since the rule DCL21-CPP has been removed from the CERT guidelines.

- Fixed incorrect formatting in ``clang-apply-repalcements`` when no ``--format``

The push and pop pragmas will save and restore the full diagnostic state
of the compiler, regardless of how it was set. That means that it is
possible to use push and pop around GCC compatible diagnostics and Clang
will push and pop them appropriately, while GCC will ignore the pushes
and pops as unknown pragmas. It should be noted that while Clang

supports the GCC pragma, Clang and GCC do not support the exact same set
of warnings, so even when using GCC compatible #pragmas there is no
guarantee that they will have identical behaviour on both compilers.

Clang also doesn't yet support GCC behavior for ``#pragma diagnostic pop``
that doesn't have a corresponding ``#pragma diagnostic push``. In this case
GCC pretends that there is a ``#pragma diagnostic push`` at the very beginning
of the source file, so "unpaired" ``#pragma diagnostic pop`` matches that
implicit push. This makes a difference for ``#pragma GCC diagnostic ignored``
which are not guarded by push and pop. Refer to
`GCC documentation <https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Pragmas.html>`_
for details.

Like GCC, Clang accepts ``ignored``, ``warning``, ``error``, and ``fatal``
severity levels. They can be used to change severity of a particular diagnostic
for a region of source file. A notable difference from GCC is that diagnostic
not enabled via command line arguments can't be enabled this way yet.

In addition to controlling warnings and errors generated by the compiler, it is
possible to generate custom warning and error messages through the following

On X86-64 target, this attribute changes the calling convention of a function.
The ``preserve_none`` calling convention tries to preserve as few general

also uses more general registers to pass arguments. This attribute doesn't
impact floating-point registers (XMMs/YMMs). Floating-point registers still
follow the c calling convention.
