Descriptions of options

Reference Guide

 --diagnostics_tables

--diagnostics_tables {filename|directory}

Use this option to list all possible diagnostic messages in a named file. This can be very 
convenient, for example, if you have used a pragma directive to suppress or change the 
severity level of any diagnostic messages, but forgot to document why.

This option cannot be given together with other options.

If a 

 is specified, the compiler stores the output in that file.

If a 

 is specified, the compiler stores the output in that directory, in a file with 

the name 

diagnostics_tables.txt

. To specify the working directory, replace 

 with a period (

.

).

To output a list of all possible diagnostic messages to the file 

diag.txt

, use:

--diagnostics_tables diag 

If you want to generate a table to a file 

diagnostics_tables.txt

 in the working 

directory, you could use:

--diagnostics_tables .

Both 

\

 and 

/

 can be used as directory delimiters.

--disable_direct_mode

--disable_direct_mode

This option prevents the compiler from generating the direct addressing mode 
instructions 

LDS

 and 

STS

.

Using this option may in some cases reduce the size of the object code.

  --dlib_config

--dlib_config filename

Each runtime library has a corresponding library configuration file. Use the 

--dlib_config

 option to specify the library configuration file for the compiler. Make 

sure that you specify a configuration file that corresponds to the library you are using.

All prebuilt runtime libraries are delivered with corresponding configuration files. You 
can find the library object files and the library configuration files in the directory 

avr\lib\dlib

. For examples and a list of prebuilt runtime libraries, see Using a
