Tool/software:
I have encountered an odd CCS behaviour. When the compiler command input passes over the ~8000 char threshold, CCS will put the args into a x_ccsCompiler.opt file to then pass to the compiler. However, this specifically fails when compiling the FreeRTOS kernel code. See the snippet below that shows the compilation of the queue.c file failing. Note that below I have replaced our project root directory with C:/root, so the command line looks considerably shorter.

One thing that I have observed, is that the RTOS files are compiled using the absolute path, where the other files (c2000, local project source) are compiled using the relative path. See below a working compilation call. From my CCS project, I cannot figure out why the file paths might be different for the FreeRTOS source files vs other source files.

I should note that in our project we are not using the C2000 SDK as a product installed, instead it is a git submodule within the project itself.
