According to <gcc-testresu...@gcc.gnu.org> posts, this has been FAILing forever
for powerpc-ibm-aix7.2.0.0 (so, not a "new failure" as far as I can tell?),
ever since my 2019-06-19 r272452 '[PR90859] Document status quo for "[OMP]
Mappings for VLA different depending on 'target { c && { ! lp64 } }'"'. The
problem here relates to front end 'sizetype' internals, for which 'c && { !
lp64 }' doesn't seem to be quite the right conditional.
In PR95002, there is discussion about the actual C/C++ front end and/or
gimplifier changes assumed to be necessary to fix this for good. Spending time
on that would be more useful than figuring out the right testsuite-level
conditional -- but I don't have a good understanding of the relevant C/C++
language-level requirements, and the relevant front end vs. gimple-level
folding.
