◆ adjust_before_returns_twice_call()
Helper function for gsi_safe_insert_before and gsi_safe_insert_seq_before. Replace SSA_NAME uses in G if they are PHI results of PHIs on E->dest bb with the corresponding PHI argument from E edge.

Helper function for gsi_safe_insert_before and gsi_safe_insert_seq_before. Find edge to insert statements before returns_twice call at the start of BB, if there isn't just one, split the bb and adjust PHIs to ensure that.

◆ gimple_find_edge_insert_loc()
|
static |
Insert the statement pointed-to by GSI into edge E. Every attempt is made to place the statement in an existing basic block, but sometimes that isn't possible. When it isn't possible, the edge is split and the statement is added to the new block. In all cases, the returned *GSI points to the correct location. The return value is true if insertion should be done after the location, or false if it should be done before the location. If a new basic block has to be created, it is stored in *NEW_BB.

Links sequence SEQ after the statement pointed-to by iterator I. MODE is as in gsi_insert_after. This function does not scan for new operands. It is provided for the use of the gimplifier, which manipulates statements for which def/use information has not yet been constructed. Most callers should use gsi_insert_seq_after.

Insert the sequence delimited by nodes FIRST and LAST after iterator I. M specifies how to update iterator I after insertion (see enum gsi_iterator_update). This routine assumes that there is a forward and backward path between FIRST and LAST (i.e., they are linked in a doubly-linked list). Additionally, if FIRST == LAST, this routine will properly insert a single node.

◆ gsi_remove()

Remove the current stmt from the sequence. The iterator is updated to point to the next statement. REMOVE_PERMANENTLY is true when the statement is going to be removed from the IL and not reinserted elsewhere. In that case we remove the statement pointed to by iterator I from the EH tables, and free its operand caches. Otherwise we do not modify this information. Returns true whether EH edge cleanup is required.
