3f786833 - [libc++] Implements 128-bit support in to_chars.

Thu, 30 Jun 2022 15:25:28 +0000

[libc++] Implements 128-bit support in to_chars.This is required by the Standard and makes it possible to add full128-bit support to format.The patch also fixes 128-bit from_chars "support". One unit testrequired a too large value, this failed on 128-bit; the fix was to addmore characters to the input.Note only base 10 has been optimized. Other bases can be optimized.Note the 128-bit lookup table could be made smaller. This will be done later. Ireally want to get 128-bit working in to_chars and format in the upcommingLLVM 15 release, these optimizations aren't critical.Reviewed By: #libc, ldionneDifferential Revision: https://reviews.llvm.org/D128929 List of files: /llvm-project-15.0.7/libcxx/include/__bits

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/__bits

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/__bits

b973e2e2 - [libc++] Introduce __bits

[libc++] Introduce __bitsIt has the low-level bit fiddling operations from bit. It eliminates a cyclic dependency between __bit_reference, bits, and vector.
