Hi,

	Anyone with an 030 or 020 willing to run the attached program (after
building it)? Build with 'gcc -onewcycle newcycle.s'. Run with 'newcycle
<clk in Hz>'.
On my Quadra700 I use 'newcycle 25000000'. Also please run
'sed s/trapf/nop/<newcycle.s>newercycle.s' to replace the 040 nop
(trapf) with an actual
nop. Results from my quadra 700:

[kevdig@Quadra700 kevdig]$ ./newcycle 24800000
Empty loop:
        259.886246u, 0.132883s
        8263167.751478 loops/sec
        3.001270 cycles/loop
Noop loop:
        346.558951u, 0.149497s
        6196589.759992 loops/sec
        4.002201 cycles/loop
DBxx loop:
        346.663262u, 0.282339s
        6194725.205695 loops/sec
        4.003406 cycles/loop

 (OK, I lied about what I use for the clock for my 700).
