 Compiler Support
 ================
 
-As of now only ``Clang`` is fully supported.
+``LLVM libc`` compiles from both ``Clang`` and ``GCC`` but for maximum
+performance we recommand using ``Clang``.
 
-We are in the process of supporting ``GCC`` but some memory function implementations rely on `compiler intrinsics`__ that are not currently available in ``GCC``.
+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 version
 ===============
 
  - ``Clang 11``
+ - ``GCC 12.2```
