Actually it's not quite in place for v7 even. The gcc in v7 still
generates bad code on volatile bitfield accesses.
And v5 probably needs even more changes in that area if I understood
alignment requirements for v5 correctly.
See separate discussion on 9 Nov last week regardign GCC PR #50521.
It would be great if we could get help from some gcc developers in
analysing the needed changes. The suggested patch which seems to fix
known code generation is not yet in gcc trunk and is why we have not
included it in the armv7hl gcc package even if it's been discussed a
number of times.
Let me know if Linaro can help. I see that Joey Ye from ARM is
working in this area as well.
