ssa-iterators.h (ssa_vuse_operand): New inline.
2016-08-18 Richard Biener <rguenther@suse.de>
* ssa-iterators.h (ssa_vuse_operand): New inline.
* tree-if-conv.c (ifc_temp_var): Update virtual operand.
(predicate_all_scalar_phis): Use remove_phi_node to remove
phi nodes predicated. Delay removing virtual PHIs.
(predicate_mem_writes): Update virtual operands.
(combine_blocks): Likewise. Propagate out remaining virtual PHIs.
(tree_if_conversion): Do not rewrite virtual SSA form.
* tree-phinodes.c (release_phi_node): Make static.
* tree-phinodes.h (release_phi_node): Remove.
