MSP430FR5994: Getting code composer to inline functions

Part Number: MSP430FR5994

I have tried everything I can think of to get code composer to inline functions. These efforts include:

Adding inline keyword to either declaration or definition of function
Adding #pragma FUNC_ALWAYS_INLINE to definition of function
Changing optimization level to both 3 (interprocedure) and 4 (whole program)
Varying opt-for-speed to 5
Changing language to C99 rather than C89

What other things should I try? What is the best way to verify it is inlining correctly?

Other notes:

Using compiler version TI 20.2.5.LTS
Have a simple example I am happy to share

The best/only way to check to see if a function has been inlined is to look at the result. Either telling the compiler to output assembly source or disassembling the final output.

I don't know about that compiler but GCC inlilnes even if you don't want it. (Can be disabled of course.) But put the function in a different file and it will never be inlined.

As David mentioned we support GCC in commend line mode you can try it. We provide the makefile that you can use.
