[libc++][format] define __cpp_lib_format. (#98275) In order to define the format __cpp_lib_format to its initial value (201907) these papers need to be completed: - P0645R10 Text Formatting - P1652R1 Printf corner cases in std::format - 1361R2 Integration of chrono with text formatting The first two have been implemented for a while the latter is almost done. The next value (202106) requires: - P2216R3 std::format improvements which has been implemented The next value (202110) requires: - P2418R2 Add support for std::generator-like types to std::format - P2372R3 Fixing locale handling in chrono formatters The first one has been implemented for a while the latter is almost done. The latter paper is a DR against 1361R2 and both are implemented at the same time. We've had user feedback that the missing of the __cpp_lib_format makes their lives harder (https://github.com/llvm/llvm-project/issues/77773). The missing papers 1361R2 and P2372R3 are very close to completion and might completed before LLVM-19, but it will be a close call. This has been discussed in the monthly libc++ meeting and we decided to set the __cpp_lib_format so it will be set in LLVM-19. Based on the discussion and the implementation status the __cpp_lib_format is set to 202110. Fixes #77773
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
