(varpool_decide_const_value_known): Remove. * tree-ssa-ccp.c (get_base_constructor): Use it. * lto-cgraph.c (compute_ltrans_boundary): Likewise. * expr.c (string_constant): Likewise. * tree-ssa-loop-ivcanon.c (constant_after_peeling): Likewise. * ipa.c (ipa_discover_readonly_nonaddressable_var, function_and_variable_visibility): Likewise. * gimplify.c (gimplify_call_expr): Likewise. * gimple-fold.c (get_symbol_constant_value): Likewise. * varpool.c (varpool_decide_const_value_known): Replace by... (const_value_known_p): ... this one; handle other kinds of DECLs too and work for automatic vars. (varpool_finalize_decl): Use const_value_known_p. * lto.c (lto_promote_cross_file_statics): Use const_value_known_p. * g++.dg/tree-ssa/pr45605.C: New testcase.
