I am not sure.  It might be that swi is another of those bizarre ARM
instructions accepting immediates encoded in a strange way, with some
constants that are representable and others taking the same number of
bits that are not.  Maybe I had originally chosen 256³ for that reason,
but it was long enough ago for me to forget.

I will study the ARM ISA more seriously when porting no-threading.

The current version using "swi 43" compiles in Thumb mode, but is not
usable with minimal-threading.  Non-Thumb ARM works correctly, as far as
I know.

Thanks,
