- Run
makefrom the Cygwin/MinGW/Linux command line:
$ make clean $ make
- Run a test for
fibo:
$ ./toyasm[.exe] fibo.asm > fibo.toy $ ./toy[.exe] fibo.toy
When prompted give a 16-bit hexadecimal constant (e.g. 0008) from stdin
(the toy simulator features an interactive console).
Then the simulator executes and prints 0015 (21 in decimal) as the
correct result for the 8-th element of Fibonacci's sequence.
Similarly, you can run a test for popcount by entering a hexadecimal number;
the TOY simulator console will then return the number of ones in that number.
- Standard UNIX-based tools:
make,gcc.
