Standard ARM, MIPS, PowerPC, x86, and Z80 Asm syntax all have the destination on the far left. 68k, Alpha, PDP-11, SPARC, and VAX have the destination on the far right. The order is probably as contentious as the great endianness debate, but I think one of the most awkward parts of having src, dst order is that subtraction looks backwards. I prefer dst, src because it corresponds closely with the direction of assignment in higher-level languages: op a, b, c ; a = b op c
op a, b ; a op= b
