tree-ssa.c: Include tree-cfg.h and tree-dfa.h.
2016-08-17 Richard Biener <rguenther@suse.de>
* tree-ssa.c: Include tree-cfg.h and tree-dfa.h.
(verify_vssa): New function verifying virtual SSA form.
(verify_ssa): Call it.
* tree-ssa-loop-manip.c (slpeel_update_phi_nodes_for_guard2):
Do not apply loop-closed SSA handling to virtuals.
* ssa-iterators.h (op_iter_init): Handle GIMPLE_TRANSACTION.
* tree-into-ssa.c (prepare_use_sites_for): Skip virtual SSA names
when rewriting their symbol.
(prepare_def_site_for): Likewise.
* tree-chkp-opt.c (chkp_reduce_bounds_lifetime): Clear virtual
operands of moved stmts.
