More fine grained information about the stack layout is available by adding the

invocation.
The diagnostic information can be saved to a file in a machine readable format,
like YAML by adding the `-foptimization-record-file=<file>` command-line flag.
Results can be filtered by function name by passing
`-mllvm -filter-print-funcs=foo`, where `foo` is the target function's name.

The warning is issued if the number of pre-processor tokens exceeds
the token limit, which can be set in three ways:
1. As a limit at a specific point in a file, using the ``clang max_tokens_here``
pragma:
.. code-block:: c++
#pragma clang max_tokens_here 1234
2. As a per-translation unit limit, using the ``-fmax-tokens=`` command-line
flag:
.. code-block:: console
clang -c a.cpp -fmax-tokens=1234
3. As a per-translation unit limit using the ``clang max_tokens_total`` pragma,
which works like and overrides the ``-fmax-tokens=`` flag:
.. code-block:: c++
#pragma clang max_tokens_total 1234
These limits can be helpful in limiting code growth through included files.
Setting a token limit of zero means no limit.
Note that the warning is disabled by default, so -Wmax-tokens must be used
in addition with the pragmas or -fmax-tokens flag to get any warnings.
