23.4 Adding the Results of Compiler Checks to gnatcheck Output

The gnatcheck tool can include in the generated diagnostic messages and in the report file the results of the checks performed by the compiler. Though disabled by default, this effect may be obtained by using +R with the following rule identifiers and parameters:

To record restrictions violations (that are performed by the compiler if the pragma Restrictions or Restriction_Warnings are given), use the rule named Restrictions with the same parameters as pragma Restrictions or Restriction_Warnings.
To record compiler style checks(see Style Checking), use the rule named Style_Checks. A parameter of this rule can be either All_Checks, which enables all the standard style checks that corresponds to -gnatyy GNAT style check option, or a string that has exactly the same structure and semantics as the string_LITERAL parameter of GNAT pragma Style_Checks (for further information about this pragma, see Pragma Style_Checks).
To record compiler warnings (see Warning Message Control), use the rule named Warnings with a parameter that is a valid static_string_expression argument of GNAT pragma Warnings (for further information about this pragma, see Pragma Warnings). Note, that in case of gnatcheck 's' parameter, that corresponds to the GNAT -gnatws option, disables all the specific warnings, but not suppresses the warning mode, and 'e' parameter, corresponding to -gnatwe that means "treat warnings as errors", does not have any effect.

To disable a specific restriction check, use -RStyle_Checks gnatcheck option with the corresponding restriction name as a parameter. -R is not available for Style_Checks and Warnings options, to disable warnings and style checks, use the corresponding warning and style options.
