Hi David!
Thanks for reporting.

I suppose what you're asking about is what appears in
<gcc-testresu...@gcc.gnu.org> reports as:
ERROR: c-c++-common/goacc/kernels-decompose-1.c: can't read "c_loop_i": no
such variable for " dg-line 24 l_loop_i[incr c_loop_i] "
UNRESOLVED: c-c++-common/goacc/kernels-decompose-1.c: can't read
"c_loop_i": no such variable for " dg-line 24 l_loop_i[incr c_loop_i] "
Etc.
However, per the reports posted there, these really only (!) appear to
fail for your "Native configuration is powerpc-ibm-aix7.2.3.0" testing,
strange. Which versions of DejaGnu and Tcl are used?
On <https://cfarm.tetaneutral.net/machines/list/> I see there are AIX
systems gcc111, gcc119 -- maybe I'll have luck reproducing the issue
there.
Admittedly, using Tcl code inside DejaGnu directives is not most common,
but it does make sense conceptually (at least to me), and reportedly does
work with a large number of DejaGnu/Tcl versions combinations.

That one's not actually related to the new OpenACC 'kernels' testcases:
it's just the testsuite harness checking whether GCN offloading is
configured. (See <https://gcc.gnu.org/PR88920> "GCC is not configured to
support amdgcn-unknown-amdhsa as offload target"; this should one appear
once per testsuite.)

It's not. At least not intentionally.

They are expected to work fine on all systems; they're not specific to
actual code offloading. So if something FAILs, we shall resolve it.
