Hi james. Your mission is now to determine whether a number is a prime number or not.
A prime number can only be divided by 1 & itself ; for example 0 is is NOT a
prime number (can u divide something by 0??), 1 is NOT(exception), 2 is, 3 is, 4 isn't (coz 4/2=2), etc..
Have a look at this site
Input is given in d0.l, it's an unsigned number
Result in d0.l : =1 if the input is prime number, 0 if not
The routine CAN crashes every register, except a7
The routine cannot use fpu, libraries, etc.., and shuld work on an 030
It can only use a 512 bytes code section (shuld be enough:)
It can also use bruteforce!!
Rts is not included in size
Download the small package
It can only use a 1024 bytes code section and a 1 mb bss section wich is cleared
before the first call
Rts is included in size
To get speed, two tests will be performed: the first one will call alot of times the
routine with random numbers, the second one will clear Bss between calls. We'll take the average
of the two tests

The deadline is Sun, February 18th
