: Nobody likes unrolling 1000000 iterations ;-)
That's not what loop unrolling means.
It means that you take a divisor of the number of loops to perform and
"unroll" the body of the loop that many times and decrease the loop index by
that amount.
That is, if your loop is something like:
#declare Ind = 1000000;
#while(Ind)
do_something()
#declare Ind = Ind-1;
#end
you convert it to something like:
#declare Ind = 1000000;
#while(Ind)
do_something()
do_something()
do_something()
do_something()
do_something()
do_something()
do_something()
do_something()
do_something()
do_something()
#declare Ind = Ind-10;
#end
This should parse faster.
