range_fits_type_p()

bool range_fits_type_p ( const irange * vr, unsigned dest_precision, signop dest_sgn )

extern

range_of_var_in_loop()

bool range_of_var_in_loop ( vrange & v, tree name, class loop * l, gimple * stmt, range_query * query )

extern

Set V to the range of NAME in STMT within LOOP.  Return TRUE if a
range was found.
