unroll.i：Code Content
  1. /*  unroll.i
  2.   Used for loop unrolling, duplicates the given code fragment a specified
  3.   number of times.
  4.   ---------------------------------------------------------- 
  5.   Precondition:
  6. #define UNROLL_NUM Number of repetitions
  7. #define UNROLL_CODE Code to repeat
  8.   To use:
  9. #include "unroll.i"
  10.   Result:
  11. The code UNROLL_CODE repeated UNROLL_NUM times.
  12.   ---------------------------------------------------------- 
  14.   For example:
  15.         The program fragment:
  16. ...
  17. i=0;
  18. #define UNROLL_NUM 3
  19. #define UNROLL_CODE  printf("%i",i++);
  20. #include "unroll.i"
  21. ...
  23. is equivalent to:
  24. ...
  25. i=0;
  26. printf("%i",i++);
  27. printf("%i",i++);
  28. printf("%i",i++);
  29. ...
  30.   ---------------------------------------------------------- 
  31.   If the number of times the code fragment is to be repeated is greater
  32.   than a certain number (here, 32), then a loop is added to repeat the code
  33.   fragment as required.
