[libc] Remove LIBC_ERRNO_MODE_SYSTEM mode. (#153077) Use LIBC_ERRNO_MODE_SYSTEM_INLINE instead as the default for the "public packaging" (i.e. release mode) of an overlay build. The Bazel build has already switched to use it by default in 5ccc734fa0355f971f8f515457a0bece33ab6642. This should be a safe change, as LIBC_ERRNO_MODE_SYSTEM_INLINE works a drop-in (but simpler) LIBC_ERRNO_MODE_SYSTEM replacement. Remove the associated code paths and config settings. Fixes issue #143454.
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.
