This series contains a rebased/updated/bug-fixed version of the patch
to place gang-local variables in GPU shared memory, last posted here:

  https://gcc.gnu.org/pipermail/gcc-patches/2019-November/534551.html

Further commentary on individual patches. I am posting this for review
now, but I would not expect to commit it until stage 1.

Thanks,

Julian
