! Prune a few: uninteresting:
! { 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_i 0 c_loop_j 0 c_loop_k 0] }
! { dg-message "dummy" "" { target iN-VAl-Id } l_dummy } to avoid
! "WARNING: dg-line var l_dummy defined, but not used".
