! Aside from restricting this testcase to non-nvptx offloading, and duplicating
! it with 'dg-do link' for nvptx offloading, there doesn't seem to be a way to
! XFAIL the "UNRESOLVED: [...] compilation failed to produce executable", or
! get rid of it, unfortunately.

! { dg-additional-options "-foffload=-fopt-info-note-omp" }
! { dg-additional-options "-foffload=--param=openacc-privatization=noisy" }
! for testing/documenting aspects of that functionality.
! Prune a few: uninteresting, and varying depending on GCC configuration (data types):
! { dg-prune-output {note: variable 'D\.[0-9]+' declared in block isn't candidate for adjusting OpenACC privatization level: not addressable} }

! It's only with Tcl 8.5 (released in 2007) that "the variable 'varName'
! passed to 'incr' may be unset, and in that case, it will be set to [...]",
! so to maintain compatibility with earlier Tcl releases, we manually
! initialize counter variables:
! { dg-line l_dummy[variable c_compute 0 c_loop 0] }
! { dg-message "dummy" "" { target iN-VAl-Id } l_dummy } to avoid
! "WARNING: dg-line var l_dummy defined, but not used".  */
