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.

|
|
|
|
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``
