Constructor & Destructor Documentation

◆ _bb_vec_info()

_bb_vec_info::_bb_vec_info ( vec< basic_block > _bbs,
vec_info_shared * shared )
Initialize a bb_vec_info struct for the statements in BBS basic blocks.   

References vec_info::add_stmt(), vec_info::bbs, gimple_set_uid(), gsi_end_p(), gsi_next(), gsi_start_bb(), gsi_start_phis(), gsi_stmt(), i, is_gimple_debug(), vec_info::nbbs, and si.

◆ ~_bb_vec_info()

_bb_vec_info::~_bb_vec_info ( )
Free BB_VINFO struct, as well as all the stmt_vec_info structs of all the
stmts in the basic block.   

References vec_info::bbs, gimple_set_uid(), gsi_end_p(), gsi_next(), gsi_start_bb(), gsi_start_phis(), gsi_stmt(), i, vec_info::nbbs, roots, and si.

Member Function Documentation

◆ add_pattern_stmt()

stmt_vec_info vec_info::add_pattern_stmt ( gimple * stmt,
stmt_vec_info stmt_info )
inherited
Record that STMT belongs to the vectorizable region.  Create a new
stmt_vec_info and mark VECINFO as being related and return the new
stmt_vec_info.   

References vec_info::new_stmt_vec_info(), vec_info::set_vinfo_for_stmt(), and STMT_VINFO_RELATED_STMT.

void vec_info::free_stmt_vec_info ( stmt_vec_info stmt_info)
privateinherited

◆ free_stmt_vec_infos()

void vec_info::free_stmt_vec_infos ( void )
privateinherited
Free the contents of stmt_vec_infos.   

References vec_info::free_stmt_vec_info(), NULL, and vec_info::stmt_vec_infos.

Referenced by vec_info::~vec_info().

◆ insert_on_entry()

void vec_info::insert_on_entry ( stmt_vec_info context,
gimple * new_stmt )
inherited
Like insert_seq_on_entry but just inserts the single stmt NEW_STMT.   

References gsi_insert_before_without_update(), GSI_SAME_STMT, gsi_start(), vec_info::insert_seq_on_entry(), and NULL.

Referenced by vect_init_vector_1().

◆ insert_seq_on_entry()

void vec_info::insert_seq_on_entry ( stmt_vec_info context,
gimple_seq seq )
inherited
Insert stmts in SEQ on the VEC_INFO region entry.  If CONTEXT is
not NULL it specifies whether to use the sub-region entry
determined by it, currently used for loop vectorization to insert
on the inner loop entry vs. the outer loop entry.   

References vec_info::bbs, dyn_cast(), gcc_assert, gsi_after_labels(), gsi_insert_seq_before(), gsi_insert_seq_on_edge_immediate(), GSI_SAME_STMT, loop::inner, loop_preheader_edge(), LOOP_VINFO_LOOP, and nested_in_vect_loop_p().

◆ lookup_def()

◆ lookup_dr()

◆ lookup_single_use()

stmt_vec_info vec_info::lookup_single_use ( tree lhs)
inherited
See whether there is a single non-debug statement that uses LHS and
whether that statement has an associated stmt_vec_info.  Return the
stmt_vec_info if so, otherwise return null.   

References vec_info::lookup_stmt(), NULL, and single_imm_use().

◆ lookup_stmt()

stmt_vec_info vec_info::lookup_stmt ( gimple * stmt)
inherited
If STMT has an associated stmt_vec_info, return that vec_info, otherwise
return null.  It is safe to call this function on any statement, even if
it might not be part of the vectorizable region.

inherited

◆ replace_stmt()

void vec_info::replace_stmt ( gimple_stmt_iterator * gsi,
stmt_vec_info stmt_info,
gimple * new_stmt )
inherited
Replace the statement at GSI by NEW_STMT, both the vectorization
information and the function itself.  STMT_INFO describes the statement
at GSI.
