Hi Martin,

Thanks for help. I'm using cl6x from Texas Instruments, it's used for TI C6000 DSPs.

Best Regards,
Yang Zhou

If the command line arguments are different that's not surprising.

The parts that deal with compiler argument parsing.

Probably you will want to introduce an object layer that describes
different compilers, and an environment variable to switch between

What's the other compiler you are using?
