getting the declaration of theassertion handler from including <__assert> to including any publicC++ header of the library. Note that C compatibility headers areexcluded because we don't implement all the C headers ourselves --some of them are taken straight from the C library, like assert.h.It also adds a generated test to check it. Furthermore, this newgenerated test is designed in a way that will make it possible toreplace almost all the existing test-generation scripts with thissystem in upcoming patches.Differential Revision: https://reviews.llvm.org/D122506 List of files: /llvm-project/libcxx/include/system_error
