Hi Gregor,

There was a problem with the register allocator that
caused this problem. Fixed now....

  Subject: [Sdcc-user] code problem


  Hi all!
  I have a problem with this code (simple ascii-string to int conversion):

  int String2Int(unsigned char *s)
  {
    int i=0;
    int j=0;
    int factor=1;

    while (!(s[i]==0)) i++;
    i--;
    while (i>=0)  // <----------------------------------- here´s the problem
!
      {
      j=j+(factor*((s[i])-0x30));
      factor*=10;
      i--; // <----------------------------------------------- i is
decreased here
      }
    return (j);
  }

  when i is 0, it will be decreased to 0xff, but the loop will not
terminate. It seems as if sdcc does not recognize the signed int, so 0xff is
larger than 0 and the loop goes on.

  Is this a "bug" of sdcc or am I doing something wrong???


  Many greetings from germany,

  Gregor
