One is open source,the other isn't.
As far as I understand, some consideration has been made to keep the syntax
for gputils the same or at least similar to mpasm. As a result the operation
of the application should be broadly the same, however gputils is not a
cloned implementation of mpasm (this assumes the logic used during
compilation doesn't change between revisions).
There is more than one way to get the approximately the same point. For
example, could you tell the difference between these two blocks of code once
compiled and running?:
1)
int main(){
char i = 0;
while(i<10){
print("%d",i);
i++;
}
return(0);
}
2)
int main(){
char i;
for(i=0,i<10,i++){
print("%d",i);
}
return(0);
}
