        * tree-complex.c (update_complex_assignment): We are always in SSA
form.
        (expand_complex_div_wide): Likewise.
        (expand_complex_operations_1): Likewise.
        (expand_complex_libcall): Preserve EH info of the original stmt.
        (tree_lower_complex): Handle removed blocks.
        * tree.c (build_common_builtin_nodes): Do not set ECF_NOTRHOW
        on complex multiplication and division libcall builtins.

        * g++.dg/torture/pr85627.C: New testcase.
