[PATCH 00/11] OpenMP: Deep struct dereferences

This is a series of patches to support deep struct dereferences for
OpenMP 5.0 (i.e. with multiple arrow operators,
"a->b[foo]->c[lo:hi]"). Apart from a couple of general bug fixes, the
main parts of this comprise:
1. Topological sorting of OMP clauses by base pointer dependencies.
2. Hoisting of struct sibling list handling out of
gimplify_scan_omp_clauses.
These patches replace and continue from the last part of the
previously-posted series:
https://gcc.gnu.org/pipermail/gcc-patches/2021-August/577219.html
and (still) depend on the parts of 1 through 7 of that series.
The patches have been bootstrapped & regression tested individually with
offloading to NVPTX (though some prior to the most recent rebase).
OK?
Thanks,
Julian

Remove base_ind/base_ref handling from extract_base_bit_offset
OpenMP 5.0: Clause ordering for OpenMP 5.0 (topological sorting by
base pointer)
Remove omp_target_reorder_clauses
OpenMP/OpenACC: Hoist struct sibling list handling in gimplification
OpenMP: Allow array ref components for C & C++
OpenMP: Fix non-zero attach/detach bias for struct dereferences
Not for committing: noisy topological sorting output
