For ARM, according to "info gas". There's a description in "9.3.4 ARM
Machine Directives". (Is an "apt-get install binutils-doc" perhaps
required?)

For other architectures, I find that either:

; Register synonyms:
   Z      = 30             ; r31:r30 (e.g. For use with adiw)
   ZL     = 30             ; r30
   ZH     = 31             ; r31

and

   .equ r30, 30
   .equ r31, 31

work fine on those tried.
