Constructor & Destructor Documentation

◆ vec_info()

vec_info::vec_info ( vec_info::vec_kind kind_in,

Initialize the vec_info with kind KIND_IN and target cost data
TARGET_COST_DATA_IN.

Member Function Documentation

◆ add_pattern_stmt()

stmt_vec_info vec_info::add_pattern_stmt ( gimple * stmt,
stmt_vec_info stmt_info )
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 new_stmt_vec_info(), set_vinfo_for_stmt(), and STMT_VINFO_RELATED_STMT.

◆ free_stmt_vec_info()

void vec_info::free_stmt_vec_info ( stmt_vec_info stmt_info)
private

◆ free_stmt_vec_infos()

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

References free_stmt_vec_info(), NULL, and stmt_vec_infos.

Referenced by ~vec_info().

◆ insert_on_entry()

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

References gsi_insert_before_without_update(), GSI_SAME_STMT, gsi_start(), 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 )
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.

◆ lookup_def()

◆ lookup_dr()

◆ lookup_single_use()

stmt_vec_info vec_info::lookup_single_use ( tree lhs)
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 lookup_stmt(), NULL, and single_imm_use().

◆ lookup_stmt()

stmt_vec_info vec_info::lookup_stmt ( gimple * stmt)
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.

stmt_vec_info old_stmt_info )

◆ new_stmt_vec_info()

◆ remove_stmt()

void vec_info::remove_stmt ( stmt_vec_info stmt_info)
Permanently remove the statement described by STMT_INFO from the
function.   

References free_stmt_vec_info(), gcc_assert, gsi_for_stmt(), gsi_remove(), NULL, release_defs(), set_vinfo_for_stmt(), si, and unlink_stmt_vdef().

Referenced by vect_remove_stores(), vect_schedule_slp(), vect_set_loop_condition(), and vect_transform_loop().

◆ replace_stmt()

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

References gcc_assert, gimple_set_uid(), gimple_uid(), gsi_replace(), and gsi_stmt().

Referenced by vect_remove_slp_scalar_calls(), vectorizable_call(), and vectorizable_simd_clone_call().

◆ resync_stmt_addr()

stmt_vec_info vec_info::resync_stmt_addr ( gimple * stmt)
If STMT was previously associated with a stmt_vec_info and STMT now resides
at a different address than before (e.g., because STMT is a phi node that has
been resized), update the stored address to match the new one.  It is not
possible to use lookup_stmt () to perform this task, because that function
returns NULL if the stored stmt pointer does not match the one being looked
up.
