495 gimple_assign.
496 (rewrite_reductions_out_of_ssa): Strengthen "psi" to be a
497 gimple_phi_iterator, and "phi" to be a gimple_phi.
498 (phi_contains_arg): Require a gimple_phi.
499 (follow_ssa_with_commutative_ops): Strengthen return type from
500 gimple to gimple_phi, by converting a check for code GIMPLE_PHI to
501 a dyn_cast<gimple_phi>, and strengthening local "res" from gimple
502 to gimple_phi.
503 (detect_commutative_reduction_arg): Strengthen return type from
504 gimple to gimple_phi, and strengthen local "phi" to be a
505 gimple_phi.

511 a dyn_cast<gimple_phi>.
512 (detect_commutative_reduction): Strengthen return type and locals
513 "loop_phi", "phi", "close_phi" from gimple to gimple_phi,
514 introducing a checked cast of "stmt" in region guarded by

517 "loop_phi" to be a gimple_phi. Strengthen local "assign" from

519 (remove_phi): Require a gimple_phi.

521 (translate_scalar_reduction_to_array): We expect the first element
522 in each vector to be an arbitrary statement, but all of the
523 subsequent elements to be phi nodes. Hence the decls of gimple
524 locals "loop_phi" and "close_phi" are replaced with decls of gimple
525 "loop_stmt" and "close_stmt", with decls of the more-strongly typed
526 gimple_phi "loop_phi" and "close_phi" occurring lower down, within
527 the region where we're dealing with i > 0 and hence where we can
528 safely assign them using the checked cast as_a <gimple_phi>.
529 This allows many of the strengthenings from gimple to gimple_phi
530 above. We eliminate the local "stmt", since we can simply use
531 "loop_stmt".
532 (rewrite_commutative_reductions_out_of_ssa_close_phi): Strengthen
533 param "close_phi" from gimple to gimple_phi, and local "gsi" from

536 (scop_ivs_can_be_represented): Strengthen local "gsi" from
537 gimple_stmt_iterator to gimple_phi_iterator, and "phi" from gimple
538 to gimple_phi.
