--- Comment #9 from John David Anglin <danglin at gcc dot gnu.org> ---
Introduced in r202592:

    * tree-into-ssa.c (gate_into_ssa): New.
    (pass_data_build_ssa): Use it.
    * cgraph.h (expand_thunk): Update prototype.
    * cgraphunit.c (analyze_function): Expand thunks early.
    (expand_thunk): Fix DECL_CONTEXT of reust_decl;
    build proper cgraph; set in_ssa_p; clear bogus TREE_ASM_WRITTEN;
    set lowered flag; do not add new function.
    (assemble_thunks_and_aliases): Update.
    * tree-ssa.c (gate_init_datastructures): New gate.
    (pass_data_init_datastructures): Use it.

PA bug fix in r202594 needs to be backported to r202592 to see this.
