GCC-like attributes with TI v5.1.1

Tobias Matschke

I am having trouble with GCC-like attribute statements.

For example the declaration

void vIRQHandler(void) __attribute__((naked));

gives me a compiler warning #1173-D unknown attribute "naked" and does not do the trick.

Does somebody have a clue how to do this correctly with the TI compiler? I would really appreciate a link to some sort of expressions in GCC and their equivalents in the TI compiler. It seems there are many things that just don't work the same way.

Thanks a lot!

Please see this wiki article about GCC extensions. You'll discover, by its omission, that the attribute naked is not supported.

Thanks and regards,

OK, thanks.

Can you suggest a workaround?

You could implement it in hand-coded assembly. I agree that calling this a workaround isn't quite right.

Thanks and regards,

The thought occured to me aswell...

But I had another idea. You might have the background knowledge to tell if it is feasible or not:

How about building a library with gcc and using that library in my project with the TI compiler? Is the TI compiler binary compatible with gcc? I.e. using the same registers to pass parameters in function calls etc.?

Would this be a possibility?

Yes. I presume we are talking about the ARM compiler. You must use the same ABI (application binary interface) between the compilers. That is straightforward. The default ABI of the TI ARM compiler is --abi=eabi. This ABI is also the default of every ARM gcc compiler I know about.

Thanks and regards,
