Creates a new toctree "Support" under which we have distinct links to arch, platform, and compiler support. * Moved "Platform Support" from index landing page to new doc. * Created explicit "Architecture Support". Requested in https://github.com/llvm/llvm-project/issues/118964#issuecomment-2531503046. * Moved "Compiler Support" from Status toctree to new Support toctree. --------- Co-authored-by: Carlo Cabrera <github@carlo.cab>

The LLVM C Library
|
|
==================
|
|
|
|
.. warning::
|
|
LLVM-libc is not yet ABI stable; currently only static linking is supported.
|
|
LLVM-libc developers retain the right to modify the ABI of types used
|
|
throughout the library. Another libc should be preferred if ABI stability is
|
|
a requirement.
|
|
|
|
.. note::
|
|
LLVM-libc is not fully complete right now. Some programs may fail to build due
|
|
to missing functions. If you would like to help us finish LLVM-libc, check
|
|
out "`Contributing to the libc project <contributing.html>`__" in the sidebar
|
|
or ask on `discord <https://discord.com/channels/636084430946959380/636732994891284500>`__.

Introduction
|
|
============
|
|
|
|
LLVM-libc aspires to a unique place in the software ecosystem. The goals are:
|
|
|
|
- Fully compliant with current C23 and POSIX.1-2024 standards.
|
|
- Easily decomposed and embedded: Supplement or replace system C library
|
|
functionality easily. This is useful to get consistent math precision across
|
|
systems, or updated memory operations for newer microarchitectures. These
|
|
pieces will work on Linux, MacOS, Windows, and Fuchsia.
|
|
- The creation of fully static binaries without license implications.
|
|
- Increase whole program optimization opportunities for static binaries through
|
|
ability to inline math and memory operations.
|
|
- Reduce coding errors by coding in modern C++ through the use of lightweight
|
|
containers during coding that can be optimized away at runtime.
|
|
- Permit fuzzing and sanitizer instrumentation of user binaries including the
|
|
libc functions.
|
|
- A complete testsuite that tests both the public interface and internal
|
|
algorithms.
|
|
- `Fuzzing <https://github.com/llvm/llvm-project/tree/main/libc/fuzzing>`__
