You can use the same code as in tree-vectorizer.h:

#ifdef USE_MAPPED_LOCATION
  typedef source_location LOC;
  #define UNKNOWN_LOC UNKNOWN_LOCATION
  #define EXPR_LOC(e) EXPR_LOCATION(e)
  #define LOC_FILE(l) LOCATION_FILE (l)
  #define LOC_LINE(l) LOCATION_LINE (l)
#else
  typedef source_locus LOC;
  #define UNKNOWN_LOC NULL
  #define EXPR_LOC(e) EXPR_LOCUS(e)
  #define LOC_FILE(l) (l)->file
  #define LOC_LINE(l) (l)->line
#endif
