One would expect it to be two mov.b instructions (the converse of the code in bar()). Something like this: return s.s; 0: 6a 08 00 00 6a 08 00 00 mov.b @0x0:16,r0l 4: 6a 0a 00 00 6a 0a 00 00 mov.b @0x0:16,r0h } 8: 54 70 54 70 rts > void bar(short v) > { > s.s = v; > e: 6a 80 00 00 6a 80 00 00 mov.b r0h,@0x0:16 > 12: 6a 88 00 00 6a 88 00 00 mov.b r0l,@0x0:16 > } > 16: 54 70 54 70 rts -- Grant Edwards grante@visi.com ------ Want more information?
