I curious as to why the code generated for these two move.w commands is
completely different. In the first assembly I used two variables (one equal to 0
and the other equal to 8). I tried doing a move using the variables added
together as my offset to register A1 and managed to get 33B9 0000 0000 0170 0000
0008. When I simply put an 8 in instead of the variables, I got the correct
code. 3379 0000 0000 0008. Any ideas??????
I'm using gnu as on a pc-cygwin system with a m68k target.
