__FILE__, __LINE__, __FUNCTION__, and __func__

Can you elaborate on what you mean by not working.  I don't see any issue building code that uses these macros, but I haven't tried running resulting program.  Note that according to the Compiler User's Guide, only __FILE__ and __LINE__ are listed as predefined macros, so I am a little surprised that __FUNCTION__ and __func__ don't throw any errors.

I just tried building a simple example to run on a simulator under CCS. The following lines of code:

printf("FileName: %s\n",__FILE__);
printf("LineNumber: %d\n",__LINE__);
printf("FunctionName: %s\n",__FUNCTION__);
printf("FunctionName: %s\n",__func__);


 Produce the following output:


FileName: ../src/main.c
LineNumber: 204
FunctionName: main
FunctionName: main


The C6000 compiler used was v7.3.1. Based on the above, I would suppose that you should see similar results using the same compiler release.  I'll have to check with the compiler team about the undocumented __FUNCTION__ and __func__ support.

It turns out my test was built with the --gcc option, so that is why __func__ worked just fine for me.
