Best regards,
The variable block got disordered at some point.
Use the correct ordering.

For the test implementation of the SuperH architecture a second serial serial port needs to be used. Unfortunately the currently used 'stdio' driver does not support multiple serial ports at the same time.
Switch to the 'file' driver which does support multiple ports and is sufficient for the nolibc-test usecase.

MBR, Sergey
Add support for SuperH/"sh" to nolibc. Only sh4 is tested for now.
The startup code is special:
__nolibc_entrypoint_epilogue() calls __builtin_unreachable() which emits a call to abort(). To make this work a function prologue is generated to set up a GOT pointer which corrupts "sp". __builtin_unreachable() is necessary for __attribute__((noreturn)). Also depending on compiler flags (for example -fPIC) even more prologue is generated.
Work around this by defining a nested function in asm.

Apologies, I haven't been able to test this yet as my board currently doesn't want to boot kernels newer than v6.5.0 and I have not been able to bisect the problem yet.
Can I test this on v6.5.0 as well?

In theory it should be OK as we try to support oldest supported kernels.
