Hi all,
This patch series contributes initial OpenMP and OpenACC support for AMD
GCN GPUs.
The test results are not yet perfect, but there are many more passes than
failures, so this is a good starting point. The rest of the issues can
be addressed as bugs during stage 3.
I have another, unfinished, patch to massage the testsuite itself. I'll
post this shortly, once I've finished checking the forward port is
appropriate.
This series implements only single-worker support for OpenACC. Julian
Brown may post the multiple-worker support soon, if it isn't too
difficult to forward-port. Otherwise that will have to wait for GCC 11.
