f4c1258d - [libc++] Add an option to disable wide character support in libc++

Mon, 23 Aug 2021 19:32:36 +0000

[libc++] Add an option to disable wide character support in libc++Some embedded platforms do not wish to support the C library functionalityfor handling wchar_t because they have no use for it. It makes sense forlibc++ to work properly on those platforms, so this commit adds a carve-outof functionality for wchar_t.Unfortunately, unlike some other carve-outs (e.g. random device), thispatch touches several parts of the library. However, despite the wideimpact of this patch, I still think it is important to support thisconfiguration since it makes it much simpler to port libc++ to someembedded platforms.Differential Revision: https://reviews.llvm.org/D111265 List of files: /llvm-project-15.0.7/libcxx/test/std/input.output/iostream.format/output.streams/ostream.rvalue/rvalue.pass.cpp

[libc++] Re-apply fdc41e11f (LWG1203) without breaking the C++11 buildfdc41e11f was reverted in e46c1def5 because it broke the C++11 build.We shouldn't be using enable_if_t in C++11, instead we must useenable_if<...>::type.

fdc41e11 - [libc++] Implement LWG1203

Tue, 22 Sep 2020 19:46:37 +0000

[libc++] Implement LWG1203Libc++ had an issue where nonsensical code like decltype(std::stringstream{} << std::vector{});would compile, as long as you kept the expression inside decltype inan unevaluated operand. This turned out to be that we didn't implementLWG1203, which clarifies what we should do in that case.rdar://58769296 List of files: /llvm-project-15.0.7/libcxx/test/std/input.output/iostream.format/output.streams/ostream.rvalue/rvalue.pass.cpp
