Compiler Warnings with "-Wpedantic"

[Masmiseim]

Hello NXP team,

could you test the target code for Freemaster (the one running on the microcontroller) with higher warning levels and make it warning-free? May I recommend the following warning flags:

-Wall

-Wextra

-Wpedantic

The code raises several Compiler-Warnings with the warning-settings from above. The following three warnings, lead to linker errors when LTO is activated:

The following linker Errors with LTO active are created when the warnings are not solved:

Yes, at first glance these seem to have nothing to do with the warnings. It took me a while to understand the problem.

GCC13 was used on iMXRT1170.

Thanks and best regards

I agree

To add to this, I also suggest to remove warnings generated with -Wundef (which seems not to be included in -Wall?)as the Freemaster header files checks a lot of potentially undefined precompiler constants.
