[Gomp-discuss] gfortran ... scanner

[Lars Segerlund]

 I had a small look at gfortran yesterday, and one of the nice things I found 
was this:

 gcc/gcc/fortran/scanner.c      line 301        :

/* Skip a comment.  When we come here the parse pointer is positioned
   immediately after the comment character.  If we ever implement
   compiler directives withing comments, here is where we parse the
   directive.  */

static void
skip_comment_line (void)
{
  char c;

  do
    {
      c = next_char ();
    }
  while (c != '\n');

  gfc_advance_line ();
}


 So perhaps this is a place to start ?

 I am currently looking at the omp spec to see it it's resonable to treat the 
openMP directives as function calls in the frontend and perhaps postpone 
processing until the middle end of gcc ( Gimplification and such ), and all 
processing until SSA is reached.
