I believe LLVM toolchains also (by default) exclude debug information, which gc (go compiler) would need to be told to explicitly exclude.

You generally need to run the code through some rewriters that, as far as I recall, drop those symbols anyways -- these CPUs can't execute an elf binary directly from flash.

As a data point, TinyGo includes the debug info by default. There is a "-no-debug" option to turn off the inclusion though.
