368faaca - [libc++] Revert "Protect users from relying on detail headers" & related changes

Mon, 28 Feb 2022 21:37:25 +0000

[libc++] Revert "Protect users from relying on detail headers" & related changesThis commit reverts 5aaefa51 (and also partly 7f285f48e77 and b6d75682f9,which were related to the original commit). As landed, 5aaefa51 hadunintended consequences on some downstream bots and didn't have propercoverage upstream due to a few subtle things. Implementing this issomething we should do in libc++, however we'll first need to addressa few issues listed in https://reviews.llvm.org/D106124#3349710.Differential Revision: https://reviews.llvm.org/D120683 List of files: /llvm-project-15.0.7/libcxx/include/__std_stream

5aaefa51 - [libcxx][modules] protects users from relying on detail headers

Fri, 25 Feb 2022 18:59:32 +0000

[libcxx][modules] protects users from relying on detail headerslibc++ has started splicing standard library headers into much morefine-grained content for maintainability. It's very likely that outdatedand naive tooling (some of which is outside of LLVM's scope) willsuggest users include things such as <__ranges/access.h> instead of, and Hyrum's law suggests that users will eventually begin torely on this without the help of tooling. As such, this commitintends to protect users from themselves, by making it a hard error foranyone outside of the standard library to include libc++ detail headers.Differential Revision: https://reviews.llvm.org/D106124 List of files: /llvm-project-15.0.7/libcxx/include/__std_stream

57b08b09 - Update more file headers across all of the LLVM projects in the monorepo

Sat, 19 Jan 2019 10:56:40 +0000

Update more file headers across all of the LLVM projects in the monorepoto reflect the new license. These used slightly different spellings thatdefeated my regular expressions.We understand that people may be surprised that we're moving the headerentirely to discuss the new license. We checked this carefully with theFoundation's lawyer and we believe this is the correct approach.Essentially, all code in the project is now made available by the LLVMproject under our new license, so you will see that the license headersinclude that license only. Some of our contributors have contributedcode under our old license, and accordingly, we have retained a copy ofour old license notice in the top-level files in each project andrepository.llvm-svn: 351648 List of files: /llvm-project-15.0.7/libcxx/include/__std_stream

a016efb1 - [Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows

Wed, 31 May 2017 22:07:49 +0000

[Libc++] Use #pragma push_macro/pop_macro to better handle min/max on WindowsSummary:This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning.This patch changes libc++ to use `#pragma push_macro` to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.Reviewers: mclow.lists, bcraig, compnerd, EricWFReviewed By: EricWFSubscribers: cfe-commits, krytarowskiDifferential Revision: https://reviews.llvm.org/D33080llvm-svn: 304357 List of files: /llvm-project-15.0.7/libcxx/include/__std_stream

Enable and fix warnings during the build.Although CMake adds warning flags, they are ignored in the libc++ headersbecause the headers '#pragma system header' themselves.This patch disables the system header pragma when building libc++ and fixesthe warnings that arose.The warnings fixed were:1. - anonymous structs are a GNU extension2. - anonymous structs are a GNU extension.3. <__hash_table> - Embedded preprocessor directives have undefined behavior.4. - Definition is missing noexcept from declaration.5. <__std_stream> - Unused variable.llvm-svn: 242623 List of files: /llvm-project-15.0.7/libcxx/include/__std_stream

d7cda068 - Partial implementation of N3665. This paper was not voted into the C++1y draft. However I was looking at it and with some experimentation realized that I could partially implement it, and at the same time offer a performance optimization to cout. I simply added an xsputn override to the cout filebuf. The override does nothing special at all if there is a non-trivial codecvt installed. However if the codecvt returns true for always_noconv(), then this function can dump an entire string to fwrite, instead of doing it a character at a time under overflow(). This just makes sense. I stopped short of a full implementation of N3665 because in order to do so, xsputn would have to allocate a buffer when always_noconv() returned false, and I don't want to go to that expense.
