Command line compiler options
This chapter explains how to set the compiler options from the command line,
and gives detailed reference information about each option.
Options summary
The following table summarizes the compiler command line options:
Command line option Description
--misrac |
Enables MISRA C-specific |
|
error messages |
--misrac_verbose |
Enables verbose logging of |
|
MISRA C checking |
|

Descriptions of options
The following section gives detailed reference information about each compiler option.
--misrac --misrac[={tag1,tag2-tag3,…|all|required}]
Use this option to enable the compiler to check for deviations from the rules described in the MISRA Guidelines for the Use of the C Language in Vehicle Based Software. By
using one or more arguments with the option, you can restrict the checking to a specific subset of the MISRA C rules. The possible arguments are described in this table:
Command line option |
Description |
--misrac |
Enables checking for all MISRA C rules |
--misrac=n |
Enables checking for the MISRA C rule with number n |
--misrac=m,n |
Enables checking for the MISRA C rules with numbers m |
|
and n |
--misrac=k-n |
Enables checking for all MISRA C rules with numbers from |
|
k to n |

Descriptions of options
Command line option |
Description |
|
|
--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 |
Table 3: Enabling MISRA C rules (--misrac) (Continued)
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.
Note: MISRA C is not supported by all IAR Systems products. If MISRA C checking is not supported by the compiler, using this option will generate an error.
To set the equivalent option in the 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 the IAR Embedded Workbench, select
Project>Options>General Options>MISRA C.
