Here's the syntax - that's from gcc output, btw:

        lis     3,0x00dff180@h
        ori     3,3,0x00dff180@l

load immediate shifted (by 16 bit), @h is high part of the symbol.)
followed by or immediate symbol@l, that is lower 16 bit.

Works fine with symbols; the assembler and linker know how to handle 
and relocate them.

All RISCy CPUs have at least one instruction pair with this property...
