Hi, This patch series comprises an updated version of manual deep copy support for OpenACC 2.6. This was last posted upstream starting here:
https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00823.html The reference counting changes from the 3rd patch from that submission have been reposted a few days ago here: https://gcc.gnu.org/ml/gcc-patches/2019-10/msg00238.html Tested with offloading to nvptx (as a series, with the above refcounting patch). OK for trunk? (A couple of these patches were approved already; further commentary will be given on individual patches.) Thanks, Julian Julian Brown (4): Add function for pretty-printing OpenACC clause names Use gomp_map_val for OpenACC host-to-device address translation Factor out duplicate code in
