**Diagnostic text:**

+----------------------------------------------------------------------------------------------------------------------------------------------------------------------+
|
|
|:warning:`warning:` |nbsp| :diagtext:`the number of preprocessor source tokens (`:placeholder:`A`:diagtext:`) exceeds this token limit (`:placeholder:`B`:diagtext:`)`|

|
|
+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
|
|
|
|
|
|
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.
