/ synth_1to1_3dnow works the same way as the c version of

/ synth_1to1. this assembler code based 'decode-i586.s'

|
|
/ (by Stefan Bieschewski <stb@acm.org>), two types of changes

|
|
/ have been made:
|

|
|
/ - use {MMX,3DNow!} instruction for reduce cpu
|
||
|
|
/ - remove unused(?) local symbols
