124 (phi_contains_arg): Require a gimple_phi.
125 (follow_ssa_with_commutative_ops): Strengthen return type from
126 gimple to gimple_phi, by converting a check for code GIMPLE_PHI to
127 a dyn_cast<gimple_phi>, and strengthening local "res" from gimple

129 (detect_commutative_reduction_arg): Strengthen return type from

139 "loop_phi", "phi", "close_phi" from gimple to gimple_phi,

147 (translate_scalar_reduction_to_array): We expect the first element
148 in each vector to be an arbitrary statement, but all of the
149 subsequent elements to be phi nodes. Hence the decls of gimple
150 locals "loop_phi" and "close_phi" are replaced with decls of gimple
151 "loop_stmt" and "close_stmt", with decls of the more-strongly typed
152 gimple_phi "loop_phi" and "close_phi" occurring lower down, within
153 the region where we're dealing with i > 0 and hence where we can
154 safely assign them using the checked cast as_a <gimple_phi>.
155 This allows many of the strengthenings from gimple to gimple_phi
156 above. We eliminate the local "stmt", since we can simply use
157 "loop_stmt".

199 "copy".
