; Loads R8 from the address in R10.
; Loads (conditionally) R2 from a word
; 960 bytes above the address in R5, and
; increments R5 by 960.
; const-struc is an expression evaluating
; to a constant in the range 0-4095.
; Store R3 as halfword data into address in
; R4, then increment R4 by 4
; Load R8 from a word 32 bytes above the
; address in R3, and load R9 from a word 36
; bytes above the address in R3
; Store R0 to address in R8, and store R1 to
; a word 4 bytes above the address in R8,
; and then decrement R8 by 16.
