        PR debug/43293
        * target.h (struct gcc_target): Add code_end hook.
        * target-def.h (TARGET_ASM_CODE_END): Define to hook_void_void
        if not yet defined.
        (TARGET_ASM_OUT): Add TARGET_ASM_CODE_END.
        * toplev.c (compile_file): Call targetm.asm_out.code_end
        hook before unwind info/debug info output.
        * config/i386/winnt.c (i386_pe_file_end): Don't call ix86_file_end.
        * config/i386/linux.h (NEED_INDICATE_EXEC_STACK): Don't define.
        (TARGET_ASM_FILE_END): Define to file_end_indicate_exec_stack.
        * config/i386/linux64.h (NEED_INDICATE_EXEC_STACK): Don't define.
        (TARGET_ASM_FILE_END): Define to file_end_indicate_exec_stack.
        * config/i386/i386.c (ix86_file_end): Renamed to...
        (ix86_code_end): ... this.  Make static.  Don't call
        file_end_indicate_exec_stack.  Emit unwind info using
        final_start_function/final_end_function.
        (darwin_x86_file_end): Remove.
        (TARGET_ASM_CODE_END): Define.
        * config/i386/i386.h (TARGET_ASM_FILE_END,
        NEED_INDICATE_EXEC_STACK): Don't define.
        * config/i386/darwin.h (darwin_x86_file_end): Remove prototype.
        (TARGET_ASM_FILE_END): Define to darwin_file_end.
        * config/i386/i386-protos.h (ix86_file_end): Remove prototype.
        * doc/tm.texi (TARGET_ASM_CODE_END): Document.
