Are you not aware of the gcc compiler option "-S"? Compile your
"Hello, world" C program with it and there you go. For the ABI,
please refer to the documentation, specifically the ABI
subsection in Chapter 6 (CRIS compiler specifics) at

Do you have a specific need for assembly programming?
FWIW, I see no practical need for application programming in
assembly (i.e. outside of *small* parts of the Linux kernel and
certain low-level library details). Most kernel drivers are
written in C. You can't beat the GCC compiler, can you? ;-)

Yes, or .s if you don't want it preprocessed with the C
preprocessor. Like with i386 and others instruction sets
supported by the GNU tool set.
