            Bug ID: 65021
           Summary: nvptx mkoffload doesn't clean up its temporary files
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openacc, openmp
          Severity: major
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tschwinge at gcc dot gnu.org
                CC: bernds at gcc dot gnu.org

The nvptx mkoffload doesn't clean up its temporary files, so ${TMPDIR-/tmp}/
slowly fills up with cc* files, "until it explodes".

Related to that, do we generally need to add atexit as well as signal handlers?

[PR other/65021] mkoffloads -save-temps handling, and cleanup cleanup

        gcc/
        PR other/65021
        * config/i386/intelmic-mkoffload.c (mkoffload_atexit): Rename
        function to...
        (mkoffload_cleanup): ... this.  Adjust all users.
        (maybe_unlink): Look at save_temps and verbose flags instead of
        debug flag.
        (main): Parse "-save-temps" flag.
        (generate_target_descr_file, generate_target_offloadend_file)
        (generate_host_descr_file, prepare_target_image): Pass it on.
        * config/nvptx/mkoffload.c (tool_cleanup): Implement.
        (mkoffload_cleanup): New function.
        (maybe_unlink): Look at save_temps and verbose flags instead of
        debug flag.
        (main): Instead of calling utils_cleanup, register atexit handler
        for mkoffload_cleanup.
        (main): Parse "-save-temps" flag.
        (compile_native, main): Pass it on.
        * lto-wrapper.c (compile_offload_image): Likewise.
