@code{jal (r1,r0)}
This .long directive, the address of _myfunc, shifted right by 1 at link time.
4 @code{loadd _data1@@GOT(r12), (r1,r0)}
This loads the address of _data1, into global offset table (ie GOT) and its offset value from GOT loads into register-pair r2-r1.

This loads the address of _myfun, shifted right by 1, into global offset table (ie GOT) and its offset value from GOT loads into register-pair r1-r0.
