Descriptions of options--diag_remarkSyntax--diag_remark=tag[,tag,...]ParameterstagThe number of a diagnostic message, for example the messagenumber Pe177DescriptionUse this option to reclassify certain diagnostic messages as remarks. A remark is theleast severe type of diagnostic message and indicates a source code construction thatmay cause strange behavior in the generated code. This option may be used more thanonce on the command line.Note: By default, remarks are not displayed; use the --remarks option to displaythem.Project>Options>C/C++ Compiler>Diagnostics>Treat these as remarks--diag_suppressSyntax--diag_suppress=tag[,tag,...]ParameterstagThe number of a diagnostic message, for example the messagenumber Pe117DescriptionUse this option to suppress certain diagnostic messages. These messages will not bedisplayed.

A warningindicates an error or omission that is of concern, but which will not cause the compiler148MSP430 IAR C/C++ CompilerReference Guide
Compiler optionsto stop before compilation is completed. This option may be used more than once on thecommand line.Project>Options>C/C++ Compiler>Diagnostics>Treat these as warnings--diagnostics_tablesSyntaxParametersDescription--diagnostics_tables {filename|directory}For information about specifying a filename or a directory, see Rules for specifying afilename or directory as parameters, page 140.Use this option to list all possible diagnostic messages in a named file. This can beconvenient, for example if you have used a pragma directive to suppress or change theseverity level of any diagnostic messages, but forgot to document why.This option cannot be given together with other options.This option is not available in the IAR Embedded Workbench IDE.--dlib_configSyntaxParametersDescription--dlib_config filenameFor information about specifying a filename, see Rules for specifying a filename ordirectory as parameters, page 140.Each runtime library has a corresponding library configuration file. Use this option tospecify the library configuration file for the compiler. Make sure that you specify aconfiguration file that corresponds to the library you are using.All prebuilt runtime libraries are delivered with corresponding configuration files. Youcan find the library object files and the library configuration files in the directory430\lib. For examples and a list of prebuilt runtime libraries, see Using a prebuiltlibrary, page 48.If you build your own customized runtime library, you should also create acorresponding customized library configuration file, which must be specified to thecompiler. For more information, see Building and using a customized library, page 55.Note: This option only applies to the IAR DLIB runtime environment.Part 2. Compiler reference149
