5 Controlling Code Generation

5-40

Including M-File Information in Compiler Output

The annotation options allow you to control the type of annotation in the

Compiler-generated C or C++ code. These options let you include the comments

and/or source code from the initial M-file(s) as well as

#line preprocessor

directives. You can also use an annotation option to generate source file and

line number information when you receive run-time error messages. To control

code annotation, use

-A <option>

You can combine annotation options, for example, selecting both comments and

#line directives. The remaining sections focus on the different choices you can

use.

Controlling Comments in Output Code

Use the annotation:type option to include your initial M-file comments and

code in your generated C or C++ output. The possible values for

type are

•

all

• comments

• none

Not specifying any annotation type uses the default of all, which includes the

complete source of the M-file (comments and code) interleaved with the

generated C/C++ source.

The following sections show segments of the generated code from this simple

Hello, World example:

function hello

% This is the hello, world function written in M code

fprintf(1,'Hello, World\n' );

Note To improve the readability of your generated code, turn off

optimizations with

-O none or -g. The examples in this section have

optimizations off.
