Function Documentation

for_each_index()

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

extern

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.

get_lsm_tmp_name()

char * get_lsm_tmp_name ( tree ref, unsigned n, const char * suffix )

extern

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.

loop_containing_stmt()

class loop * loop_containing_stmt ( gimple * stmt )

inline

Returns the loop of the statement STMT.

tree_num_loop_insns()

unsigned tree_num_loop_insns ( class loop * loop, eni_weights * weights )

extern

Computes an estimated number of insns in LOOP, weighted by WEIGHTS.
