# cstore.12_30 = VDEF <cstore.12_43>
cstore.12_30 = COMPLEX_EXPR <CR.13_36, CI.14_39>;
That does not make sense either. How can there be a VDEF on a gimple register
variable?
This is caused by the cselim pass which was added by:
2007-09-10 Michael Matz <[EMAIL PROTECTED]>
* tree-pass.h (pass_cselim): Declare new pass.
* passes.c (init_optimization_passes): Link in pass_cselim.
* tree-ssa-phiopt.c (tree_ssa_phiopt_worker): Renamed from
tree_ssa_phiopt; add do_store_elim parameter, handle it by calling
cond_store_replacement.
(condstoretemp): New static variable.
(cond_store_replacement): New function.
(tree_ssa_phiopt, tree_ssa_cs_elim): New wrappers around
tree_ssa_phiopt_worker.
(struct name_to_bb): New.
(get_non_trapping, name_to_bb_hash, name_to_bb_eq, add_or_mark_expr,
nt_init_block, nt_fini_block): New static functions.
(seen_ssa_names, nontrap_set): New static variables.
(gate_cselim, pass_cselim): Define new pass.
* common.opt (ftree-cselim): New flag.
* toplev.c (process_options): Set flag_tree_cselim if required.
