   9  *   - hints, cf below.
  10  *
  11  * A "bad macro" is a macro using free variables or when expanded
  12  * that influence the control-flow of the code. In those cases it
  13  * is preferable to expand the macro so that the coccinelle engine
  14  * has a more accurate representation of what is going on.
  15  *
  16  *
  17  *
  18  *
  19  * old: this file was also containing what is below but now we
  20  * try to expand on demand the macro found in the c file, so those cases
  21  * are not needed any more:
  22  *   - macros found in .c; macros that cannot be parsed.
  23  *     In the future should be autodetected
  24  *     (not so easy to do same for macros in .h cos require to access .h file)
  25  *   - macros found in .c; macros correctly parsed
  26  *     but where we cant detect that it will be a "bad macro"
  27  *
  28  * Some of those macros could be deleted and the C code rewritten because
  29  * they are "bad" macros.
  30  *
  31  * todo? perhaps better if could enable/disable some of those expansions
  32  * as different software may use conflicting macros.
  33  *
  34  *
  35  * can maybe have a look in sparse/lib.c to see a list of default #define
  36  * handled builtin apparently by gcc.
