Rule 3.4: All uses of the #pragma directive shall be...

Hi,
What exactly does this rule mean?
How do i document a #pragma?

thanks,

I always create a list with frequently used pragmas with the rationale for their use, and put a short reference in the C source.
For seldom used pragmas, I put an extensive (§+ line) comment in the source, with the rationale for this single use.
It has satisfied all auditors to date.

FWIW,

MISRA is not concerned about the format of the documentation, just that the use (and the justification for the use) of each #pragma directive is recorded.

The method of documentation should be specified in the Software Management Plan (MISRA-C:2004 Section 4.1) and Compliance Matrix (MISRA-C:2004 Section 4.3.1).
