      The dwarf2out_cfi_label function is privatized, the

    • ia64: Use pc_rtx to save the return address. · 5f740973 
      When actually emitting dwarf2, this now produces proper results.
When emitting ia64 unwind info, this removes a hard-coded assumption.

        * config/ia64/ia64.c (ia64_expand_prologue): Use pc_rtx to
        indicate the return address save.

    • arm: Use REG_CFA_REGISTER instead of UNSPEC_STACK_ALIGN. · ddc6e7d6 
      This requires a bit of extra preparation in arm_unwind_emit, in
order to handle the change for ARM unwinding.

    • vax: Emit prologue as rtl. · a3515605 
      Not that there's much rtl to emit, since the CALL instruction
interpreting the procedure entry mask does almost all the work.
However, it means we're no longer emitting dwarf2 via the
text-based entry points.

        * config/vax/vax.md (define_c_enum unspecv): New.  Define the
        VUNSPEC_* constants here instead of via define_constants.
        (VUNSPEC_PEM): New constant.
        (procedure_entry_mask): New insn.
        (prologue): New expander.
        * config/vax/vax.c (vax_add_reg_cfa_offset): New.
        (vax_expand_prologue): Rename from vax_output_function_prologue;
        emit rtl instead of text.
        (TARGET_ASM_FUNCTION_PROLOGUE): Remove.
        (print_operand): Add 'x' prefix.
