F28M35H52C: How to prevent C2000 compiler to optipizme a function from C code

Ril Dank

Part Number: F28M35H52C

Hi,

In my C28 application, I would like to disable optimization only for a specific function or code block. And I would like to specify that directly inside the C code.

With gcc, I can do that with :

__attribute__((optimize("O0")))

static void unoptimizedFunction()

{

...

}

Is is possible to do the same with C2000 compiler ?

Thanks a lot!

Ril,

There is a pragma that you can use for this.

The FUNCTION_OPTIONS pragma allows you to compile a specific function in a C or C++ file with additional command-line compiler options. The affected function will be compiled as if the specified list of options appeared on the command line after all other compiler options. In C, the pragma is applied to the function specified. In C+ +, the pragma is applied to the next function.

#pragma FUNCTION_OPTIONS ( func , " additional options " )

There is more information on it in the C28x Compiler users guide. In my version it is on page 122.
