unroll.i

source code for arithmatic coding

/*  unroll.i
  Used for loop unrolling, duplicates the given code fragment a specified
  number of times.
  ---------------------------------------------------------- 
  Precondition:
	#define UNROLL_NUM	Number of repetitions
	#define UNROLL_CODE	Code to repeat
  To use:
	#include "unroll.i"
  Result:
	The code UNROLL_CODE repeated UNROLL_NUM times.
  ---------------------------------------------------------- 

  For example:
        The program fragment:
		...
		i=0;
		#define UNROLL_NUM 3
		#define UNROLL_CODE  printf("%i",i++);
		#include "unroll.i"
		...

	is equivalent to:
		...
		i=0;
		printf("%i",i++);
		printf("%i",i++);
		printf("%i",i++);
		...
  ---------------------------------------------------------- 
  If the number of times the code fragment is to be repeated is greater
  than a certain number (here, 32), then a loop is added to repeat the code
  fragment as required.
