Revert 00bee6fcd77f, which partially reverted libc++ commit aa7f377c965cAfter base 966fb94cb357, this revert is no longer necessary: stdint.hwill unconditionally define macros such as `SIZE_MAX`, `UINT64_C`, andothers.Submitted by: Nikolas Klauser MFC after: 1 monthReviewed by: impDifferential Revision: https://reviews.freebsd.org/D56746 List of files: /freebsd/lib/libc++/Makefile

00bee6fcd77f7812e967f85d1cacbc349ff312b3 - Partially revert libc++ commit aa7f377c965c, restoring stdint.h

Tue, 30 Dec 2025 20:49:35 +0100

Partially revert libc++ commit aa7f377c965c, restoring stdint.hThis partially reverts upstream libc++ commit aa7f377c965c: [libc++] Remove libc++'s own stdint.h and locale.h (#107436) These headers are not doing anything beyond the system or compiler provided equivalent headers, so there's no real reason to keep them around. Reducing the number of C headers we provide in libc++ simplifies our header layering and reduces the potential for confusion when headers are layered incorrectly.The problem is that libc++'s own `stdint.h` _does_ do something: itdefines `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` beforeincluding the system `stdint.h`, causing the latter to expose macroslike `SIZE_MAX`, `UINT64_C`, and others.If the `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` macros are notexposed, C++ programs compiled for standards before C++11 can fail witherrors due to those macros not being available.PR: 292067MFC after: 1 month List of files: /freebsd/lib/libc++/Makefile

Fix buildworld with gcc 12 after llvm-19 importUnfortunately gcc 12's is not yet capable of compiling all of libc++19's C++23 code, which results in errors similar to: /usr/src/freebsd/src/contrib/llvm-project/libcxx/include/__algorithm/ranges_contains.h:41:3: error: 'static constexpr bool std::__1::ranges::__contains::__fn::operator()(_Iter, _Sent, const _Type&, _Proj)' must be a non-static member function 41 | operator()(_Iter __first, _Sent __last, const _Type& __value, _Proj __proj = {}) { | ^~~~~~~~ /usr/src/freebsd/src/contrib/llvm-project/libcxx/include/__algorithm/ranges_contains.h:48:3: error: 'static constexpr bool std::__1::ranges::__contains::__fn::operator()(_Range&&, const _Type&, _Proj)' must be a non-static member function 48 | operator()(_Range&& __range, const _Type& __value, _Proj __proj = {}) { | ^~~~~~~~Until we can get rid of gcc 12, work around this by making it compilelibc++ in C++20 mode instead.NOTE: The resulting libc++ library will not be C++23 compatible!
