Descriptions of options

Reference Guide

If the compiler is unable to check for a rule, specifying the option for that rule has no 
effect. For instance, MISRA C rule 15 is a documentation issue, and the rule is not 
checked by the compiler. As a consequence, specifying 

--misrac=15

 has no effect.

To set the equivalent option in IAR Embedded Workbench, select 
Project>Options>General Options>MISRA C or Project>Options>C/C++ 
Compiler>MISRA C.

--misrac_verbose

--misrac_verbose

Use this option to generate a MISRA C log during compilation and linking. This is a list 
of the rules that are enabled—but not necessarily checked—and a list of rules that are 
actually checked.

If this option is enabled, the compiler displays a text at sign-on that shows both enabled 
and checked MISRA C rules.

To set the equivalent option in IAR Embedded Workbench, select 
Project>Options>General Options>MISRA C.

 --module_name

--module_name=name 

Normally, the internal name of the object module is the name of the source file, without 
a directory name or extension. Use this option to specify an object module name.

To set the object module name explicitly, use the option 

--module_name=name

, for 

example:

iccavr prog --module_name=main

This option is useful when several modules have the same filename, because the 
resulting duplicate module name would normally cause a linker error; for example, 
when the source file is a temporary file generated by a preprocessor. 

--misrac=k-n

Enables checking for all MISRA C rules with numbers from 

 to n

--misrac=k,m,r-t

Enables checking for MISRA C rules with numbers k, m, and 

from r to t

--misrac=all

Enables checking for all MISRA C rules

--misrac=required

Enables checking for all MISRA C rules categorized as 

required
