static unsigned int check_data_deps ( )

static

   Check the correctness of the data dependence analyzers.

Referenced by gate_check_data_deps().

bool for_each_index	(	tree *	addr_p,
		bool()(tree, tree , void *)	cbck,
		void *	data
	)

   Calls CBCK for each index in memory reference ADDR_P.  There are two
   kinds situations handled; in each of these cases, the memory reference
   and DATA are passed to the callback:

   Access to an array: ARRAY_{RANGE_}REF (base, index).  In this case we also
   pass the pointer to the index to the callback.

   Pointer dereference: INDIRECT_REF (addr).  In this case we also pass the
   pointer to addr to the callback.

   If the callback returns false, the whole search stops and false is returned.
   Otherwise the function returns true after traversing through the whole
   reference *ADDR_P.

             If the component has varying offset, it behaves like index
             as well.

char* get_lsm_tmp_name ( )

   Determines name for temporary variable that replaces REF.
   The name is accumulated into the lsm_tmp_name variable.
   N is added to the name of the temporary.
