Compiler Support
================
``LLVM libc`` compiles from both ``Clang`` and ``GCC`` but for maximum
performance we recommend using ``Clang``.
Indeed, some memory function implementations rely on `compiler intrinsics`__
that are not currently available in ``GCC``.
As such we cannot guarantee optimal performance for these functions.
.. __: https://clang.llvm.org/docs/LanguageExtensions.html#guaranteed-inlined-copy
For platforms where only ``GCC`` is natively available but maximum performance
is required it is possible to bootstrap ``Clang`` with ``GCC`` and then use
``Clang`` to build the '`libc``" project.
Minimum supported versions
==========================
- ``Clang 11``
- ``GCC 12.2``
