Okay, I think this patch was applied in the mean time.
Just some 20-30 temp files are left from a full run of the testsuite.
So I rewrote my patch, and found this time it looks
feasible to avoid all remaining temp files with unpredictable
random names, so that is an improvement over the state earlier
this year.
Attached is my new patch, to clean up the rest of the -save-temps
files. That consist just of a couple of @file parameters.
I added a few test cases, and the testsuite runs without any
temp files leaking.
Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?
Thanks
Bernd.

Subject: [PATCH] Fix -save-temp leaking lto files in /tmp
When linking with -flto and -save-temps, various
temporary files are created in /tmp.
The same happens when invoking the driver with @file
parameter, and using -L or -I options.
2020-12-12 Bernd Edlinger <bernd.edlin...@hotmail.de>
* collect-utils.c (collect_execute): Check dumppfx.
* collect2.c (maybe_run_lto_and_relink, do_link): Pass atsuffix
to collect_execute.
(do_link): Add new parameter atsuffix.
(main): Handle -dumpdir option. Skip one argument for
-o, -isystem and -B options.
* gcc.c (make_at_file): New helper function.
(close_at_file): Use it.
gcc/testsuite:
2020-12-12 Bernd Edlinger <bernd.edlin...@hotmail.de>
* gcc.misc-tests/outputs.exp: Adjust testcase.
