tree-phinode.c (resize_phi_node): Abort when LEN is strictly greater than PHI_ARG_CAPACITY.
* tree-phinode.c (resize_phi_node): Abort when LEN is strictly
greater than PHI_ARG_CAPACITY.
(reserve_phi_args_for_new_edge): Initialize the new PHI
argument to NULL_TREE. Increment PHI_NUM_ARGS.
(add_phi_arg): Add a PHI argument to the slot given by
E->dest_idx.
(remove_phi_arg_num): Do not write to PHI_ARG_EDGE.
* tree-flow-inline (phi_arg_from_edge): Return E->dest_idx.
* tree-ssa.c (ssa_redirect_edge): Check for a missing PHI
argument by looking at PHI_ARG_DEF.
(verify_phi_args): Check for a missing PHI argument. Remove
the check for duplicate PHI arguments.
* tree.h (PHI_ARG_EDGE): Redefine in terms of EDGE_PRED.
(phi_arg_d): Remove e.
