This is with -save-temps, right?
Yes. Without, there are no files left under /tmp and only
nvptx-merged-loop.xnvptx-none.mkoffload.309r.mach
nvptx-merged-loop.exe
in the current directory.
(As in the testsuite, -foffload=-fdump-rtl-mach was used.)
Interesting, in my test run (native only) I didn't trigger that problem.

The 'set' above should be 'exists'.

Hence, it looks fine now – given:
/* { dg-do run { target openacc_nvidia_accel_selected } } */
/* { dg-options "-foffload=-fdump-rtl-mach" } */
/* { dg-skip-if "" { *-*-* } { "*" } { "-O2" } } */
Thanks a lot! The dump implementation looks much cleaner now :-)
Cheers,
Tobias
